In an embodiment, the plurality of antenna arrays includes a first antenna array and at least two second antenna arrays, at least one second antenna array is disposed on each of two sides of the first antenna array, and a radiation direction angle of the first antenna array is opposite to a radiation direction angle of the first antenna array. For example, the plurality of antenna arrays includes a first antenna array and two second antenna arrays, wherein the two second antenna arrays are respectively disposed at two sides of the first antenna array, that is, the first antenna array is disposed between the two second antenna arrays. Wherein a radiation direction angle of the first antenna array is different from a radiation direction angle of the first antenna array.
In one embodiment, the first antenna array is a dual-polarized antenna array and the second antenna array is a single-polarized antenna array. Wherein dual-polarized antenna array 110 comprises a plurality of vertically polarized feed points and a plurality of horizontally polarized feed points. The single-polarized antenna array 110 includes a plurality of vertically polarized feed points. The vertical polarization feed point is used for connecting a vertical polarization feed line, and the horizontal polarization feed point is used for connecting a horizontal polarization feed line.
Furthermore, a plurality of first impedance transformers are arranged on the vertical polarization feeder line, and a plurality of second impedance transformers are arranged on the horizontal polarization feeder line. The first impedance transformer and the second impedance transformer can complete the transformation between different impedances between two sections of transmission lines required to be matched.
In an embodiment, dual-polarized antenna array 110 includes a plurality of dual-polarized patch antennas. The dual-polarized patch antenna is a pie-shaped directional antenna, generates a hemispherical coverage surface, and is transmitted from a mounting point, wherein the transmission range is 30 degrees to 180 degrees, that is, the dual-polarized patch antenna is used for enhancing the coverage of the upper surface of the millimeter wave antenna module, that is, the z-axis direction, referring to fig. 2.
As shown in fig. 3a, dual-polarized antenna array 110 includes a plurality of dual-polarized patch antennas, each of which is a rectangular patch antenna including a vertical polarization feeding point V and a horizontal polarization feeding point H, wherein the vertical polarization feeding point V is located at the center of a first edge of the rectangular patch antenna, the horizontal polarization feeding point H is located at the center of a second edge of the rectangular patch antenna, and the first edge and the second edge are perpendicularly intersected. For example, dual-polarized antenna array 110 may include 4 dual-polarized patch antennas. The 4 dual-polarized patch antennas are arranged linearly, wherein the vertically polarized feed point V and the horizontally polarized feed point H of each dual-polarized patch antenna are understood to be two separate feed points, i.e. the dual-polarized patch antenna comprises two different sets of feed points (V, H).
When the millimeter wave antenna module works and the system transmits vertical/horizontal polarization signals, the transceiver module 130 may transmit the vertical/horizontal polarization signals to the vertical polarization feed line and the horizontal polarization feed line through the SMP radio frequency connectors, and feed the vertical/horizontal polarization signals to the dual-polarized antenna array 110 through the vertical polarization feed point and the horizontal polarization feed point, and the energy coupled to the dual-polarized antenna array 110 excites the resonance of the current, so as to radiate the millimeter wave signals to the space.
In one embodiment, the single-polarized antenna array 110 includes a plurality of single-polarized dipole antennas, and the dipole antennas include a set of vertically polarized feed points. The dipole antenna is typically a round-stick omni-directional antenna, which is covered with horizontal 360-degree signals, and different omni-directional antennas have different vertical transmission angles.

The dipole antenna can also be called as a symmetric dipole antenna, and consists of two arms, and the two arms of the antenna consist of two sections of wires with equal length and equal thickness. The transducers with equal length arms are called dipoles. Each arm is a quarter wavelength long called a half wave dipole. The oscillator having the same overall length as the wavelength is called a full-wave dipole. A dipole antenna (dipole) is a linear conductor with a midpoint disconnected and connected to a feed. That is, the vertically polarized feeding points V may be simultaneously provided at both arm ends of the dipole antenna, and the vertically polarized feeding points V provided at both arm ends may be referred to as a set of feeding points (V). For example, the single-polarized antenna array 110 may also include 4 single-polarized dipole antennas, the 4 single-polarized dipole antennas being in linear rows.
When the millimeter wave antenna module operates and the system transmits a vertical polarization signal, the transceiver module 130 may transmit the vertical polarization signal to the vertical polarization feed line through the SMP rf connector, and feed the vertical/polarization signal to the single-polarized antenna array 110 through the vertical polarization feed point, and the energy coupled to the single-polarized antenna array 110 excites the resonance of the current, so as to radiate the millimeter wave signal to the space.
It should be noted that, when the plurality of antenna arrays 110 receive and transmit millimeter wave signals, various feeding methods may be adopted, for example, microstrip line feeding, coaxial line feeding, coupling feeding, slot feeding, and the like. In this embodiment, the plurality of antenna arrays 110 may be fed in a microstrip line feeding manner to radiate millimeter wave signals in different frequency bands.
A plurality is understood to be a positive integer greater than or equal to 2. For example, the plurality may be 4, 8, 16, etc. positive integers greater than or equal to 2.
As shown in fig. 4, in an embodiment, when the antenna array 110 is a dual-polarized antenna array, a plurality of horizontally polarized feeding points of each dual-polarized antenna array are respectively connected to the transceiver module 130 to form a first millimeter wave transceiver link; a plurality of vertically polarized feed points of each dual-polarized antenna array are respectively connected to the switch module 120 to form a second millimeter wave transceiving link. Meanwhile, when the antenna array 110 is a single-polarized antenna array, the multiple vertical polarization feeding points of each single-polarized antenna array are respectively connected with the open-tube module, and may also form multiple second millimeter wave transceiving links.
In this embodiment, the switching control of the switch module 120 may implement simultaneous vertical polarization and horizontal polarization of the dual-polarized antenna array to implement communication in the millimeter wave frequency band, may also implement simultaneous horizontal polarization of the dual-polarized antenna array and any single-polarized antenna array to implement communication in the millimeter wave frequency band, may implement switching between the multiple antenna arrays 110, and may also increase the coverage area of the millimeter wave signals of the multiple antenna arrays 110, thereby improving the communication quality of the 5G millimeter waves.
In an embodiment, the input terminal of the switch module 120 may be connected to the vertically polarized feeding point of each antenna array 110, and the output terminal of the switch module 120 is connected to the transceiver module 130. That is, the number of inputs of the switch module 120 may be equal to the number of antenna arrays 110.
Specifically, when there is one output end of the switch module 120, the switch module 120 may control the output end to be electrically connected to the antenna array 110 connected to any one of the input ends according to the received switching instruction, so as to electrically connect a second millimeter wave transceiving link formed between any one of the antenna arrays 110 and the transceiving module 130, referring to fig. 4.

