The radiating portion 41 may enclose a hollow region 42, the radiating portion 41 may include a first radiating region 411 and a second radiating region 412, where the first radiating region 411 and the second radiating region 412 are arranged on the radiating portion 41 at intervals, the first radiating region 411 may be used for radiating signals of a first frequency Band, the second radiating region 412 may be used for radiating signals of a second frequency Band, the first frequency Band is different from the second frequency Band, and the first frequency Band and the second frequency Band both belong to an Ultra Wide (UWB) frequency Band; the hollow area 42 is hollowed out on the radiator 4, and the reasonable arrangement of the feed point 43 and the grounding point 44 is matched, so that the current path of the radiating part 41 when radiating the first frequency band signal and the current path of the radiating part when radiating the second frequency band signal can be adjusted, the positions of the current strong point and the current weak point on the current path are different, the purpose of realizing double-frequency resonance of the radiator 4 can be achieved, compared with the scheme of realizing double-frequency radiation by arranging a row of grounding through holes on the same radiator as a separation wall and further carrying out power distribution by means of a power division feed structure in the related art, the current path can be adjusted by adjusting the structure of the radiator 4, the separation wall and the power division feed structure in the related art are avoided while the double-frequency resonance is achieved, the feed structure is simplified, and the impedance mismatch risk caused by the processing error of the power division feed structure can be reduced.
Further, in order to protect the radiator 4, the antenna structure 100 may further include a protective layer 5, where the protective layer 5 is disposed on a side of the dielectric substrate 2 away from the ground layer 1, and the protective layer 5 may cover the radiator 4 to reduce scratch on the radiator 4. The protective layer 5 may comprise an insulating layer, for example a plastic film, avoiding the influence of the radiation of the radiator 4. In the above embodiment, the dielectric substrate 2 may include the first dielectric substrate 21 and the second dielectric substrate 22, the feeder line 3 may be disposed between the first dielectric substrate 21 and the second dielectric substrate 22, the radiator 4 may be disposed on the surface of the first dielectric substrate 21, the second dielectric substrate 22 may be connected to the ground layer 1, a through hole (not shown) may be disposed on the first dielectric substrate 21, the feeder point 43 and the feeder line 3 may be conducted through a conductive member disposed in the through hole, and the first dielectric substrate 21 and the second dielectric substrate 22 may be bonded and fixed, so that the feeder line 3 may be prevented from being exposed. The first dielectric substrate 21 and the second dielectric substrate 22 may include liquid crystal polymer substrates, and signal loss in the first frequency band and the second frequency band may be reduced by using the characteristics of the liquid crystal polymer substrates that have high frequency and low loss.
Currently, according to the regulations of the federal communications commission in the united states, the UWB band can cover a frequency range of 3.1GHz-10.6GHz, the minimum operating bandwidth is 500MHz, the center frequency of the UWB band currently prevailing in China is 6.5GHz and 8GHz, the bandwidth is above 500MHz, and the UWB band works on a fifth channel and a ninth channel divided by UWB channels, wherein the frequency band of the fifth channel is 6.25GHz-6.75GHz, and the frequency band of the ninth channel is 7.75GHz-8.25GHz. Therefore, by adjusting the size and shape of the radiator 4, the center frequency of the first frequency band can be 6.5GHz, the range of the first frequency band is 6.25GHz-6.75GHz, the center frequency of the second frequency band is 8GHz, and the range of the second frequency band is 7.75GHz-8.25GHz, so as to realize the coverage of the antenna structure 100 on the mainstream UWB frequency band.
For example, in the embodiment provided in the disclosure, the radiator 4 may be disposed in a rectangular shape, the hollow area 42 may also be disposed in a rectangular shape, the first radiation area 411 and the second radiation area 412 may be located at corners of the radiation portion 41, the corners of the first radiation area 411 and the corners of the second radiation area 412 may be disposed adjacent, the feed point 43 may be located at corners of the radiation portion 41 connected to the second radiation area 412 and far from a middle edge of the first radiation area 411, and the ground point 44 may be located at corners of the second radiation area 412 diagonally. Taking the embodiment shown in fig. 4 as an example, the first radiation area 411 may be located at the upper left corner of the radiator 4, the second radiation area 412 may be located at the upper right corner of the radiator 4, the feed point 43 is located at the middle area of the left edge of the radiation portion 41, and the ground point 44 is located at the small left corner, so that the effective current path length of the first radiation area 411 is greater than the effective current path length of the second radiation area 412, and the effective current path length is inversely proportional to the radiation frequency, and thus the frequency of the first frequency band radiated by the radiation portion 41 will be smaller than the frequency of the second frequency band.
