Description

Technical Field

[0001] This invention relates to the field of mobile communication technology, and in particular to a dual-polarized antenna, network equipment, and network system. Background Technology

[0002] 3GPP has defined five frequency bands (n257 to n261) for millimeter-wave communication, opening up new frequency domain development space for mobile communication. However, higher frequencies lead to more significant wireless signal attenuation. Therefore, to ensure sufficient coverage, base stations need to output greater power. Millimeter-wave chip devices are generally less efficient due to material and manufacturing limitations. Phased arrays, on the other hand, can combine power from multiple amplifiers distributed across the aperture, thus generating very high power. Furthermore, with improved chip integration capabilities, electrically scanned phased arrays, with their advantages of flexible array configuration, short beam switching time, and precise beam pointing, have attracted attention and application in mobile communication.

[0003] In phased array aperture arrays, single-polarization and polarization-separated arrangements are relatively simple. In mobile communication systems, base stations typically support two polarizations simultaneously (e.g., horizontal and vertical polarization, +45° and -45° polarization), and can also support communication with terminal devices using polarization diversity.

[0004] In the traditional PCB design process, the arrangement and definition of dual-polarized antenna arrays and chip arrays, especially at the end branches of parallel feed networks, can lead to intersections. Although a three-dimensional interconnection method using PCBs can achieve interconnection between the antenna array and the chip, it disrupts the strict symmetry rules at the end of the entire feed network, increases the design and manufacturing difficulty of the PCB, and introduces amplitude and phase differences at the end of the feed network, thereby increasing the difficulty of subsequent testing and use. Summary of the Invention

[0005] This application provides a dual-polarized antenna, network device, and network system to address the problem that the existing method of using a three-dimensional interactive printed circuit board to avoid the intersection of the terminal branches of the parallel feed network of the dual-polarized antenna increases the design and manufacturing difficulty of the printed circuit board and introduces amplitude and phase differences at the end of the feed network, thereby increasing the difficulty of subsequent testing and use.

[0013] Optionally, the first antenna element and the second antenna element correspond one-to-one, and the position of the feed point of the second antenna element corresponds to the first target position of the first antenna element corresponding to the second antenna element. The first target position and the position of the feed point of the first antenna element are symmetrical about the vertical axis of symmetry of the first antenna element.

[0014] Wherein, the first antenna element is the antenna element included in the first unit circuit, and the second antenna element is the antenna element included in the second unit circuit.

[0015] Optionally, the phase compensation of the beamforming transceiver front-end chip of the first unit circuit differs from the phase compensation of the beamforming transceiver front-end chip of the second unit circuit by a preset value.

[0016] Optionally, the at least one target circuit includes a first target circuit and a second target circuit, wherein a first wiring harness in the first target circuit is connected to a first wiring harness in the second target circuit, and a second wiring harness in the first target circuit is connected to a second wiring harness in the second target circuit.

[0017] Wherein, the first wire harness is a wire harness that connects the first common terminal of the beamforming transceiver front-end chip in the first unit circuit to the second common terminal of the beamforming transceiver front-end chip in the second unit circuit.

[0021] Optionally, the at least one target circuit further includes a third target circuit and a fourth target circuit;

[0022] The first wire harness of the first target circuit and the first wire harness of the second target circuit are connected by the third wire harness.

