The following detailed description of exemplary embodiments of the disclosure refers to the accompanying drawings.
In the history of mobile communication, mobile communication methods such as 1G, 2G, 3G, and 4G have been used in succession. Before the 5G communication is stepped in, the 4G communication mode is mainly used as the main mode, and the 2G communication mode and the 3G communication mode are compatible. That is to say, not only the 5G communication antenna but also the 2G, 3G, 4G communication antenna and the Wifi antenna are generally included in the 5G communication terminal device.
In the communication field, antennas for receiving different signals have different lengths, and the higher the frequency band of a received signal, the shorter the corresponding antenna (approximately 1/4 of the wavelength of the received signal).
At present, communication antennas (such as 2G, 3G, 4G or Wifi antennas) in terminal devices are usually placed at the frame positions of the middle frame of the terminal device (such as a mobile phone).
Assuming that the terminal device is a mobile phone, the middle frame of the terminal device may refer to a middle portion of the housing separating the liquid crystal screen of the mobile phone from the main board. The mobile phone middle frame not only has aesthetic property, but also has strong functionality. If the internal accessories of the mobile phone are compared with the large organs of the human body, the middle frame of the mobile phone is equivalent to the skeleton of the human body, and the large organs can be supported on the nerve of the skeleton to normally operate, namely, all the devices in the mobile phone need to work on the middle frame of the mobile phone.
Fig. 1 is a schematic diagram showing the distribution of different antenna modules in a terminal device according to the related art.
In some embodiments, a communication terminal device generally includes a plurality of antenna units with a length of centimeter or more, and the plurality of antenna units may be disposed at a frame of a middle frame of the terminal device.
As shown in fig. 1, a volume up button 01, a volume down button 02, a power on/off button 03, a first Wifi antenna 04, a first GPS antenna 05, a second Wifi antenna 06, a first main antenna 07 (including but not limited to a 4G antenna, etc.), a second main antenna 08, a second GPS antenna 09, a first sim (subscriber identity module) card socket 10, a second sim card socket 11, a first diversity antenna 12, a second diversity antenna 13, etc. may be disposed at a frame position of a middle frame 00 of the terminal device.
In the related art, since signals generate multipath component signals due to interference such as reflection during transmission, a receiving end receives signals of different paths simultaneously by using an antenna, and then selects and combines the signals into an overall signal to mitigate the influence of signal fading, which is called diversity reception.
In mobile communication technology, diversity antennas may be employed for reception of signals. Diversity antennas are not used to extend the coverage of the radio but to enhance signal coverage in the area to solve problems due to multipath distortion and signal-free spots.
Generally, the main antenna is an antenna capable of transmitting and receiving signals, the diversity antenna can only receive signals, when the signals are transmitted to the cell antenna through uplink, the main antenna and the diversity antenna can simultaneously receive the signals, so that two paths of signals are generated, and then the base station selects a path of best signals to demodulate through the decision device. The reason for this is that for spatial diversity, the same signal is received and processed by two antennas to obtain a best signal.
In some embodiments, the GPS antenna may be used to receive GPS satellite signals and the Wifi antenna may be used to transceive wireless network signals.
It can be understood that the number of each antenna in the terminal device is not limited, and the more the number of antennas is, the more sensitive the terminal device may be to receive the signal of the corresponding frequency (if the number of antennas is transitional, interference may be expected between the antennas, which reduces the sensitivity of receiving the signal).
In addition, in the terminal device, it is not only required to ensure that the antenna device is far away from the metal element, but also to isolate irrelevant components such as a battery, an oscillator, a shielding case, a camera and the like, so as to leave a clean space (clearance for short) for the antenna, and ensure that the antenna can radiate in all directions at 360 degrees. Generally, the radius of the clearance area of the antenna is ensured to be greater than or equal to half of the length of the corresponding antenna.
Therefore, placing an antenna in a terminal device may have the following problems: 1. when the antenna is arranged on the left frame and the right frame of the middle frame, the antenna can be shielded when the terminal is held by a hand, and antenna signals are attenuated. 2. With the advent of 5G technology, the number of antennas increases, and if 5G antennas are disposed on the border of the middle frame of the terminal device, the clearance area required by the antennas will be challenged, and the interference between the antennas will be more serious, so it is highly desirable to dig a proper position in the terminal device for placing the antennas.
Fig. 2 is a schematic structural view of a 4G antenna shown according to the related art.
As shown in fig. 2, the antenna of the 4G network may include the following devices: a baseband 201, a radio frequency chip 202, a Power Amplifier (PA) 203, a filter 204, an antenna switch 205, antennas 206, 207, 208, 209, a Low Noise Amplifier (LNA) 210, and a filter 211.
