The substrate 100 may be a multilayer PCB manufactured by a High Density Interconnect (HDI) process. The first rf chip 201 is located on a side of the substrate 100 departing from the antenna radiator 300, and the second rf chip 202 is located on a side of the substrate 100 departing from the antenna radiator 300. The first rf chip 201 is electrically connected to the first feeding port 210 to feed a first current signal to the first feeding port 210, and the first current signal is fed to the antenna radiator 300 through the first feeding port 210, and the second rf chip 202 is electrically connected to the second feeding port 220 to feed a second current signal to the second feeding port 220, and the second current signal is fed to the antenna radiator 300 through the second feeding port 220. The antenna radiator 300 has at least one feeding point for receiving the first current signal from the first feeding port 210, so that the antenna radiator 300 resonates in the millimeter wave band. And is configured to receive the second current signal from the second feeding port 220, and further, to make the antenna radiator 300 resonate in the sub6GHz band, so that the millimeter wave module 10 can work in the millimeter wave band as a millimeter wave antenna, and can also work in the sub6GHz band as a sub6GHz antenna, thereby solving the problem of coexistence of the millimeter wave antenna and the sub6GHz antenna.
According to the specification of the 3GPP TS 38.101 protocol, 5G mainly uses two sections of frequencies: FR1 frequency band and FR2 frequency band. The frequency range of the FR1 frequency band is 450 MHz-6 GHz, also called sub-6GHz frequency band; the frequency range of the FR2 frequency band is 24.25GHz to 52.6GHz, commonly called millimeter Wave (mm Wave). The 3GPP 15 release specifies the following 5G millimeter wave frequency bands at present: n257(26.5 to 29.5GHz), n258(24.25 to 27.5GHz), n261(27.5 to 28.35GHz) and n260(37 to 40 GHz). The sub6GHz band can cover 450 MHz-6 GHz band, and at the moment, the millimeter wave band can cover 24.25 GHz-52.6 GHz band. 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 operates in the millimeter wave frequency band, the antenna radiator 300 is a directional antenna.
Specifically, since the frequency range of the sub6GHz band is 450MHz to 6GHz and the frequency range of the millimeter wave band is 24.25GHz to 52.6GHz, the wavelength of the radio frequency signal of the sub6GHz band is long, the radio frequency signal can better cross an obstacle, and the antenna radiator 300 is suitable for long-distance transmission, and when the antenna radiator 300 operates in the sub6GHz band, the antenna radiator 300 is an omnidirectional antenna, and can cover a large radiation range. The radio frequency signal wavelength of millimeter wave frequency channel is shorter, is applicable to the great scene of density, works as when antenna radiator 300 works in millimeter wave frequency channel, antenna radiator 300 is directional antenna. At this time, the antenna radiator 300 may radiate directionally, and the advantages of the antenna radiator 300 may be exerted.
In another embodiment, a polarization direction of the antenna radiator 300 when operating in the millimeter wave frequency band is different from a polarization direction of the antenna radiator 300 when operating in the sub6GHz frequency 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 may be excited to resonate at different frequency bands, so that the antenna radiator 300 exhibits dual-band dual-polarization characteristics. That is, the antenna radiator 300 can operate in different frequency bands, and the polarization directions of the antenna radiator 300 are different when the antenna radiator operates in different frequency bands.
In another embodiment, the antenna radiator 300 is configured to synchronously receive and transmit the radio frequency signal in the millimeter wave band and the radio frequency signal in the sub6GHz band under the excitation of the first current signal and the second current signal.
Specifically, because the difference between the radio frequency signals in the millimeter wave band and the sub6GHz band is large, and the problem of coupling between the radio frequency signals in the millimeter wave band and the radio frequency signals in the sub6GHz band is not easy to occur, when the first feed port 210 feeds in the first current signal to make the antenna radiator 300 resonate in the millimeter wave band, the antenna radiator 300 receives and transmits the radio frequency signals in the millimeter wave band; when the second current signal is fed into the second feed port 220 so that the antenna radiator 300 resonates in the sub6GHz band, the antenna radiator 300 receives and transmits a radio frequency signal in the sub6GHz band; the two processes can be carried out simultaneously, the problems of mutual coupling and mutual interference cannot be caused, and the millimeter wave module 10 at the moment can work in a millimeter wave frequency band and a sub6GHz frequency band simultaneously, so that the problem of coexistence of a millimeter wave antenna and a sub6GHz antenna is solved.
The millimeter wave module 10 provided in the embodiment of the application, feed in the first current signal through the first feed port 210 so that the antenna radiator 300 resonates in the millimeter wave frequency band, so as to receive and transmit the radio frequency signal in the millimeter wave frequency band, and feed in the second current signal through the second feed port 220 so that the antenna radiator 300 resonates in the sub6GHz frequency band, so as to receive and transmit the radio frequency signal in the sub6GHz frequency band, so that the millimeter wave module 10 can work in the millimeter wave frequency band as a millimeter wave antenna, and can also work in the sub6GHz frequency band as a sub6GHz antenna, thereby solving the problem of coexistence of the millimeter wave antenna and the sub6GHz antenna.

