First embodiment

First, please refer to FIG. 1 and FIG. 2. FIG. 1 and FIG. 2 are a top schematic perspective view and a bottom perspective schematic view of the antenna structure of the first embodiment, respectively. The first embodiment of the present invention provides an antenna structure Q1, which includes a substrate 1, a radiating element 2, a coupling element 3, a grounding element 4, a conductive element 5, and a feeding element 6. The radiating element 2 and the coupling element 3 can be disposed on the substrate 1, the feeding element 6 can be electrically connected (coupled) to the coupling element 3 and the grounding element 4 for feeding a signal, and the feeding element 6 can be A coaxial cable has a feeding end 61 and a grounding end 62. The feeding end 61 can be electrically connected to the coupling member 3, and the grounding end 62 can be electrically connected to the grounding member 4. In this way, the feeding member 6 can be used to feed a signal, and the conductive member 5 can be used to conduct the signal fed by the feeding member 6 to the grounding member 4.

In view of the above, please refer to FIG. 1 and FIG. 2 again. In terms of the first embodiment, the substrate 1 may include a first surface 11 (upper surface) and a second surface 12 (lower) relative to the first surface 11 Surface), the coupling member 3 may be disposed on the first surface 11 of the substrate 1, the radiating member 2 may be disposed on the second surface 12 of the substrate 1, whereby the coupling member 3 may be coupled to a coupling portion 23 of the radiating member 2 Separated and coupled with each other. However, in other embodiments (please refer to the sixth embodiment), the radiating element 2 and the coupling element 3 may be disposed on the same surface. It should be noted that, in terms of the embodiment of the present invention, the coupling member 3 and the spoke A coupling portion 23 of the radiation member 2 is coupled to each other, and the feeding member 6 and the radiation member 2 are separated from each other. In addition, the materials of the substrate 1, the radiating element 2, the coupling element 3, the grounding element 4, the conductive element 5, and the feeding element 6 are conventional technologies that are easily understood by those skilled in the art and will not be repeated here. For example, the radiating element 2, the coupling element 3, the grounding element 4, and the conductive element 5 may be a metal sheet, a metal wire, or other conductive bodies with conductive effects. It should be noted that the coupling part 23 of the coupling member 3 and the radiating member 2 is coupled to each other, which means that the coupling member 3 and the coupling part 23 are separated from each other, and the coupling method is not the same.

Next, please refer back to FIG. 1, the conductive member 5 can be disposed on the first surface 11, and the conductive member 5 can be connected (coupled) between the coupling member 3 and the grounding member 4, and the conductive member 5 can be coupled with The piece 3 is integrally formed so that the conductive piece 5 extends from the coupling piece 3 to the grounding piece 4. The grounding member 4 is electrically connected to a metal conductor E, and the metal conductor E and the substrate 1 can be separated from each other, and the coupling part 23 of the grounding member 4 and the radiating member 2 is separated from each other. In addition, the conductive member 5 may have a first end 51 connected to the coupling member 3 and a second end 52 connected to the grounding member 4. In the first embodiment, the conductive member 5 may have an extension portion 53 extending away from the coupling member 3 and a bent portion 54 bent from the extension portion 53 and extending to the grounding member 4. In addition, the first end 51 may be located on the extension 53 and the second end 52 may be located on the bent portion 54. Thereby, the conductive member 5 can be connected to the coupling member 3 through the extending portion 53 (first end portion 51), and electrically connected to the grounding member 4 through the bent portion 54 (second end portion 52). In other words, as can be seen from FIG. 1, when the antenna structure Q1 is on the XY plane, the extending portion 53 can extend toward a first direction (negative X direction), and the bending portion 54 can toward a third direction (negative Y) Direction), and the extending portion 53 and the bending portion 54 are substantially perpendicular to each other.

Next, please refer back to FIG. 2, the radiating element 2 can be disposed on the substrate 1, the radiating element 2 can include a first radiating portion 21 for providing a first operating frequency band, and a second operating frequency band for providing a second operating frequency band The second radiating portion 22 and a coupling portion 23 connected between the first radiating portion 21 and the second radiating portion 22. Further, the first radiating portion 21 can be directed toward a first by the coupling portion 23 where the first radiating portion 21 and the second radiating portion 22 are connected One direction (negative X direction) extends, and the second radiating portion 22 can extend from the coupling portion 23 toward a second direction (positive X direction), where the first direction is different from the second direction. In other words, the first radiating portion 21 and the second radiating portion 22 respectively extend outward from the two opposite side ends of the coupling portion 23. Thereby, the extending direction of the coupling portion and the extending direction of the first radiating portion 21 and the second radiating portion 22 are substantially perpendicular to each other.

