Please refer to FIG. 2, which is a circuit block diagram of a user terminal device provided by an implementation manner of the application. The user terminal device 1 includes multiple radio frequency front-end modules 310, multiple interfaces 320, multiple switching modules 330, K antenna groups 21a, and a processor 130. The multiple radio frequency front-end modules 310 are used to send and receive radio frequency signals. The interface 320 is electrically connected to the radio frequency front-end module 310, and different interfaces 320 are electrically connected to different radio frequency front-end modules 310. One switching module 330 is electrically connected to one interface 320, and different switching modules 330 are connected to different interfaces 320. Each antenna group 21a includes J first signal receiving antennas 210, and the J first signal receiving antennas 210 in each antenna group 21a are electrically connected to the radio frequency front-end module 310 through a switching module 330 and an interface 320, And different antenna groups 21a are electrically connected to different interfaces 320 and different switching modules 330, and the switching module 330 is used to implement each first signal in the J first signal receiving antennas 210 in one antenna group 21a The receiving antenna 210 is separately electrically connected to the radio frequency front-end module 310 and forms a conductive path. The switching module 330 is also used to switch between different conductive paths, where J is a positive integer greater than one. The processor 130 is configured to select N first signal receiving antennas 210 from the K*J first signal receiving antennas 210 when the first signal receiving antenna 210 receives and transmits radio frequency signals, so as to implement N*N channels. The reception and transmission of radio frequency signals.

The first signal receiving antenna 210 may be, but not limited to, a millimeter wave signal receiving antenna or a terahertz signal receiving antenna. Correspondingly, the first network signal may be, but not limited to, a millimeter wave signal or a terahertz signal. At present, in the 5th generation wireless systems (5G), according to the 3GPP TS 38.101 agreement, 5G new radio (NR) mainly uses two frequency bands: FR1 frequency band and FR2 frequency band. Among them, the frequency range of the FR1 frequency band is 450MHz to 6GHz, which is also called the sub-6GHz frequency band; the frequency range of the FR2 frequency band is 24.25GHz to 52.6GHz, which belongs to the millimeter wave (mm Wave) frequency band. The 3GPP Release 15 version regulates the current 5G millimeter wave frequency bands including: n257 (26.5-29.5GHz), n258 (24.25-27.5GHz), n261 (27.5-28.35GHz) and n260 (37-40GHz).

Specifically, the switching module 330 may work under the control of the processor 130. Under the control of the processor 130, the switching module 330 can only enable one of the J first signal receiving antennas 210 in the antenna group 21a corresponding to the switching module 330 at one point in time. 210 is electrically connected to the radio frequency front-end module 310, so that a conductive path is formed between the first signal receiving antenna 210 and the radio frequency front-end module 310; The conductive path of the radio frequency signal is sent and received. Further, the switching module 330 is further configured to switch the first signal receiving antenna 210 connected to the radio frequency front-end module 310 to another first signal in the same antenna group 21a under the control of the processor 130 The receiving antenna 210 is used to switch the conductive path between the radio frequency front-end module 310 and the first signal receiving head antenna. Since the switching module 330 realizes that each of the J first signal receiving antennas 210 in the same antenna group 21a is individually connected to the radio frequency front-end module 310 and forms a conductive path, the processor 130 When N first signal receiving antennas 210 are selected from K*J first signal receiving antennas 210 to realize the reception and transmission of N*N radio frequency signals, the selected N first signal receiving antennas 210 belong to Different antenna groups 21a.

Select N first signal receiving antennas 210 from K*J first signal receiving antennas 210 to realize the reception and transmission of N*N radio frequency signals. At this time, the selected N first signal receiving antennas 210 It forms a Multiple-Input Multiple-Output (MIMO) antenna. When the selected N first signal receiving antennas 210 constitute a MIMO antenna, the communication quality of the user terminal device 1 using the first signal receiving antenna 210 to transmit and receive the first network signal can be improved.

In the schematic diagram of this embodiment, the number of the interfaces 320 is 4, the number of the switching modules 330 is 4, the K antenna groups 21a are 4 antenna groups 21a, and J first signal receivers The antenna 210 is two first signal receiving antennas 210 as an example for illustration. At this time, the switching module 330 may be, but not limited to, a single-pole double-throw switch. For ease of description, the four interfaces 320 are named interface 320a, interface 320b, interface 320c, and interface 320d, respectively. The four switching modules 330 are respectively named as the switching module 330a, the switching module 330b, the switching module 330c, and the switching module 330d. The four antenna groups 21a are respectively named antenna group ①, antenna group ②, antenna group ③, and antenna group ④.