It is understood that the number of antennas in the 4G antenna is not limited by the present disclosure, subject to the actual needs of the designer.
In some embodiments, the antennas 206, 207, 208, 209 may be used to convert electromagnetic waves transmitted from the base station into weak alternating current signals during signal reception, or convert alternating current into electromagnetic wave signals during signal transmission.
In some embodiments, the antenna switch 205 may perform switching between signal receiving and transmitting functions.
In some embodiments, the filters 204, 211 may be used to filter out unwanted signals to obtain a pure received or transmitted signal.
In some embodiments, the low noise amplifier 210 may amplify a weak current sensed by the antenna to meet a signal amplitude requirement of a subsequent circuit.
In some embodiments, the power amplifier 203 may amplify the signal to obtain a current with sufficient power, and the current may be converted into electromagnetic waves via the antennas 206, 207, 208, 209 to be radiated out, so as to complete the transmission of the signal.
In some embodiments, when the terminal device (e.g., a mobile phone) receives a signal, the antennas 206, 207, 208, and 209 may convert an electromagnetic wave transmitted by a base station into a weak ac signal, and the weak ac signal flows into the low noise amplifier 210, the filter 211, the rf chip 202, and the baseband 201 through the antenna switch 205, so that the terminal device receives a base station signal.
Similarly, the working principle of the terminal device for receiving signals can be understood, and the details of the disclosure are omitted.
Currently, because the frequency of signals that can be transmitted and received by a 4G antenna is low (generally less than 3 GHz), the size of the 4G antenna is large (generally centimeter-sized length). Therefore, the 4G antenna is not generally placed at the edge of the screen of the terminal device for the sake of the aesthetic appearance of the terminal device (of course, the 4G antenna or other antennas may be placed at the edge of the screen of the terminal device if necessary).
Similarly, since the frequency bands of signals received by the antennas such as 2G, 3G, wifi and the like are low, the lengths of the antennas are all in centimeter level.
With the development of the technology, the 5G communication technology is gradually matured. The 5G network is used as a fifth generation mobile communication technology, the highest theoretical transmission speed can reach 10Gb per second, which is hundreds of times faster than the transmission speed of the current 4G network; due to the characteristics of high speed, low time delay and low power consumption, the system can penetrate into the Internet of things and various industries in the future, is deeply integrated with industrial facilities, medical instruments, transportation tools and the like, and effectively meets the diversified service requirements of the vertical industries such as industry, medical treatment, transportation and the like.
In the 5G communication technology, the 5G antenna technology plays a crucial role.
According to the specification of the 3gpp 38.101 protocol (the 3gpp 38.101 protocol specifies the operating band of 5G), the 5G NR (5G New Radio, global 5G standard) mainly uses two bands of frequencies: the FR1 frequency band and the FR2 frequency band. The frequency range of the FR1 frequency band is 450MHz-6GHz (Hertz), also called sub 6GHz frequency band; the frequency range of the FR2 band is 24.25GHz-52.6GHz, which is commonly called millimeter Wave (mmWave).
It will be appreciated that antennas of different lengths may receive signals in different frequency bands. That is, the frequency bands of the signals are different, and the lengths of the antennas receiving the signals should be different accordingly.
For the 5G antenna receiving the FR1 frequency band signal, because the frequency band of the signal received by the antenna is not much different from the frequency band of the signal received by the 4G antenna, and the corresponding antenna length is also in the centimeter level, the design of the 4G antenna can be adopted for the 5G antenna receiving the FR1 frequency band signal; for the 5G antenna for receiving the FR2 frequency band signal, since the frequency range of the signal that can be received by the antenna is 24.25GHz-52.6GHz, the length of the antenna corresponding to the antenna is millimeter-scale, and therefore the 5G antenna suitable for placing the received FR2 frequency band signal is to be found in the terminal device.
Fig. 3 is a schematic diagram illustrating lengths of antennas for a different communication approach, according to an example embodiment.
As shown in fig. 3, the lengths of the antennas corresponding to the communication modes such as 2G, 3G, 4G, bluetooth, GPS, and beidou are all in the order of centimeters, that is, the lengths of the antennas required by the communication modes are all greater than 1 centimeter.
For 5G communication, since the 5G communication includes two different frequency bands, the 5G antenna needs to be discussed in two cases. Wherein, for an FR1 signal (for example, a signal of 3-5 GHz), the length of a 5G antenna receiving the FR1 signal is relatively long, and is generally 1.5-2.5 cm; for FR2 signals (e.g., 20-30GHz signals), the length of the antenna receiving the FR2 signal is relatively short, typically on the order of 2.5 millimeters. It follows that for an antenna receiving FR2 (which may also be referred to as millimeter wave), its length may have been reduced from the centimeter level of a 4G antenna to the millimeter level.