In light of the above, it is worth noting that, in the embodiment of the present invention, the length of the first radiating portion 21 is greater than the length of the second radiating portion 22, and the frequency range (bandwidth) of the first operating frequency band provided by the first radiating portion 21 , Bandwidth) is between 698MHz and 960MHz, and the frequency range of the second operating frequency band provided by the second radiating section 22 is between 1425MHz and 2690MHz, suitable for different LTE (Long Term Evolution) bands (Band) However, the present invention is not limited to this. Incidentally, for ease of description, the following embodiment will be described using an example in which the frequency range of the first operating band is between 698MHz and 960MHz, and the frequency range of the second operating band is between 1425MHz and 2690MHz.

Next, please refer to FIGS. 1 and 2 again. The area where the coupling element 3 and the coupling portion 23 overlap each other can be defined as a first coupling area Z1 (orthographic projection of the coupling element 3 on the XY plane and the coupling portion 23 the area where the orthographic projection on the XY plane overlaps each other), and the area of the first coupling zone Z1 (the degree of coupling between the coupling member 3 and the coupling part 23) and the frequency of the operating band generated by the antenna structure Q1 The size of the range (bandwidth) is proportional to the relationship. Furthermore, the area of the first coupling zone Z1 is inversely proportional to the center frequency of the operating band generated by the antenna structure Q1. In other words, when the first coupling zone Z1 is smaller, the frequency range of the operating band generated by the antenna structure Q1 will decrease, and the center frequency of the operating band generated by the antenna structure Q1 will increase. In addition, the area of the first coupling zone Z1 is proportional to the degree to which the impedance value corresponding to the center frequency of the antenna structure Q1 is close to a predetermined impedance value, that is, the larger the area of the first coupling zone Z1 (coupling member 3 The greater the degree of coupling between the coupling portion 23 and the coupling amount between the coupling element 3 and the coupling portion 23, the greater the impedance value corresponding to the center frequency of the antenna structure Q1 Close to the preset impedance value. Conversely, the smaller the area of the first coupling zone Z1 (the smaller the degree of coupling between the coupling member 3 and the coupling section 23, or the smaller the amount of coupling between the coupling member 3 and the coupling section 23), the center of the antenna structure Q1 The impedance value corresponding to the frequency will be further away from the preset impedance value.

It is worth noting that when the first coupling zone Z1 changes, the frequency range of the first operating band and the center frequency of the operating band will change more than the frequency range of the second operating band and the center frequency of the operating band, The second operating frequency band is higher than the first operating frequency band. In addition, it should be noted that, in order to facilitate understanding of the contents of the drawings, the area of the coupling portion 23 is smaller than the area of the coupling member 3 in the drawings, however, in other embodiments, the area of the coupling portion 23 may be larger than Or an area equal to the coupling 3. Furthermore, the area of the first coupling zone Z1 may be adjusted by adjusting the relative position between the coupling part 23 and the coupling 3 or adjusting the size of the coupling part 23 and the coupling 3.

According to the above, the distance that the conductive member 5 extends from the coupling member 3 to the grounding member 4 is defined as an extension length (the sum of the first length L1 and the second length L2), and the extension length of the conductive member 5 can be the same as that generated by the antenna structure Q1 The size of the frequency range of the operating band is in a proportional relationship, and the extension length of the conductive member 5 is inversely proportional to the magnitude of the impedance value corresponding to the center frequency of the operating band generated by the antenna structure Q1. That is, the smaller the extension length of the conductive member 5 is, the smaller the frequency range of the operating frequency band generated by the antenna structure Q1 is, and the greater the impedance value corresponding to the center frequency of the operating frequency band generated by the antenna structure Q1. Conversely, the greater the extension length of the conductive member 5, the smaller the impedance value corresponding to the center frequency of the operating band generated by the antenna structure Q1. It is worth noting that when the impedance value is closer to the preset impedance value, the value of the voltage standing wave ratio (VSWR) corresponding to the center frequency of the operating band is closer to 1. For example, when the impedance value is closer to the preset impedance value of 50 ohms, that is, the value of the voltage standing wave ratio corresponding to the center frequency of the operating frequency band is closer to 1. In other words, the extension length of the conductive member 5 can be adjusted according to requirements to adjust to the frequency range and voltage standing wave ratio of the desired operating band.