In this embodiment, each first signal receiving antenna 210 in each antenna group 21a can form an independent path between the switching module 330 and the interface 320 and the radio frequency front-end module 310. In this case, The radio frequency front-end module 310 can transmit and receive radio frequency signals through the first signal receiving antenna 210 that forms a path with the radio frequency front-end module 310, thereby ensuring that the radio frequency front-end module 310 transmits radio frequency signals through the first signal receiving antenna 210. Compared with the multiple first signal receiving antennas 210 that are combined into one channel for radio frequency signal transmission and reception, the independence of the transmission and reception path is smaller. The attenuation of the radio frequency signal when the radio frequency signal is transmitted and received in this embodiment is smaller, which is beneficial to improve the performance of the radio frequency signal. The communication quality of the user terminal device 1 is described. Further, in the present application, by using the switching module 330 to electrically connect the J first signal receiving antennas 210 in one antenna group 21a to the same interface 320 and electrically connect to the radio frequency front-end module 310 through the same interface 320, it can ensure that the antenna group 21a The consistency of the radio frequency signals sent and received by the J first signal receiving antennas 210 received by the radio frequency front-end module 310 is beneficial to subsequent data processing. If the J first signal receiving antennas 210 in an antenna group 21a are all electrically connected to the radio frequency front-end module 310 through different interfaces 320, due to various factors, for example, the interface 320 or the radio frequency front-end module 310 electrically connected to the interface 320 is being prepared. In case of preparation errors, etc., the consistency of the RF signals output by the RF front-end module 310 through different interfaces 320 is not good, which is not conducive to subsequent data processing. In addition, in the present application, the J first signal receiving antennas 210 in one antenna group 21a are electrically connected to one interface 320 through the switching module 330, which can reduce the number of interfaces 320 and facilitate the integration of the user terminal device 1.

Please refer to FIG. 3, which is a circuit block diagram of a user terminal device provided by an implementation manner of the application. In an embodiment, the user terminal device 1 further includes a radio frequency transceiver 340. The user terminal device 1 including the radio frequency transceiver 340 can be incorporated into the user terminal device described in FIG. 2 and its related description. The radio frequency transceiver 340 is electrically connected to the plurality of radio frequency front-end modules 310. When the J first signal receiving antennas in the K antenna groups are used to receive the first network signal, the radio frequency transceiver 340 receives the radio frequency signal output by the radio frequency front-end module 310, and combines the received radio frequency signal Convert to baseband signal.

In an embodiment, the K antenna groups 21a are 4 antenna groups 21a, the J first signal receiving antennas 210 are two first signal receiving antennas 210, and the N*N channels are 4* 4 channels, the two first signal receiving antennas 210 in the same antenna group 21a receive the first network signal in different directions, and the two first signal receiving antennas 210 in the same antenna group 21a have different polarization directions.

In addition, when the first network signal transmitted by the base station 3 is propagated to the user terminal device 1, due to various reasons such as scattering, the first network signal exhibits an elliptical polarization. Generally, the first signal receiving antenna 210 in one polarization direction cannot receive all the energy of the first network signal, and even the energy of the first network signal received by the first signal receiving antenna 210 in a certain polarization direction is very small. The polarization directions of the J first signal receiving antennas 210 in an antenna group 21a of the present application are different, which can improve the larger energy first network signal received by the J first signal receiving antennas 210 in the antenna group 21a. Probability.

In some embodiments, J=2, that is, one antenna group 21a includes two first signal receiving antennas 210, one of the two first signal receiving antennas 210 in the same antenna group 21a The polarization direction of is the first polarization direction, and the polarization direction of the other first signal receiving antenna 210 of the two first signal receiving antennas 210 in the same antenna group 21a is the second polarization direction, where The first polarization direction and the second polarization direction are respectively ±45° polarization directions.

