According to the 3gpp TS 38.101 protocol provision, 5G mainly uses two segments of frequencies: FR1 band and FR2 band. The frequency range of the FR1 frequency band is 450 MHz-6 GHz, which is also called sub-6GHz frequency band; the frequency range of the FR2 band is 24.25 GHz-52.6 GHz, commonly known as millimeter Wave (mm Wave). The 3GPP 15 release specifies the current 5G millimeter wave band as follows: n257 (26.5-29.5 GHz), n258 (24.25-27.5 GHz), n261 (27.5-28.35 GHz) and n260 (37-40 GHz). The sub6GHz frequency band can cover the frequency band of 450 MHz-6 GHz, and at the moment, the millimeter wave frequency band can cover the frequency band of 24.25 GHz-52.6 GHz. The antenna radiator 300 may be a millimeter wave antenna or a sub6GHz antenna.
In one embodiment, when the antenna radiator 300 operates in the sub6GHz band, the antenna radiator 300 is an omni-directional antenna; when the antenna radiator 300 works in the millimeter wave frequency band, the antenna radiator 300 is a directional antenna.
Specifically, since the frequency range of the sub6GHz band is 450 MHz-6 GHz, and the frequency range of the millimeter wave band is 24.25 GHz-52.6 GHz, the wavelength of the radio frequency signal of the sub6GHz band is longer, the radio frequency signal can better cross an obstacle, and the radio frequency signal is suitable for long-distance transmission, and when the antenna radiator 300 works in the sub6GHz band, the antenna radiator 300 is an omnidirectional antenna, and can cover a larger radiation range. The radio frequency signal wavelength of the millimeter wave frequency band is shorter, and the antenna radiator 300 is a directional antenna when the antenna radiator 300 works in the millimeter wave frequency band. At this time, the antenna radiator 300 can radiate directionally, and the advantage of the antenna radiator 300 can be exerted.
In another embodiment, the polarization direction of the antenna radiator 300 when operating in the millimeter wave band is different from the polarization direction of the antenna radiator 300 when operating in the sub6GHz band.
Specifically, when the feeding points of the antenna radiator 300 are located at different positions and the feeding points at different positions are used for receiving different current signals, the antenna radiator 300 can be excited to resonate in different frequency bands, so that the antenna radiator 300 exhibits dual-band dual-polarization characteristics. That is, the antenna radiator 300 may operate in different frequency bands and polarization directions are different when operating in different frequency bands.
In yet another embodiment, the antenna radiator 300 is configured to receive and transmit the radio frequency signal of the millimeter wave band and the radio frequency signal of the sub6GHz band synchronously under the excitation of the first current signal and the second current signal.
Specifically, because the difference between the millimeter wave frequency band and the sub6GHz frequency band is large, the problem of coupling is not easy to occur between the millimeter wave frequency band and the sub6GHz frequency band, so when the first feeding port 210 feeds in the first current signal, so that the antenna radiator 300 resonates in the millimeter wave frequency band, the antenna radiator 300 receives and transmits the millimeter wave frequency band radio frequency signal; when the second feeding port 220 feeds in the second current signal, so that the antenna radiator 300 resonates in the sub6GHz band, the antenna radiator 300 receives and transmits the radio frequency signal in the sub6GHz band; the two processes can be performed simultaneously, the problems of mutual coupling and mutual interference cannot occur, and the millimeter wave module 10 can work in the millimeter wave frequency band and the sub6GHz frequency band simultaneously, so that the coexistence problem of the millimeter wave antenna and the sub6GHz antenna is solved.
According to the millimeter wave module 10 provided by the embodiment of the application, the first current signal is fed in through the first feed port 210 so that the antenna radiator 300 resonates in the millimeter wave frequency band to receive and dispatch the radio frequency signal in the millimeter wave frequency band, and the second current signal is fed in through the second feed port 220 so that the antenna radiator 300 resonates in the sub6GHz frequency band to receive and dispatch the radio frequency signal in the sub6GHz frequency band, so that the millimeter wave module 10 can work in the millimeter wave frequency band, can work as a millimeter wave antenna, can work in the sub6GHz frequency band and can work as a sub6GHz antenna, and accordingly the coexistence problem of the millimeter wave antenna and the sub6GHz antenna can be solved.