In addition, in the first embodiment, the conductive member 5 has an extended portion 53 and a bent portion 54 connected to the extended portion 53. Therefore, the extended length of the conductive member 5 can be a first length L1 of the extended portion 53 The total length of both of a second length L2 of the bent portion 54. The first length L1 may be calculated from the edge of the first coupling zone Z1 formed by the coupling member 3 and the coupling portion 23 to the edge of the bent portion 54, and the second length L2 may be calculated from the edge of the extended portion 53 to The junction between the bent portion 54 and the grounding member 4.

Next, please refer to FIG. 3 and Table 1 below. FIG. 3 is a schematic diagram of Voltage Standing Wave Ratio (VSWR).

Second embodiment

Please refer to FIG. 4, which is a schematic perspective top view of the antenna structure of the second embodiment. It can be understood from the comparison between FIG. 4 and FIG. 1 that the biggest difference between the second embodiment and the first embodiment is that the antenna structure Q2 provided in the second embodiment further includes One bridge part 7. In detail, the bridge member 7 can be disposed on the first surface 11 of the substrate 1 and connected (coupled) between the conductive member 5 and the ground member 4. The bridge 7 has a first side end 71, a second side end 72 opposite to the first side end 71, and a body 73 connected between the first side end 71 and the second side end 72. In the second embodiment, the first side end 71 can be connected to the bending portion 54, the body 73 can be electrically connected to the grounding member 4, in other words, the first side end 71 of the bridge member 7 can be connected to the second端部52。 The end 52.

Based on the above, it is worth noting that, in the second embodiment, the coupling member 3, the conductive member 5, and the bridge member 7 can be integrally formed. In addition, the structural characteristics of the substrate 1, the radiating element 2, the coupling element 3, the grounding element 4, the conductive element 5 and the feeding element 6 are similar to the foregoing embodiments, and will not be repeated here. It should be noted that the purpose of providing the bridge member 7 is to make the grounding member 4 easily attached to the substrate 1. Although the second embodiment describes that the bridge member 7 can be further provided, however, in other embodiments, There is no need to set the bridge 7. In other words, in the antenna structure Q2 provided with the bridge member 7, the ground terminal 62 of the feeding member 6 can also be electrically connected to the bridge member 7 or the ground member 4, so that the ground terminal 62 is indirectly connected to the ground member 4, however The invention is not limited to this. In addition, it is worth mentioning that, for example, the material of the bridge member 7 may be tin, and the material of the ground member 4 may be copper, but the invention is not limited thereto.

Third embodiment

Please refer to FIG. 5, which is a schematic perspective top view of the antenna structure of the third embodiment. It can be understood from the comparison between FIG. 5 and FIG. 1 that the biggest difference between the third embodiment and the first embodiment is that the conductive member 5'of the antenna structure Q3 in the third embodiment is different from the conductivity provided by the first embodiment Piece 5. For example, the conductive element 5'may be an inductive element disposed (crossed) between the coupling element 3 and the ground element 4. The inductive element may have a first end 51' and a corresponding end 51' second end 52'. The inductance element may be electrically connected to the coupling member 3 through the first end 51' and electrically connected to the grounding member 4 through the second end 52'.