[0031] In the dual-polarized antenna of this application embodiment, the common terminals of the beamforming transceiver front-end chips in the first unit circuit and the second unit circuit are arranged facing each other, and the polarization definitions of the common terminals of the beamforming transceiver front-end chips in the two unit circuits are interchanged. That is, the first common terminal of one beamforming transceiver front-end chip is connected to the second common terminal of the other chip, and the second common terminal of one beamforming transceiver front-end chip is connected to the first common terminal of the other chip. This can avoid the phenomenon of crossing when the common terminals of the two beamforming transceiver front-end chips are connected. In order for the dual-polarized antenna to function properly, when the polarization definition of the common terminal of the beamforming transceiver front-end chip in the two unit circuits is swapped, the connection relationship between the antenna element and the port of the beamforming transceiver front-end chip also needs to be swapped within these two unit circuits (that is, in the first unit circuit, the first feed point is connected one-to-one with the first type port of the beamforming transceiver front-end chip, and the second feed point is connected one-to-one with the second type port of the beamforming transceiver front-end chip; in the second unit circuit, the first feed point is connected one-to-one with the second type port of the beamforming transceiver front-end chip, and the second feed point is connected one-to-one with the first type port of the beamforming transceiver front-end chip).

[0032] Therefore, the dual-polarized antenna of this application embodiment can avoid the crossover at the end of the parallel feed network by the method of "polarization definition swapping", and will not increase the design and processing difficulty of the printed circuit board, nor introduce amplitude and phase differences at the end of the feed network, thus not increasing the difficulty of subsequent testing and use.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] This application provides a dual-polarized antenna, network device, and network system to address the problem that the existing method of using a three-dimensional interactive printed circuit board to avoid the intersection of the terminal branches of the parallel feed network of the dual-polarized antenna increases the design and processing difficulty of the printed circuit board and introduces amplitude and phase differences at the end of the feed network, thereby increasing the difficulty of subsequent testing and use.

[0043] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

[0044] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments of this application.

[0045] The network device involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a NodeB in a Wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of this application. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0046] Network devices and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multiple-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0047] In order to understand the dual-polarized antenna provided in the embodiments of this application, the existing dual-polarized antennas are now described as follows:

[0048] Antennas for millimeter-wave base stations are typically manufactured using printed circuit boards. One side contains the antenna unit, while the other side contains the chip and circuitry. The two are connected via vertical interconnection to form a complete communication link.

[0049] The antenna array, composed of multiple antenna elements, is typically arranged in an M×N rectangular array, further divided into several subarrays to accommodate different beam pointing and multi-user scenarios. The aperture of the antenna array is determined based on the parameters of the synthesized beam.

[0050] Specifically, the printed antenna element can adopt a dual-polarization form of a resonator, and the dual-channel dual-polarization beamforming front-end chip (BFIC) can use an 8T8R device, forming a design where each channel corresponds to one polarization and four transmit (TR) channels. For example, Figure 1 The dual-polarized beamforming front-end chip (BFIC) shown can be placed at the geometric center of the four antenna elements 101.

[0051] The common terminal of the beamforming front-end chip is connected to the subsequent circuitry via a feed network for signal processing. The printed circuit board (PCB) can employ a multi-layer stacked structure, where the antenna element and beamforming front-end chip occupy opposite sides of the PCB. In this case, a two-way power divider (such as a T-shaped power divider, a Wilkinson power divider, or a hybrid of both) can be connected in parallel to the feed network to meet the requirements of minimum distance and equidistant spacing between the feed network and each chip. However, this can lead to crossover in the dual-polarized feed, for example… Figure 2 The chips shown have an overlap between IC-1 and IC-3, between IC-2 and IC-4, between IC-5 and IC-7, and between IC-6 and IC-8.

[0052] One solution to the crossover issue in dual-polarization feeds is to utilize the stack-up space of the printed circuit board (PCB). For example, one branch of a two-way power divider can achieve three-dimensional interaction through vias (or blind vias) and traces on the intermediate layer of the PCB. However, this three-dimensional interaction structure between vias (or blind vias) and the intermediate layer can lead to imbalances at both ends of the two-way power divider branch. This results in uneven amplitude and phase distribution from the feed network to each chip, which in turn increases the workload of subsequent array calibration and the complexity and computational burden of amplitude and phase configuration of the array beamforming coefficients.

[0053] Figure 3 A schematic diagram of the structure of a dual-polarized antenna provided in an embodiment of this application is shown.