At this time, the same antenna radiator 300 can work in the millimeter wave frequency band as well as the sub6GHz frequency band, so that the coexistence problem of the millimeter wave antenna and the sub6GHz antenna is solved.
Further, in one embodiment, the first feeding point 310 and the second feeding point 320 are disposed along two adjacent sides of the antenna radiator 300, respectively, and centered with respect to the corresponding sides. The first feeding point 310 may feed a first current signal in a first polarization direction, the second feeding point 320 may feed a second current signal in a second polarization direction, the polarization directions of the first current signal and the second current signal are orthogonal to each other, and the first current signal and the second current signal have different frequencies, so that two resonant modes with different frequencies and orthogonal to each other are excited on the antenna radiator 300, so as to realize the receiving and transmitting of dual-frequency dual-polarized radio frequency signals.
With continued reference to fig. 3, the antenna radiator 300 includes a first antenna radiator 301 and a second antenna radiator 302, the first antenna radiator 301 has a first feeding point 310, the first feeding point 310 is electrically connected to the first feeding port 210, the second antenna radiator 302 has a second feeding point 320, and the second feeding point 320 is electrically connected to the second feeding port 220.
In this embodiment, the first antenna radiator 301 and the second antenna radiator 302 are arranged at intervals, the first feeding point 310 is located on the first antenna radiator 301, the second feeding point 320 is located on the second antenna radiator 302, the first feeding point 310 is used for receiving a first current signal from the first feeding port 210, the first current signal is used for exciting the first antenna radiator 301 to resonate in a millimeter wave frequency band so as to transmit and receive a radio frequency signal in the millimeter wave frequency band, the second feeding point 320 is used for receiving a second current signal from the second feeding port 220, and the second current signal is used for exciting the second antenna radiator 302 to resonate in a sub6GHz frequency band so as to transmit and receive a radio frequency signal in the sub6GHz frequency band. At this time, the first antenna radiator 301 works in the millimeter wave frequency band, the second antenna radiator 302 works in the sub6GHz frequency band, and when the first antenna radiator and the second antenna radiator work simultaneously, the receiving and transmitting of millimeter wave signals and sub6GHz signals can be realized simultaneously, so that the problem that the millimeter wave antenna and the sub6GHz antenna coexist is solved.

In a specific embodiment, the antenna radiator 300 has a rectangular patch structure, the antenna radiator 300 has a short side 300a and a long side 300b, the first feeding point 310 is disposed corresponding to the short side 300a of the antenna radiator 300, the second feeding point 320 is disposed corresponding to the long side 300b of the antenna radiator 300, the first feeding point 310 is used for feeding a first current signal from the first feeding port 210 to the antenna radiator 300, the first current signal is used for exciting the antenna radiator 300 to resonate in a millimeter wave frequency band so as to transmit and receive a radio frequency signal in the millimeter wave frequency band, the second feeding point 320 is used for feeding a second current signal from the second feeding port 220 to the antenna radiator 300, the second current signal is used for exciting the antenna radiator 300 to resonate in a sub6GHz frequency band so as to transmit and receive a radio frequency signal in the sub6GHz frequency band, and the minimum frequency of the radio frequency signal in the millimeter wave frequency band is greater than the maximum frequency of the radio frequency signal in the sub6GHz frequency band.
The antenna radiator 300 may be a rectangular patch antenna, and has a short side 300a and a long side 300b, where a first feeding point 310 is disposed on the short side 300a of the antenna radiator 300, and is used for receiving and transmitting radio frequency signals in a millimeter wave frequency band, where the radio frequency signals in the millimeter wave frequency band are high frequency signals, and a second feeding point 320 is disposed on the long side 300b of the antenna radiator 300, and is used for receiving and transmitting radio frequency signals in a sub6GHz frequency band, where the radio frequency signals in the sub6GHz frequency band are low frequency signals. The short side 300a and the long side 300b of the antenna radiator 300 are used to change the electrical length of the antenna radiator 300, so as to change the frequency of the radio frequency signal radiated by the antenna radiator 300, which is helpful to expand the working frequency band of the antenna radiator 300.
Further, the distance between the first feeding point 310 and the center of the antenna radiator 300 is smaller than the distance between the second feeding point 320 and the center of the antenna radiator 300.
Specifically, the first feeding point 310 is disposed near the middle of the short side 300a, and the second feeding point 320 is disposed near the middle of the long side 300 b. Because the relative positions of the first feeding point 310 and the second feeding point 320 are different, the electrical lengths of the antenna radiator 300 are also different, and at this time, the first feeding point 310 and the second feeding point 320 are respectively used for receiving different current signals, so that the antenna radiator 300 resonates in different frequency bands, and further the antenna radiator 300 receives and transmits radio frequency signals in different frequency bands. Specifically, the first rf chip 201 feeds the first current signal toward the first feeding port 210, and when the first current signal is received by the first feeding point 310, the antenna radiator can resonate in the millimeter wave band, so as to generate an rf signal in the millimeter wave band. The second rf chip 202 feeds a second current signal toward the second feeding port 220, and when the second current signal is received by the second feeding point 320, the antenna radiator can resonate in the sub6GHz band, so as to generate an rf signal in the sub6GHz band. The minimum frequency of the radio frequency signal in the millimeter wave frequency band is larger than the maximum frequency of the radio frequency signal in the sub6GHz frequency band. That is, the millimeter wave frequency band and the sub6GHz frequency band do not coincide, at this time, the antenna radiator 300 operates in the mutually independent frequency band, and mutual coupling and interference are not generated, so that the mutually independent function can be realized, and the antenna radiator 300 is in a stable and orderly operating state.