In an embodiment, the transceiver module 130 is further configured to up-convert the received predetermined radio frequency signal into a millimeter wave signal when the millimeter wave signal is transmitted, and down-convert the received millimeter wave signal into the predetermined radio frequency signal when the millimeter wave signal is received.
Specifically, when the millimeter wave antenna module operates in a transmitting state, that is, when a millimeter wave signal needs to be transmitted through N dual-polarized patch antennas or single-polarized dipole antennas of one antenna array 110, at this time, the transceiver module 130 may up-convert 1 channel of preset radio frequency signals transmitted by the electronic device to multiple channels of required millimeter wave signals; when the millimeter wave antenna module operates in a receiving state, that is, when the millimeter wave signal needs to be received through N dual-polarized patch antennas or single-polarized dipole antennas of one antenna array 110, at this time, the transceiver module 130 may down-convert the received multipath millimeter wave signal to the required 1-path preset radio frequency signal.
The preset rf signal may be an intermediate frequency signal, and a frequency of the intermediate frequency signal is less than or equal to 10 GHz. The intermediate frequency signal may be obtained by intermediate frequency modulating a baseband signal, for example, the frequency of the intermediate frequency signal obtained by modulating the baseband signal may be 70 MHz.

The frequency conversion unit 131 is configured to receive a preset radio frequency signal, up-convert the preset radio frequency signal to a millimeter wave signal, receive a millimeter wave signal, and down-convert the millimeter wave signal to the preset radio frequency signal.
For example, when transmitting millimeter wave signals, the frequency conversion unit 131 may implement a direct frequency conversion method, that is, the frequency conversion unit 131 may integrate modulation and up-conversion into one. The frequency conversion unit 131 may also implement a two-step conversion method, that is, the frequency conversion unit 131 separates modulation and up-conversion, modulates a lower preset radio frequency signal first, and then up-converts the modulated signal to a higher carrier frequency (millimeter wave signal). Accordingly, when receiving the millimeter wave signal, the frequency conversion unit 131 may also down-convert the millimeter wave signal received by the antenna array 110 to a predetermined radio frequency signal.
The power distribution unit 132 is connected to the frequency conversion unit 131, and is configured to receive and adjust the power distribution ratio of the millimeter wave signal.

Specifically, the phase shift unit 133 includes at least N phase shifters (phasers). The phase shifter can adjust the phase of the millimeter wave. Each phase shifter can receive one path of input millimeter wave signals and carries out phase adjustment on the received millimeter wave signals so as to output millimeter wave signals with a certain phase proportion. That is, the phase shift unit 133 can receive the multiple millimeter wave signals input by the power distribution unit 132, and perform phase adjustment on the multiple millimeter wave signals, respectively, to output multiple millimeter wave signals with a certain phase ratio.
The amplifying unit 134 is connected to the phase shifting unit 133, and receives and amplifies the millimeter wave signal. Specifically, the discharge unit includes N power amplifiers and N low noise amplifiers, wherein the power amplifiers are correspondingly connected to the low noise amplifiers. When the phase-adjusted millimeter wave signal is input to the amplifying unit 134, the millimeter wave signal may be amplified by a power amplifier and a low noise amplifier to output a millimeter wave signal with an amplifying function. Accordingly, the amplifying unit 134 is capable of receiving the multiple millimeter wave signals input by the phase shifting unit 133 and amplifying the multiple millimeter wave signals respectively to output multiple millimeter wave signals with certain amplification functions.
And the filtering unit 135 is connected to the amplifying unit 134, and is configured to receive the millimeter wave signal and perform filtering processing on the millimeter wave signal. Specifically, the filtering unit 135 may include N filters, and the passband of each filter at least includes the operating frequency band of the millimeter wave signal. For example, the filter may be a band pass filter, a high pass filter, a band stop filter, or the like. Each filtering unit 135 may perform filtering processing on the millimeter-wave signal output by the amplifying unit 134 to output a relatively pure millimeter-wave signal to any one of the antenna arrays 110.