[0054] like Figure 3 As shown, the dual-polarized antenna provided in this embodiment includes:

[0055] At least one target circuit, each target circuit including a first unit circuit and a second unit circuit, each unit circuit including a beamforming transceiver front-end chip and at least one antenna element, the antenna element including a first feed point and a second feed point, the beamforming transceiver front-end chip including a first common terminal, a second common terminal, a first type port connected to the first common terminal and a second type port connected to the second common terminal;

[0056] The first common terminal and the second common terminal of the beamforming transceiver front-end chip in the first unit circuit are arranged opposite to the first common terminal and the second common terminal of the beamforming transceiver front-end chip in the second unit circuit.

[0057] The first common terminal of the beamforming transceiver front-end chip in the first unit circuit is connected to the second common terminal of the beamforming transceiver front-end chip in the second unit circuit.

[0058] The second common terminal of the beamforming transceiver front-end chip in the first unit circuit is connected to the first common terminal of the beamforming transceiver front-end chip in the second unit circuit.

[0059] The first feed point of the antenna vibrator in the first unit circuit is connected one-to-one with the first type port of the beamforming transceiver front-end chip in the first unit circuit, and the second feed point of the antenna vibrator in the first unit circuit is connected one-to-one with the second type port of the beamforming transceiver front-end chip in the first unit circuit.

[0060] The first feed point of the antenna element in the second unit circuit is connected one-to-one with the second type port of the beamforming transceiver front-end chip in the second unit circuit, and the second feed point of the antenna element in the second unit circuit is connected one-to-one with the first type port of the beamforming transceiver front-end chip in the second unit circuit.

[0061] In this embodiment, the beamforming transceiver front-end chip is a dual-channel chip, for example... Figure 3 The chips IC-1 and IC-2 shown are both beamforming transceiver front-end chips, and both have dual channels (i.e., H channel and V channel).

[0062] For example Figure 3 As shown, the first common terminal V and the second common terminal H of chip IC-1 are arranged opposite to the first common terminal V and the second common terminal H of chip IC-2. Furthermore, the first common terminal V of chip IC-1 is connected to the second common terminal H of chip IC-2, and the second common terminal H of chip IC-1 is connected to the first common terminal V of chip IC-2. That is, in this embodiment of the application, the H channel of chip IC-2 is used as the V channel, and the V channel is used as the H channel.

[0063] In this circuit, the four first-type ports (i.e., 1V to 4V) of chip IC-1 are connected to the first feed points A12 to A42, and the four second-type ports (i.e., 1H to 4H) are connected to the second feed points A11 to A41. Therefore, for the first unit circuit 3011 composed of chip IC-1 and antenna elements A-1 to A-4, the first feed point is connected to the H channel, and the second feed point is connected to the V channel.

[0064] In this embodiment, the H channel of chip IC-2 is used as the V channel, and the V channel is used as the H channel. Therefore, the four first-type ports (i.e., 1V to 4V) of chip IC-2 are connected to the second feed points B11 to B41 respectively, and the four second-type ports (i.e., 1H to 4H) are connected to the first feed points B12 to B42 respectively. That is, for the second unit circuit 3012 composed of chip IC-2 and antenna elements B-1 to B-4, the first feed point is connected to the V channel, and the second feed point is connected to the H channel.

[0065] Therefore, in this embodiment of the application, the connection relationship between the antenna vibrator and the port of the beamforming transceiver front-end chip in the first unit circuit 3011 and the second unit circuit 3012 has been swapped. That is, the polarization of the connection relationship between the feed points of antenna vibrators A-1 to A-4 and the port of chip IC-1, and the connection relationship between the feed points of antenna vibrators B-1 to B4 and the port of chip IC-2 has been swapped.