In some embodiments, for 5G low-frequency signals in the FR1 frequency band, because the antenna is long, the shape of the antenna is basically consistent with that of the antenna in the existing cellular network, so that the antenna can be completely integrated with the antenna in the existing cellular network. However, for 5G high frequency signals (up to 30 GHz) in the FR2 band, since the antenna configuration is basically different from the prior art, this means that several antenna modules are added to the terminal device. In the related art, due to the limited space of the terminal device, the millimeter wave antenna (antenna for receiving FR2 band signals) is usually disposed at the frame position of the middle frame of the terminal device and at the back of the terminal device. In daily use, the millimeter wave antenna on the back of the terminal device is shielded by the body, so that contribution is limited, and the antenna on the frame of the middle frame of the terminal device is shielded by the hand, so that signals are weak.
Therefore, the antenna module can find a suitable position for placing the millimeter wave antenna and can solve the problem of low sensitivity of transmitting and receiving signals of the antenna.
Fig. 4 is a schematic structural diagram of a 5G communication antenna according to an exemplary embodiment.
As shown in fig. 4, the 5G antenna may include a baseband 401, a radio frequency chip 402, and millimeter wave antenna modules 403, 404, 405, 406. The millimeter wave antenna module can be used for receiving signals in an FR2 frequency band in 5G communication.
In some embodiments, the baseband 401 may be configured to process digital signals, the rf chip 402 may be configured to modulate digital signals into higher-quality video signals or demodulate rf signals into digital signals, and the millimeter wave antenna module may perform receiving and transmitting of 5G signals.
In some embodiments, the baseband 401 and the rf signal 402 may communicate with each other through digital signals (Qlink protocol (Qlink is a distributed worldwide Wifi shared network)), and the rf chip 402 and the millimeter antenna module may communicate with each other through intermediate frequency signals.
It is understood that the number of millimeter wave antenna modules in the 5G communication antenna is not limited by the present disclosure.
Fig. 5 is a schematic structural diagram illustrating a millimeter wave antenna module according to an exemplary embodiment.
As shown in fig. 5, the millimeter wave antenna module includes a radio frequency chip 501, a power amplifier 502, a filter 503, an antenna array 504, a low noise amplifier 505, and a filter 506.
In some embodiments, the rf chip 501 may be used to modulate and demodulate the intermediate frequency signal transmitted by the rf chip 402 in fig. 1 to a high frequency.
In some embodiments, the power amplifier 502 may amplify the signal to obtain a current of sufficient power.
In some embodiments, the filters 503, 506 may be used to filter out unwanted signals to obtain a pure received or transmitted signal.
In some embodiments, the low noise amplifier 505 may amplify the weak current sensed by the antenna array to meet the signal amplitude requirement of the subsequent circuit.
In some embodiments, the antenna array 504 can be used to convert electromagnetic waves transmitted from a base station into weak alternating current signals during signal reception, and can also be used to convert alternating current into electromagnetic wave signals during signal transmission.
In some embodiments, the antenna array 504 may be, for example, a phased antenna array.
In the communication field, because the directivity of a single antenna is limited, in order to be suitable for various applications, two or more single antennas operating at the same frequency are generally required to be fed and spatially arranged according to certain requirements to form an antenna array.
Phased antenna arrays have been developed from antenna arrays, which mainly rely on phase changes to achieve spatial movement or scanning of the antenna beam pointing, also known as electronically scanned array antennas.
A phased antenna array may refer to an antenna that changes a pattern shape by controlling a feeding phase of a radiation element in an array antenna. The control phase can change the direction of the maximum value of the antenna pattern so as to achieve the purpose of beam scanning.
In a special case, the side lobe level, the minimum position, and the shape of the entire directional diagram may be controlled, for example, a cotangent square directional diagram is obtained, and the directional diagram is adaptively controlled. When the antenna is rotated by a mechanical method, the inertia is large, the speed is low, the phased antenna array overcomes the defect, and the scanning speed of the wave beam is high. Its feeding phase is controlled by computer, and its phase change speed is quick (millisecond order), i.e. the maximum directivity of antenna pattern or other parameters can be quickly changed. This is the biggest feature of phased antenna arrays.
Fig. 6 is a schematic structural diagram of a terminal device including an antenna module according to an exemplary embodiment. The display screen of the terminal device is described as a quadrangle, and the display screen of the terminal device may also be in other shapes such as a circle and a diamond, which is not limited by the disclosure.