As described above, when the first network signal transmitted by the base station 3 is propagated to the user terminal device 1, due to various reasons such as scattering, the first network signal exhibits an elliptical polarization. A single horizontally polarized or vertically polarized first signal receiving antenna 210 cannot receive all the energy. In order to receive as much energy of the first network signal as possible, two first signal receiving antennas 210 whose polarization directions are perpendicular to each other are arranged in an antenna group 21a to receive the first network signal. It is ensured that the energy of the first network signal can be received in the antenna group 21a at any time. However, the first network signal of vertical polarization or horizontal polarization will become the first network signal of elliptical polarization during the transmission process, and the components of the first network signal of elliptical polarization in the vertical direction and the horizontal direction are inconsistent. If two first signal receiving antennas 210 with linear polarizations of 0° and 90° are respectively used in the antenna group 21a, most of the first network signals will be received by one of the first signal receiving antennas 210 . Therefore, in order to ensure that the two first signal receiving antennas 210 in the same antenna group 21a can be used effectively, therefore, the two first signal receiving antennas 210 in the same antenna group 21a are respectively set to ±45° polarization, thereby It can be avoided that the two first signal receiving antennas 210 in the same antenna group 21a cannot effectively receive the first network signal. In other words, that the two first signal receiving antennas 210 in the same antenna group 21a are respectively set to ±45° polarization means that one of the first signal receiving antennas 210 in the same antenna group 21a is +45° polarization. The other first signal receiving antenna 210 in the same antenna group 21a is -45° polarization.

Please refer to FIG. 4, FIG. 5, FIG. 6 and FIG. 7. FIG. 4 is a schematic diagram of the structure of a user terminal device provided by an embodiment of this application; FIG. 5 is an embodiment of the user terminal device of FIG. 4 after the housing is removed Fig. 6 is a circuit block diagram of user terminal equipment in another embodiment of this application; Fig. 7 is a schematic diagram of two first signal receiving antennas carried on the same carrier board. The user terminal device 1 includes a housing 220. The shape of the shell 220 may be a multi-faceted cylindrical tube or a cylindrical tube. The material of the housing 220 may be, but is not limited to, an insulating material such as plastic. It can be understood that, in other implementation manners, the user terminal device 1 may also not include the housing 220.

The user terminal equipment 1 including the antenna group 21a further includes a signal conversion device 120. The first signal receiving antenna 210 is used to receive a first network signal, and the signal conversion device 120 is used to convert the first network signal received by the selected first signal receiving antenna 210 into a second network signal.

The first signal receiving antenna 210 millimeter wave or terahertz signal has advantages such as fast transmission speed. However, the millimeter wave or terahertz signal is easily blocked by external objects. When there is an object obstructing the first signal receiving antenna 210 and the base station 3, the signal strength of the first network signal received by the first signal receiving antenna 210 is weaker. At this time, if the signal strength of the first signal receiving antenna 210 is weaker, the signal strength of the first network signal is relatively weak. The conversion of a network signal into a second network signal may result in a weaker signal strength of the obtained second network signal. In this embodiment, the first signal receiving antenna 210 is a sub-6GHz signal receiving antenna as an example for description. Correspondingly, the first network signal is a radio frequency signal in the sub-6GH frequency band, and the second network signal may be, but is not limited to, a WiFi signal.

The K antenna groups 21a may be directly or indirectly arranged on the inner wall of the housing 220, or arranged on other components.

Please refer to FIG. 8. FIG. 8 is a schematic structural diagram of the user terminal device of FIG. 4 after removing the casing in another embodiment. The user terminal device 1 further includes a plurality of bearing boards 211, the plurality of bearing boards 211 are arranged around the user terminal device 1, and each bearing board 211 carries the J (two in this embodiment). One signal receiving antenna 210, and the J first signal receiving antennas 210 carried on the same carrier board 211 belong to different antenna groups 21a.

The carrying board 211 is arranged around the user terminal device 1, and the carrying board 211 can be directly arranged on the inner wall of the housing 220, or fixed on other parts of the user terminal device 1220, such as a circuit board . When the shape of the housing 220 is square, the carrying plate 211 may be arranged on four faces of the housing 220.

In this embodiment, the J first signal receiving antennas 210 in the same antenna group 21a are arranged on different carrier boards 211, so that the J first signal receiving antennas 210 in the same antenna group 21a can receive The first network signal has a wider range. In other words, the J first signal receiving antennas 210 in the same antenna group 21a are arranged on different carrier boards 211, so that the J first signal receiving antennas 210 in the same antenna group 21a receive The quality of the first network signal varies greatly. When the processor 130 controls the switching module 330 to switch between the J first signal receiving antennas 210 in the same antenna group 21a, the quality of the first network signal changes Is larger, which facilitates the rapid adjustment of the quality of the first network signal received by the antenna module by selecting different first signal receiving antennas 210 in the same antenna group 21a, which in turn facilitates the user terminal device 1 working in the first network signal.

In the case of connecting to a preset network, the sum of the signal strengths of the selected first signal receiving antenna 210 is the largest or greater than the preset threshold.