[0066] As can be seen from the above, in the dual-polarized antenna of this application embodiment, the common terminals of the beamforming transceiver front-end chips in the first unit circuit and the second unit circuit are arranged facing each other, and the polarization definitions of the common terminals of the beamforming transceiver front-end chips in the two unit circuits are interchanged. That is, the first common terminal of one beamforming transceiver front-end chip is connected to the second common terminal of the other chip, and the second common terminal of one beamforming transceiver front-end chip is connected to the first common terminal of the other chip. This can avoid the phenomenon of crossing when the common terminals of the two beamforming transceiver front-end chips are connected. In order for the dual-polarized antenna to function properly, when the polarization definition of the common terminal of the beamforming transceiver front-end chip in the two unit circuits is swapped, the connection relationship between the antenna element and the port of the beamforming transceiver front-end chip also needs to be swapped within these two unit circuits (that is, in the first unit circuit, the first feed point is connected one-to-one with the first type port of the beamforming transceiver front-end chip, and the second feed point is connected one-to-one with the second type port of the beamforming transceiver front-end chip; in the second unit circuit, the first feed point is connected one-to-one with the second type port of the beamforming transceiver front-end chip, and the second feed point is connected one-to-one with the first type port of the beamforming transceiver front-end chip).

[0067] Therefore, the dual-polarized antenna of this application embodiment can avoid the crossover at the end of the parallel feed network by the method of "polarization definition swapping", and will not increase the design and processing difficulty of the printed circuit board, nor introduce amplitude and phase differences at the end of the feed network, thus not increasing the difficulty of subsequent testing and use.

[0068] Optionally, the first antenna element and the second antenna element correspond one-to-one, and the position of the feed point of the second antenna element corresponds to the first target position of the first antenna element corresponding to the second antenna element. The first target position and the position of the feed point of the first antenna element are symmetrical about the vertical axis of symmetry of the first antenna element.

[0069] Wherein, the first antenna element is the antenna element included in the first unit circuit, and the second antenna element is the antenna element included in the second unit circuit.

[0070] For example Figure 4 The correspondence between the antenna elements in the first unit circuit 3011 and the antenna elements in the second unit circuit 3012 is as follows: antenna element A-1 corresponds to antenna element B-1, antenna element A-2 corresponds to antenna element B-2, antenna element A-3 corresponds to antenna element B-3, and antenna element A-4 corresponds to antenna element B-4.

[0071] In this embodiment, the position of the feed point of the first antenna element corresponds to the first target position of the first antenna element corresponding to the second antenna element. The first target position and the position of the feed point of the first antenna element are symmetrical about the vertical axis of symmetry of the first antenna element. For example, the position of the feed point of antenna element A-1 after being symmetrical about its own vertical axis of symmetry corresponds to the position of the feed point of antenna element B-1.

[0072] Therefore, the feed point of the first antenna element is symmetrical about itself. After obtaining the first target position, the antenna element with the feed point set at the first target position is the second antenna element.

[0073] In this embodiment, the first common terminal and the second common terminal of the first unit circuit are arranged opposite to the first common terminal and the second common terminal of the second unit circuit. Therefore, in Figure 4 In the middle, the first feed point A12 and the second feed point A11 of antenna element A-1 are symmetrical about their own vertical direction, and then rotated 180 degrees to become the first feed point B12 and the second feed point B11 of antenna element B-1.

[0074] Furthermore, since the connection relationships between the antenna vibrator and the ports of the beamforming transceiver front-end chip in the first and second unit circuits are swapped in this embodiment, therefore, for Figure 4 In the second unit circuit 3012 shown, the first feed point is connected to the V channel, and the second feed point is connected to the H channel. Therefore, if the feed point of the antenna element in the second unit circuit 3012 is located at the same position as the feed point of the antenna element in the first unit circuit 3011, the following will occur: Figure 3 The wiring harnesses shown cross (for example, the connection line between the first feed point B32 and chip IC-2 crosses with the connection line between the second feed point B31 and chip IC-2). This increases the design and manufacturing difficulty of the printed circuit board, making it difficult to achieve such connections, and thus making beamforming difficult.