Wherein the metallized vias 110 function to achieve isolation decoupling in the antenna radiator 300. That is, due to the presence of the metallized via holes 110, radiation interference generated between two adjacent antenna radiators 300 due to mutual coupling can be prevented, and the antenna radiators 300 are ensured to be in a stable working state.

Specifically, in order to electrically connect the first rf chip 201 with the antenna radiator 300 and electrically connect the second rf chip 202 with the antenna radiator 300, a first limiting hole 101 and a second limiting hole 102 need to be formed in the substrate 100, and a first rf line 410 is disposed in the first limiting hole 101, where the first rf line 410 is used to electrically connect the antenna radiator 300 and the first feeding port 210, and the first feeding port 210 transmits a first current signal generated by the first rf chip 201 to the antenna radiator 300, so that the antenna radiator 300 resonates in a millimeter wave band, and then the antenna radiator 300 generates a radio frequency signal in the millimeter wave band according to the first current signal. And through setting up second radio frequency line 420 in second spacing hole 102, second radio frequency line 420 is used for carrying out the electrical connection with antenna radiator 300 and second feed port 220, and second feed port 220 transmits the second electric current signal that second radio frequency chip 202 produced to antenna radiator 300 for antenna radiator 300 resonates in sub6GHz frequency channel, then produces the radio frequency signal of sub6GHz frequency channel according to the second electric current signal by antenna radiator 300.

And, since the second feeding trace 221 is disposed corresponding to the second micro-slot 500b on the feeding layer 500, the second feeding trace 221 can transmit the received second current signal to the second feeding point 320 on the antenna radiator 300 through the second micro-slot 500b in a coupling manner, and the antenna radiator 300 is coupled to the second current signal from the second feeding trace 221 to generate a radio frequency signal in the sub6GHz band.

Wherein, the first micro slit 500a and the second micro slit 500b are strip slits. The first micro slit 500a may be a vertical polarized slit or a horizontal polarized slit, and the second micro slit 500b may be a vertical polarized slit or a horizontal polarized slit. When the first micro slit 500a is a vertically polarized slit, the second micro slit 500b is a horizontally polarized slit. When the first micro slit 500a is a horizontally polarized slit, the second micro slit 500b is a vertically polarized slit. The present application describes an example in which the extending direction of the first micro slit 500a is the Y direction and the extending direction of the second micro slit 500b is the X direction. When the extending direction of the first micro-slit 500a is perpendicular to the extending direction of the second micro-slit 500b, the feed layer 500 is a dual-polarized slit coupling feed layer 500, and at this time, the millimeter wave module 10 forms a dual-polarized millimeter wave module, so that the radiation direction of the millimeter wave module 10 can be adjusted, and the radiation direction can be adjusted, so that the radiation gain of the millimeter wave module 10 can be improved. The polarization of an antenna refers to the direction of the electric field strength that is created when the antenna radiates. When the electric field strength direction is perpendicular to the ground, the electromagnetic wave is called a vertical polarized wave; when the electric field strength direction is parallel to the ground, the electromagnetic wave is called a horizontally polarized wave. Due to the characteristics of millimeter wave signals, it is determined that the signals propagated in horizontal polarization can generate polarized current signals on the ground surface when being close to the ground, the polarized current signals are influenced by the ground impedance to generate heat energy so that electric field signals are attenuated rapidly, and the polarized current signals are not easy to generate in a vertical polarization mode, so that great attenuation of energy is avoided, and effective propagation of the signals is ensured. Therefore, in the mobile communication system, a propagation method of vertical polarization is generally adopted. Dual polarized antennas are generally divided into vertical and horizontal polarizations and ±45° polarizations, and the latter is generally superior to the former in performance, so that ±45° polarizations are mostly adopted. The dual-polarized antenna combines antennas with two pairs of polarization directions of +45 degrees and-45 degrees which are mutually orthogonal, and simultaneously works in a receiving and transmitting duplex mode, so that the number of antennas of each cell is greatly saved; meanwhile, as the +/-45 degrees are orthogonal polarization, the good effect of diversity reception is effectively ensured (the polarization diversity gain is about 5dB and is improved by about 2dB compared with a single-pole antenna).