In addition, the frequency range and frequency band of the operating band of the antenna structure Q3 can be indirectly changed by changing different inductance elements (conductive members 5') to adjust the inductance value The center frequency. In the third embodiment, the inductance value provided by the inductance element is proportional to the size of the frequency range of the operating band generated by the antenna structure Q3, and the degree of decrease (decrease) of the inductance value provided by the inductance element is The impedance value corresponding to the center frequency of the operating frequency band generated by the antenna structure Q3 is inversely proportional. In other words, the smaller the inductance value provided by the inductive element, the smaller the frequency range of the operating band generated by the antenna structure Q3, and the greater the impedance value corresponding to the center frequency of the operating band generated by the antenna structure Q3. Conversely, the larger the inductance value provided by the inductive element, the larger the frequency range of the operating frequency band generated by the antenna structure Q3, and the smaller the impedance value corresponding to the center frequency of the operating frequency band generated by the antenna structure Q3. For example, assuming that the inductance value of the inductance element is 6.8nH as a reference value, when the inductance value is larger, the frequency range of the operating band generated by the antenna structure Q3 will also increase, otherwise the frequency range of the operating band will increase Of reduction. In other words, when the inductance value is smaller, the impedance value of the center frequency is larger, and the low-frequency bandwidth is narrowed. Conversely, when the inductance value is larger, the impedance value of the center frequency is smaller, and the low-frequency bandwidth is widened.

It is worth mentioning that, compared with the antenna structure Q1 having the extending portion 53 and the bending portion 54 as the conductive member 5 in the first embodiment, when the inductive element is used as the conductive member 5'in the third embodiment, it can be substantially Reduce the volume of the antenna structure Q3. In addition, it should be noted that the structural features of the substrate 1, the radiating element 2, the coupling element 3, the grounding element 4, and the feeding element 6 in the third embodiment are similar to the foregoing embodiments, and are not repeated here. In addition, when the inductance element is used as the conductive member 5', it can be used not only to adjust the impedance matching between the low frequency and the high frequency, but preferably, the effect of adjusting the low frequency range (bandwidth) can also be achieved.

Fourth embodiment

Please refer to FIG. 6. FIG. 6 is a top schematic perspective view of the antenna structure of the fourth embodiment. It can be seen from the comparison between FIG. 6 and FIG. 5 that the biggest difference between the fourth embodiment and the third embodiment is that the antenna structure Q4 in the fourth embodiment further includes a bridge 7′, and the bridge 7′ may have the first The side end 71', the second side end 72' and the body 73'. bridging The element 7'may be provided between the inductive element 5'and the grounding element 4. Thereby, the first side end 71' of the bridge 7'can be electrically connected to the second end 52' of the inductance element 5', and the body 73' can be electrically connected to the grounding member 4. It should be noted that the structural features of the other elements in the fourth embodiment are similar to those in the foregoing embodiments, and will not be repeated here.

Fifth embodiment

First, please refer to FIG. 7, which is a schematic perspective top view of the antenna structure of the fifth embodiment. It can be understood from the comparison between FIG. 7 and FIG. 4 that the biggest difference between the fifth embodiment and the second embodiment is that the antenna structure Q5 in the fifth embodiment further includes an antenna disposed adjacent to the second radiating portion 22 Parasitic 8. The parasitic element 8 can be disposed on the substrate 1 and connected (coupled) to the bridge 7. At the same time, the parasitic element 8 can be connected (coupled) to the grounding element 4 and do not overlap with the second radiating portion 22. In this way, the parasitic element 8 can be used to adjust the impedance value corresponding to the center frequency of the second operating band and the frequency range of the second operating band.

Next, in detail, the parasitic element 8 may include a first parasitic portion 81 connected to the second side end 72 of the bridge 7 and a second parasitic portion 82 connected to the first parasitic portion 81. For example, the first parasitic portion 81 may extend in a fourth direction (positive Y direction) close to the second radiating portion 22, and the second parasitic portion 82 may extend in a second direction (positive X direction) away from the coupling member 3 , And the extending direction of the second parasitic portion 82 is substantially parallel to the extending direction of the second radiating portion 22. In addition, from the top view, there is a predetermined slit W between the second parasitic portion 82 of the parasitic element 8 and the second radiating portion 22, when the second parasitic portion 82 of the parasitic element 8 is horizontal to the second radiating portion 22 The smaller the offset distance (or predetermined slit W, that is, the distance between the second parasitic portion 82 and the second radiating portion 22 of the parasitic member 8), the more the impedance value corresponding to the center frequency of the second operating band Close to a preset impedance value. When the impedance value is closer to the preset impedance value, the value of the voltage standing wave ratio corresponding to the center frequency of the operating frequency band is closer to 1.