[0075] Therefore, in this embodiment of the application, by setting "the position of the feed point of the first antenna element corresponds to the first target position of the first antenna element corresponding to the second antenna element, and the first target position and the position of the feed point of the first antenna element are symmetrical about the vertical axis of symmetry of the first antenna element", it is possible to achieve the following: Figure 4 As shown, to avoid the following Figure 3 The diagram shows a wire harness crossing phenomenon.

[0076] Optionally, the phase compensation of the beamforming transceiver front-end chip of the first unit circuit differs from the phase compensation of the beamforming transceiver front-end chip of the second unit circuit by a preset value.

[0077] Among them, the first preset value is related to the position of the feed point of the first antenna vibrator and the position difference of the feed point of the second antenna vibrator, as well as the length of the wire harness connecting the first antenna vibrator and the beamforming transceiver front-end chip, and the length of the wire harness connecting the second antenna vibrator and the beamforming transceiver front-end chip.

[0078] When the length of the wiring harness connecting the first antenna element to the beamforming transceiver front-end chip is equal to the length of the wiring harness connecting the second antenna element to the beamforming transceiver front-end chip, the first preset value is related to the difference between the position of the feed point of the first antenna element and the position of the feed point of the second antenna element.

[0079] For example Figure 4 In antenna element A-1, the current flows from left to right starting from the second feed point A11, and from bottom to top starting from the first feed point A12; in antenna element B-1, the current flows from left to right starting from the second feed point B11, and from top to bottom starting from the first feed point B12. Therefore, the current phase on antenna element A-1 and the current phase on antenna element B-1 are 180 degrees out of phase in the vertical direction. Therefore, if... Figure 4 If the length of the wire harness connecting antenna elements A-1 to A-4 to chip IC-1 is equal to the length of the wire harness connecting antenna elements B-1 to B-4 to chip IC-2, then the first preset value is 180 degrees.

[0080] Optional, such as Figure 5 As shown, the at least one target circuit includes a first target circuit 301 and a second target circuit 302. The first wiring harness 501 in the first target circuit is connected to the first wiring harness 501 in the second target circuit, and the second wiring harness 502 in the first target circuit is connected to the second wiring harness 502 in the second target circuit.

[0081] Wherein, the first wire harness 501 is a wire harness that connects the first common terminal of the beamforming transceiver front-end chip in the first unit circuit and the second common terminal of the beamforming transceiver front-end chip in the second unit circuit.

[0082] The second wiring harness 502 is a wiring harness that connects the second common terminal of the beamforming transceiver front-end chip in the first unit circuit to the first common terminal of the beamforming transceiver front-end chip in the second unit circuit.

[0083] It should be noted here that the connection relationship between the beamforming transceiver front-end chip and the antenna vibrator in the first target circuit, and the connection relationship between the beamforming transceiver front-end chip and the antenna vibrator in the second target circuit, as described above, will not be repeated here.

[0084] For example Figure 5As shown, in the first target circuit 301, the first common terminal V and the second common terminal H of chip IC-1 are positioned opposite to the first common terminal V and the second common terminal H of chip IC-2. Furthermore, the first common terminal V of chip IC-1 is connected to the second common terminal H of chip IC-2, and the second common terminal H of chip IC-1 is connected to the first common terminal V of chip IC-2. That is, in this embodiment, the H channel of chip IC-2 is used as the V channel, and the V channel is used as the H channel. Therefore, the connection relationship between the port of chip IC-1 and the feed point of the antenna vibrator needs to be reversed with the connection relationship between the port of chip IC-2 and the feed point of the antenna vibrator.