When the sum of the signal strengths of the first network signals received by the selected first signal receiving antenna 210 is maximum or greater than the preset threshold, the signal conversion device 120 receives the network signals received by the selected first signal receiving antenna 210 Converted to the second network signal.

Due to the uncertainty of the location of the base station 3 that transmits the first network signal, the direction of the transmission of the first network signal is also uncertain. The signal strength of the first network signal received by the first signal receiving antenna 210 in each direction is also different. For example, when there is an object blocking the first signal receiving antenna 210 and the base station 3, the signal strength of the first network signal received by the first signal receiving antenna 210 is relatively weak. At this time, if the weaker first network signal is converted to the second network signal, the signal strength of the obtained second network signal will also be weaker. In the user terminal device 1 in the present application, when the sum of the signal strengths of the first network signals received by the selected first signal receiving antenna 210 is the largest or is greater than the preset threshold, the signal conversion device 120 will be the selected first network signal.

The carrying plate 211 is disposed between the carrying plate 211 and the conductive baffle 213 and can support the carrying plate 211.

The supporting plate 214 includes a first supporting portion 2141 and a second supporting portion 2142. The first supporting portion 2141 and the second supporting portion 2142 are arranged to cross each other, and the first supporting portion 2141 includes a first supporting portion 2141 disposed opposite to each other. Surface 214a and second surface 214b. The first surface 214a is provided with a grounding member. For the convenience of description, the grounding member provided on the first surface 214a is named the first grounding member 215, and the first grounding member 215 is used to connect the antennas in the antenna group 21a. The first signal receiving antenna 210 is grounded, and the second surface 214b is provided with a power feeder. For the convenience of description, the power feeder provided on the second surface 214b is named the first power feeder 216. The electrical component 216 is coupled to the first signal receiving antenna 210 for feeding.

The number of the first grounding member 215 is two, that is, the first grounding member 215 includes a first grounding member 215a and a first grounding member 215b. The first grounding member 215a and the first grounding member 215b are both disposed on the first surface 214a and respectively disposed on two opposite sides of the second supporting portion 2142. The first grounding member 215a is used to electrically connect the first receiving portion 2111 of the first signal receiving antenna 210c in the antenna group 21a to the conductive baffle 213. The second grounding member 215b is used to connect the second receiving portion 2113 of the first signal receiving antenna 210c in the antenna group 21a to the conductive baffle 213. The first grounding member 215a and the second grounding member 215b may be, but not limited to, a metal conductive layer, such as a copper layer. Understandably, the first grounding member 215a and the second grounding member 215b may not be provided on the first surface 214a, as long as it satisfies the requirement of electrically connecting the first signal receiving antenna 210 to the conductive baffle 213 is fine.

One end of the first power feeding member 216 adjacent to the conductive baffle 213 is electrically connected to the signal conversion device 120. Specifically, in this embodiment, the first feeder 216 includes a first stub 2161, a second stub 2162, and a third stub 2163 that are sequentially bent and connected, and the first stub 2161 and The third branch 2163 is disposed at opposite ends of the second branch 2162. The first branch 2161 is perpendicular or substantially perpendicular to the supporting plate 211, the second branch 2162 is parallel or substantially parallel to the supporting plate 211, and the third branch 2163 is connected to the first branch. Section 2161 is parallel or substantially parallel. The functions of the first branch 2161, the second branch 2162, and the third branch 2163 are described in detail below.

The first stub 2161 is used to adjust the impedance matching between the signal conversion device 120 and the first signal receiving antenna 210, and the top of the first stub 2161 is away from the first signal receiving antenna 210 The distance of φ determines the coupling efficiency of the first power feeding element 216 and the first signal receiving antenna 210. The first branch 2161 is used to adjust the coupling efficiency and impedance matching between the first signal receiving antenna 210 and the signal conversion device 120. Specifically, when the distance between the top end of the first stub 2161 and the first signal receiving antenna 210 is a preset distance, the distance between the first feeder 216 and the first signal receiving antenna 210 The coupling efficiency is the largest and the impedance matching between the first signal receiving antenna 210 and the signal conversion device 120 is the best. When the top end of the first stub 2161 and the first signal receiving antenna 210 When the distance is greater than the preset distance or less than the preset distance, the coupling efficiency and impedance matching between the first feeder 216 and the first signal receiving antenna 210 will be reduced.