Based on the antenna structure 100 provided in fig. 4, simulation is performed by using the center frequency of the first frequency band of 6.5GHz, the range of the first frequency band of 6.25GHz-6.75GHz, the center frequency of the second frequency band of 8GHz, and the range of the second frequency band of 7.75GHz-8.25GHz, as can be seen from the S parameter curve shown in fig. 5, the antenna structure can cover the frequency bands, and as can be seen from the antenna efficiency curve shown in fig. 6, the antenna efficiency reaches-8.35 dB at 6.5GHz, and the antenna efficiency reaches-7.38 dB at 8GHz, thereby meeting the communication requirement of the antenna structure 100. Further, based on the simulation, a correlation simulation map at a center frequency of 6.5Ghz shown in fig. 7 to 9 and a correlation simulation map at a center frequency of 8Ghz shown in fig. 10 to 12 can be obtained.
According to the far-field radiation patterns shown in fig. 7 and 10, it can be seen that in the plane where the radiator 4 faces away from the dielectric substrate 2, the first radiation area 411 and the second radiation area 412 can achieve good omnidirectional radiation, which is beneficial to improving the radiation efficiency of the antenna structure 100; according to the electric field distribution diagrams shown in fig. 8 and 11, the electric field of the first radiation area 411 is strongest at 6.5GHz, so that the first radiation area 411 is the main radiation area for radiating signals in the first frequency band, and the electric field of the second radiation area 412 is strongest at 8GHz, so that the second radiation area 412 is the main radiation area for radiating signals in the second frequency band. According to the current distribution diagrams shown in fig. 9 and 12, at 6.5GHz, the current strong point is located near the grounding point 44, and the current direction is from left to right and from top to bottom, forming a current weak point located in the first radiation area 411; at 8GHz, the current strong point is located near the feed point 43, and the current direction is from bottom to top to form a current weak point located in the second radiation area 412, which means that at 6.5GHz and 8GHz, the current strong point and the current weak point on the current path are different, and the direction of the current path is also different, so that the mutual interference between resonances in different frequency bands can be reduced while dual-frequency resonance is realized.
It will be appreciated that when the antenna structure 100 is applied to different electronic devices, a certain frequency offset may be caused to the antenna structure 100 due to different environments in the electronic devices. Therefore, as shown in fig. 4, the first radiation area 411 may include a first step 413, and the second radiation area 412 may include a second step 414, and the current path at 6.5GHz may be limited by the first step 413, and the effective length of the current path at 6.5GHz may be adjusted, so as to avoid frequency offset due to the environment in the electronic device; similarly, the second step 414 can limit the current path at 8GHz and adjust the effective length of the current path at 8GHz, thereby avoiding frequency offset due to the environment within the electronic device.
The first step 413 and the second step 414 are located at adjacent both side edges on the radiating portion 41, for example, as shown in fig. 4, the first step 413 is located at the right side edge of the radiating portion 41, and the second step 414 is located at the upper side edge of the radiating portion 41. With this, the influence on the current path at 8GHz can be reduced while the first step 413 restricts the current path at 6.5GHz, which is advantageous for realizing independent adjustment of the first frequency band and the second frequency band. In the technical solution of the present disclosure, the first radiation area 411 includes the first step portion 413, and the second radiation area 412 includes the second step portion 414, and in other embodiments, the first radiation area 411 may include the first step portion 413 or the second radiation area 412 may include the second step portion 414, which is not limited in this disclosure. In the above embodiments, the center frequency of the first frequency band is 6.5GHz, and the center frequency of the second frequency band is 8GHz, which is not limited in this disclosure, although the center frequency of the first frequency band may be the center frequency of other channels of the UWB frequency band and the center frequency of the second frequency band may be the center frequency of other channels of the UWB frequency band by reasonable setting.
Still taking the embodiment shown in fig. 4 as an example, the width of the edge of the radiating portion 41 between the first radiating area 411 and the second radiating area 412 is smaller than the width of the opposite side edge. That is, as shown in fig. 4, the width dimension of the upper edge in the up-down direction is smaller than the width dimension of the lower edge in the up-down direction, so that the amount of current on the edge between the first radiation area 411 and the second radiation area 412 can be reduced, which is advantageous in reducing interference between the signals in the first frequency band and the signals in the second frequency band. Still referring to fig. 4, taking the first frequency band having a center frequency of 6.5GHz, the first frequency band having a range of 6.25GHz-6.75GHz, the second frequency band having a center frequency of 8GHz, the second frequency band having a range of 7.75GHz-8.25GHz as an example, the radiator 4 may have a length of 11.56 mm and a width of 9.35mm, and the edge between the first radiation area 411 and the second radiation area 412 may be disposed along the length direction of the radiation portion 41.
Based on the various embodiments described above, the present disclosure also provides an electronic device that may include the antenna structure 100 described in any of the embodiments described above. The antenna structure 100 is configured for the electronic device, so that indoor positioning of the electronic device is facilitated, and the defect of positioning difference of a GPS positioning system in a relatively closed environment can be overcome.