[0085] In the second target circuit 302, the first common terminal V and the second common terminal H of chip IC-3 are positioned opposite to the first common terminal V and the second common terminal H of chip IC-4. Furthermore, the first common terminal V of chip IC-3 is connected to the second common terminal H of chip IC-4, and the second common terminal H of chip IC-3 is connected to the first common terminal V of chip IC-4. That is, in this embodiment, the H channel of chip IC-4 is used as the V channel, and the V channel is used as the H channel. Therefore, the connection relationship between the port of chip IC-3 and the feed point of the antenna vibrator needs to be reversed compared to the connection relationship between the port of chip IC-4 and the feed point of the antenna vibrator.

[0086] Among them, if Figure 5 In this design, the antenna element connected to chip IC-3 is called the third antenna element, and the antenna element connected to chip IC-4 is called the fourth antenna element. The third antenna element and the fourth antenna element are in one-to-one correspondence, and the position of the feed point of the fourth antenna element corresponds to the second target position of the third antenna element corresponding to the fourth antenna element. The second target position and the position of the feed point of the third antenna element are symmetrical about the vertical axis of symmetry of the third antenna element.

[0087] Therefore, in this embodiment of the application, by setting "the position of the feed point of the fourth antenna element corresponds to the second target position of the third antenna element corresponding to the fourth antenna element, and the second target position and the position of the feed point of the third antenna element are symmetrical about the vertical axis of symmetry of the third antenna element", the situation of the connection harness between the antenna element and the beamforming transceiver front-end chip is avoided.

[0088] In addition, in the second target circuit, the phase compensation of chip IC-3 differs from the phase compensation of chip IC-4 by a second preset value.

[0089] Among them, the second preset value is related to the position difference between the feed point of the third antenna vibrator and the feed point of the fourth antenna vibrator, as well as the length of the wiring harness connecting the third antenna vibrator and the IC-3 chip, and the length of the wiring harness connecting the fourth antenna vibrator and the IC-4 chip.

[0090] When the length of the wiring harness connecting the third antenna element to chip IC-3 is equal to the length of the wiring harness connecting the fourth antenna element to chip IC-4, the second preset value is related to the difference between the positions of the feed points of the third antenna element and the fourth antenna element.

[0091] Optional, such as Figure 5 As shown, the midpoint of the first wire harness 501 in the first target circuit 301 is connected to the midpoint of the first wire harness 501 in the second target circuit 302; the midpoint of the second wire harness 502 in the first target circuit 301 is connected to the midpoint of the second wire harness 502 in the second target circuit 302, which enables the branches of each stage of the power divider network to be of equal length and equal phase.

[0092] The wire harness connecting the midpoint of the first wire harness 501 in the first target circuit 301 and the midpoint of the first wire harness 501 in the second target circuit 302 can be called the "third wire harness 503"; the wire harness connecting the midpoint of the second wire harness 502 in the first target circuit 301 and the midpoint of the second wire harness 502 in the second target circuit 302 can be called the "fourth wire harness 504".

[0093] In addition, Figure 5 When the lengths of the first wire harness 501 and the second wire harness 502 in the first target circuit 301 and the second wire harness 502 in the second target circuit 302 are equal, the third wire harness 503 will overlap with the fourth wire harness 504. However, this problem can be solved by using a multilayer stacked structure on the printed circuit board. Figure 5 To clearly show that the third harness 503 and the fourth harness 504 are not shown overlapping.

[0094] Optional, such as Figure 5 As shown, the at least one target circuit further includes a third target circuit 303 and a fourth target circuit 304;

[0095] The first wire harness of the first target circuit and the first wire harness of the second target circuit are connected by the third wire harness.

[0096] The second wiring harness of the first target circuit and the second wiring harness of the second target circuit are connected by the fourth wiring harness.

[0097] The first wire harness of the third target circuit and the first wire harness of the fourth target circuit are connected by the fifth wire harness;

[0098] The second wiring harness of the third target circuit and the second wiring harness of the fourth target circuit are connected by the sixth wiring harness;

[0099] The third wire harness is connected to the fifth wire harness, and the fourth wire harness is connected to the sixth wire harness.