The second branch 2162 is used to adjust the standing wave depth of the first network signal received by the first signal receiving antenna 210. Specifically, the length of the second stub 2162 affects the standing wave depth of the first network signal received by the first signal receiving antenna 210. When the length of the second stub 2162 is equal to the preset length, the first The standing wave depth of the network signal is the deepest. When the length of the second branch 2162 is greater than or less than the preset length, the standing wave depth of the first network signal will become shallower.

The third branch 2163 is used to adjust the impedance matching degree between the first signal receiving antenna 210 and the first signal receiving antenna 210. The degree of adjustment of the degree of impedance matching with the signal conversion device 120 is smaller than the degree of adjustment of the impedance matching between the first signal receiving antenna 210 and the signal conversion device 120 by the first stub 2161. In other words, the first stub 2161 adjusts the impedance matching between the first signal receiving antenna 210 and the signal conversion device 120 to a greater degree and plays a major role in the impedance matching. The third branch 2163 adjusts the impedance matching between the first signal receiving antenna 210 and the signal conversion device 120 to a small degree, and plays a secondary role in the impedance matching.

The combination of the magnetic dipole makes the directional patterns of the received first network signal combined with each other, ensuring that the first signal receiving antenna 210 has a higher and more stable gain. The combination of the electric dipole and the magnetic dipole and the coupling and feeding manner of the first feeder 216 enables the first signal receiving antenna 210 to have a wider working bandwidth. Therefore, the bandwidth of the first network signal that can be received by the first signal receiving antenna 210 in the present application is 2.5-6 GHz.

The first conductive wire 2191 is the inner core of the feeding wire 219, and the second conductive wire 2192 is the outer core of the feeding wire 219. The first conductive wire 2191 and the second conductive wire 2192 are insulated and isolated by an isolation layer 2193.

The sum of the signal strength of a network signal. The user terminal device 1 further includes a processor 130 which is electrically connected to the first signal receiving antenna 210. The processor 130 selects the N first signal receiving antennas 210 with the largest sum of signal strengths to work according to the quality of the first network signals received by all the first signal receiving antennas 210. Due to the uncertainty of the location of the base station 3, the direction of signal transmission of the first network is also uncertain.

When the bracket 150 is rotatably connected with the base 140, and the second signal receiving antenna 110 is disposed on the bracket 150, when the driver 160 drives the bracket 150 to rotate, the bracket 150 drives the second signal receiving antenna 110 to rotate.

The so-called step angle refers to the mechanical angle that the output shaft of the drive motor 161 has rotated for one pulse of the control signal. The step angle of the driving motor 161 may be, but is not limited to, 3°, 1.5°, 0.75°, 3.6°, or 1.8°. The greater the step angle, the greater the angle at which one pulse of the control signal causes the output shaft of the drive motor 161 to rotate, and the greater the angle that drives the second signal receiving antenna 110 to rotate; on the contrary, The smaller the step angle, the smaller the angle at which one pulse of the control signal causes the output shaft of the driving motor 161 to rotate, and the smaller the angle that drives the second signal receiving antenna 110 to rotate. When the step angle is larger, the angle at which one pulse of the control signal causes the output shaft of the driving motor 161 to rotate, the less pulses required for the output shaft of the driving motor 161 to rotate one revolution; Conversely, when the step angle is smaller, the angle at which one pulse of the control signal causes the output shaft of the drive motor 161 to rotate is smaller, and the pulse required for the output shaft of the drive motor 161 to rotate one revolution is larger. many. For example, for a drive motor 161 with a step angle of 1.8°, the number of pulses required for one revolution is 360/1.8=200. Generally speaking, the step angle of the drive motor 161 is relatively large. If the reducer 162 is not used, if the drive motor 161 is directly used to drive the bracket 150, the angle of each rotation of the bracket 150 is relatively large. , Then, the second signal receiving antenna 110 arranged on the bracket 150 rotates at a larger angle each time, which in turn results in a smaller number of third network signals received by the second signal receiving antenna 110 during one revolution , Which may lead to inaccurate subsequent judgments of the third network signal with the strongest signal based on the signal strength of each collected third network signal. For example, when the step angle of the driving motor 161 is the first angle and the reducer 162 is not used, a pulse of the control signal causes the bracket 150 to rotate from position A to position B, and the signal is the most The direction of the strong third network signal is at the position C between A and B. Then, because the step angle is too large, the driving motor 161 cannot drive the second signal receiving antenna 110 to rotate to point C, and then This makes the judgment of the third network signal with the strongest signal based on the collected signal strength of each third network signal inaccurate.