As shown in fig. 6, the display screen of the terminal device may include a screen edge, such as a first screen edge 101, a second screen edge 102, a third screen edge 103, or a fourth screen edge 104.
In some embodiments, the screen edge of the display screen may be a display screen at the edge, or may be a portion externally connected to the edge of the display screen, which is not limited in this disclosure.
In some embodiments, the antenna module may include an antenna array module 105, and the antennas in the antenna array module 105 have a length of millimeter or less. That is, the antenna array may receive the FR2 signal or a signal having a higher frequency than the FR2 signal among the 5G signals.
In some embodiments, the antenna array module 105 may be an antenna array, for example, may be a phased antenna array.
In some embodiments, the antenna array module 105 may, for example, include at least 4 antenna elements.
In some embodiments, the antenna array module 105 may be integrated at least one screen edge of a display screen of the terminal device.
For example, the antenna array module 105 may be integrated on one or more of the first screen edge 101, the second screen edge 102, the third screen edge 103, or the fourth screen edge 104. At least one antenna array module 105 may be integrated on each frame, which is not limited by the present disclosure.
It is understood that the antenna array module may also be integrated at least one screen edge of the display screen of the terminal device, if the display screen of the terminal device is circular or other shape.
Because the antenna length in the antenna array module 105 is only millimeter-sized or less, the millimeter-wave antenna can be placed only by adding a narrow frame on the display screen of the terminal device or adding a narrow frame around the display screen of the terminal.
In some embodiments, the antenna module may include not only an antenna array module (e.g., a phased antenna array), but also an antenna module device (including a radio frequency chip, a power amplifier, a filter low noise amplifier, etc. as shown in fig. 5).
It is to be understood that the present disclosure is not limited to the placement of other devices in the antenna module other than the phased antenna array.
In some embodiments, the antenna module device may be integrated with the antenna array module 105 at least one edge of a display screen of the terminal device, and the antenna module device may be further integrated on a flexible Printed Circuit Board (PCB) strip connected to the antenna array module 105, and the PCB strip may be bent toward the back of the display screen.
It can be understood that because terminal equipment's display screen can not receive and shelter from in communication process, so put antenna module's antenna array module in at least one screen edge of terminal equipment's display screen not only found a position that is fit for laying the antenna in the terminal equipment, can also improve the sensitivity of antenna send-receive signal.
Fig. 7 is a schematic structural diagram illustrating another antenna module according to an exemplary embodiment.
In some embodiments, the antenna module may be split into two parts as shown in fig. 7, for example, the antenna module is split into an antenna array module 604 (e.g., a phased antenna array) and an antenna module device 600, where the antenna module device 600 may include a radio frequency chip 601, a power amplifier 602, a filter 603, a low noise amplifier 605, a filter 606, and the like.
Fig. 8 is a schematic structural diagram illustrating a terminal device including an antenna module according to an exemplary embodiment.
In some embodiments, the display screen of the terminal device may include a first screen edge 101, a second screen edge 102, a third screen edge 103, and a fourth screen edge 104.
In some embodiments, the first screen edge may be a screen edge of a camera module near the terminal. For a mobile phone terminal, the edge of the screen of the camera module close to the terminal may refer to the upper edge of the mobile phone.
In some embodiments, the antenna module may include a first antenna module 106, the first antenna module 106 may include a first antenna array module 1061, and the first antenna array module 1061 may be integrated at the first screen edge 101.
In the related art, more and more mobile phones consider the problem of tone quality, and loudspeaker sound cavities are formed in the upper side and the lower side of the mobile phone, which is not a comprehensive screen in the traditional sense. Therefore, the antenna array module is arranged at the upper edge of the display screen of the mobile phone, so that the problems of antenna arrangement and signal receiving and transmitting sensitivity are solved, and the attractiveness of the screen is not influenced.
In some other embodiments, the first antenna array module 1061 may include n transmitting modules and n receiving modules, where n is a positive integer greater than or equal to 4.
For example, the first antenna array module may include 4 transmitting modules and 4 receiving modules, or may include 5 transmitting modules and then 5 receiving modules.
It can be understood that, compared with the method of using 3 (or less) transmitting modules and 3 (or less) receiving modules to transmit and receive signals, the method of using 4 (or more) transmitting modules and 4 (or more) receiving modules to transmit and receive signals can improve the data transmission speed.
In some embodiments, the first antenna module 106 may include not only the antenna array module 1061, but also the antenna module device 1062.
As shown in fig. 8, the antenna array module 1061 may be disposed at an edge of at least one screen of a display screen of the terminal device, and the antenna module device 1062 may be disposed on a line board of the terminal device to implement connection with the antenna array module, where the line board is a high-frequency signal transmission medium.