[0100] It should be noted here that the connection relationship between the beamforming transceiver front-end chip and the antenna vibrator in the third target circuit, and the connection relationship between the beamforming transceiver front-end chip and the antenna vibrator in the fourth target circuit, as mentioned above, will not be repeated here.

[0101] Optional, such as Figure 5 As shown, the midpoint of the third wire harness 503 is connected to the midpoint of the fifth wire harness 505, and the midpoint of the fourth wire harness 504 is connected to the midpoint of the sixth wire harness 506, which enables the branches of each stage of the power divider network to have equal length and equal phase.

[0102] Optionally, in the same unit circuit, the length of the wire harness connecting each of the first feed points and the beamforming transceiver front-end chip is equal, and the length of the wire harness connecting each of the second feed points and the beamforming transceiver front-end chip is equal.

[0103] In this embodiment, the distance from the antenna feed point to the port of the beamforming transceiver front-end chip is equidistant, which facilitates the configuration calculation of the phase shifter inside the chip in the later array.

[0104] In summary, the specific implementation of the dual-polarized antenna in this application can be as follows: Figure 5 As shown, relative to chips IC-1, IC-3, IC-5, and IC-7, the polarization definitions of chips IC-2, IC-4, IC-6, and IC-8 are swapped, and the polarization of the ports connected to the feed points of the antenna elements connected to chips IC-2, IC-4, IC-6, and IC-8 is swapped, making the parallel feed network completely symmetrical and the transmission path optimal, thereby ensuring consistent electrical performance between the ports of each network branch.

[0105] Specifically, based on the aforementioned "polarization swap," if the feed point positions of the antenna elements connected to chips IC-2, IC-4, IC-6, and IC-8 are set according to the feed point positions of the antenna elements corresponding to chips IC-1, IC-3, IC-5, and IC-7, the following will occur: Figure 3 The crossover pattern shown increases the design and fabrication difficulty of the printed circuit board, making it difficult for the antenna elements corresponding to chips IC-1 to IC-8 to perform beamforming in the same polarization direction. Therefore, it is possible to Figure 5 The positions of the feed points of the antenna elements corresponding to IC-1, IC-3, IC-5, and IC-7 are mirrored along the Y-axis (i.e., the vertical direction). The resulting new antenna element serves as... Figure 5 The antenna vibrator is connected to the chips IC-2, IC-4, IC-6, and IC-8.

[0106] Furthermore, due to the aforementioned "Y-axis mirroring," a certain phase difference arises between the antenna elements before and after the mirroring (e.g., the antenna element connected to IC-1 and the antenna element connected to IC-2). This phase difference can be uniformly compensated within the phase shifting mechanism of the beamforming front-end chip, ensuring that the phase of the antenna elements in the array aperture is controllable during beamforming. Specifically, this can be achieved by... Figure 5 The chips IC-1, IC-3, IC-7, and IC-5 are grouped together and managed under a unified "control data stream-1" for phase compensation. Chips IC-2, IC-4, IC-8, and IC-6 are grouped together and managed under a unified "control data stream-2" for phase compensation. This arrangement facilitates the identification of control data for the beamforming front-end chips.

[0107] It should be noted here that it can be done according to Figure 5 The arrangement rules shown can be extrapolated, meaning that the antenna array and chip array under the corresponding aperture of the phased array can be expanded accordingly according to system requirements to achieve an array size of M×N that meets system requirements.

[0108] As can be seen from the above, the embodiments of this application achieve the optimal solution of the antenna array and chip arrangement and the feed network with the shortest, equidistant, and equal phase by redefining the two polarizations of the beamforming front-end chip under the phased array aperture, rearranging the antenna synchronization, and making full use of the priority of the importance of signals in the printed circuit board stack. At the same time, it simplifies the information planning in the phase control link during array scanning.