Furthermore, the extension length of the parasitic element 8 is inversely proportional to the size of the frequency range of the second operating band generated by the antenna structure Q5. In other words, the extension of the parasitic element 8 The smaller the length, the higher the frequency range of the operating band generated by the antenna structure Q5. For example, the extension length of the parasitic member 8 may be the sum of a first length L1' of the first parasitic portion 81 and a second length L2' of the second parasitic portion 82. Wherein, the first length L1' can be counted from the connection between the parasitic member 8 and the bridge 7 to the edge of the second parasitic portion 82, and the second length L2' can be counted from the edge of the first parasitic portion 81 to the first The end of the second parasitic portion 82.

It is worth noting that although the parasitic element 8 is connected to the bridge 7 in the fifth embodiment, in other embodiments, the bridge 7 (not shown in the figure) may not be provided, and The grounding element 4 is directly electrically connected to the parasitic element 8, and the parasitic element 8 is disposed adjacent to the second radiating portion 22 without overlapping with the second radiating portion 22, that is, the parasitic element 8 is positive on the XY plane The projection and the orthographic projection of the second radiation section 22 on the XY plane do not overlap each other.

In other words, as the degree of coupling is smaller or the distance of the coupling gap G is larger, the frequency range of the operating band generated by the antenna structure Q6 will decrease, and the center frequency of the operating band generated by the antenna structure Q6 will increase.

First, please refer to FIG. 20 and FIG. 21, FIG. 20 is a top perspective schematic view of an antenna system according to a thirteenth embodiment of the present invention. 21 is a functional block diagram of an antenna system according to a thirteenth embodiment of the present invention. From the comparison between FIG. 20 and FIG. 1, the biggest difference between the thirteenth embodiment and the first embodiment is that the antenna system T provided in the thirteenth embodiment can use the antenna structure (Q1, Q2 provided in the previous embodiment , Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q10, Q11, Q12) and used in conjunction with a proximity sensing module (proximity sensing circuit) P1 and an inductor P2. It should be noted that, for ease of description, the antenna structure in the antenna system T is described using the antenna structure Q1 provided in the first embodiment. In this way, through the arrangement of the proximity sensing module P1 and the inductor P2, the antenna structure Q1 can have a function of sensing whether the human body is close to the antenna system T, thereby adjusting the transmission power of the antenna structure Q1. In addition, for example, the antenna system T can be applied Two-in-one notebook computers (Hybrid laptops or 2-in-1 laptops), but the invention is not limited thereto.

In detail, the inductor P2 may be electrically connected between the radiating element 2 and the proximity sensing module P1, and the proximity sensing module P1 may be electrically connected between the inductor P2 and the grounding element 4. In other words, the proximity sensing module P1 and the inductor P2 can be disposed on the substrate 1 and electrically connected between the radiating element 2 and the metal conductor E, or between the radiating element 2 and the grounding element 4 to form a Conductive circuit. For example, the inductor P2 may be a low-pass filter, and the proximity sensing module P1 may be a capacitance sensor, which is configured by the capacitance sensor and the low-pass filter Afterwards, the radiating element 2 of the antenna structure Q1 can be used as a sensing electrode for the proximity sensing module P1 to measure the capacitance value.

In this way, since the radiating element 2 is disposed at the outer layer of the electronic device, and the radiating element 2 is used as the sensing electrode in proximity to the sensing module P1, the sensing distance of the antenna structure Q1 can be far. However, since a first distance D1 between the upper surface of the display panel N and the upper surface of the radiating element 2 is relatively long, the radiating element 2 will be blocked by the display panel N and the antenna efficiency will be reduced.

In the fifteenth embodiment, The coupling element 3, the substrate 1 and the radiating element 2 are sequentially stacked and arranged on the back cover structure C, so that the coupling element 3 is closer to the back cover structure C than the radiating element 2. By this, compared to the tenth In the fourth embodiment, since the radiator 2 in the fifteenth embodiment is disposed at the inner layer of the electronic structure, the sensing distance of the antenna structure is relatively short. However, since the upper surface of the display panel N is above the radiator 2 A second distance D2 between the surfaces is closer, therefore, the radiating element 2 will be less likely to be blocked by the display panel N and can improve the antenna efficiency. In other words, by combining the antennas of the first to fifteenth embodiments The radiating element 2 of the structure is arranged at the inner layer position of the electronic structure, which can improve the antenna efficiency.