At this time, the same antenna radiator 300 may work in both the millimeter wave band and the sub6GHz band, thereby solving the problem of coexistence of the millimeter wave antenna and the sub6GHz antenna.
Further, in one embodiment, the first feeding point 310 and the second feeding point 320 are respectively disposed along two adjacent sides of the antenna radiator 300 and are centered with respect to the corresponding sides. The first feeding point 310 may feed a first current signal with a first polarization direction, and the second feeding point 320 may feed a second current signal with 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 implement transceiving of dual-frequency dual-polarized radio frequency signals.

In this embodiment, the first antenna radiator 301 and the second antenna radiator 302 are arranged at an interval, the first feeding point 310 is located at the first antenna radiator 301, the second feeding point 320 is located at the second antenna radiator 302, the first feeding point 310 is configured to receive a first current signal from the first feeding port 210, the first current signal is used to excite the first antenna radiator 301 to resonate in a millimeter wave frequency band to receive and transmit a radio frequency signal in the millimeter wave frequency band, the second feeding point 320 is used to receive a second current signal from the second feeding port 220, and the second current signal is used to excite the second antenna radiator 302 to resonate in a sub6GHz frequency band to receive and transmit 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 transceiving of the millimeter wave signal and the sub6GHz signal can be simultaneously realized, so that the problem of coexistence of the millimeter wave antenna and the sub6GHz antenna is solved.

In one embodiment, the antenna radiator 300 is 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 configured to feed a first current signal from the first feeding port 210 to the antenna radiator 300, the first current signal is configured to excite the antenna radiator 300 to resonate in a millimeter wave frequency band so as to receive and transmit radio frequency signals in a millimeter wave frequency band, the second feeding point 320 is configured to feed a second current signal from the second feeding port 220 to the antenna radiator 300, the second current signal is configured to excite the antenna radiator 300 to resonate in a sub6GHz frequency band so as to receive and transmit radio frequency signals in a sub6GHz frequency band, 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, the short side 300a of the antenna radiator 300 is provided with a first feeding point 310 for receiving and transmitting a radio frequency signal in a millimeter wave frequency band, and the radio frequency signal in the millimeter wave frequency band is a high frequency signal, the long side 300b of the antenna radiator 300 is provided with a second feeding point 320 for receiving and transmitting a radio frequency signal in a sub6GHz frequency band, and the radio frequency signal in the sub6GHz frequency band is a low frequency signal. 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 beneficial to expanding the working frequency band of the antenna radiator 300.
Further, a distance between the first feeding point 310 and the center of the antenna radiator 300 is smaller than a 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. Since 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 at different frequency bands, and further the antenna radiator 300 receives and transmits radio frequency signals of different frequency bands. Specifically, the first rf chip 201 feeds a first current signal to the first feeding port 210, and when the first current signal is received by the first feeding point 310, the antenna radiator may resonate in the millimeter wave band, so as to generate an rf signal in the millimeter wave band. The second rf chip 202 feeds the 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 may resonate in the sub6GHz band, so as to generate the rf signal in the sub6GHz band. 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. That is, the millimeter wave frequency band and the sub6GHz frequency band do not have a frequency band overlapped, and at this time, the antenna radiator 300 operates in the frequency bands independent of each other, and mutual coupling and interference are not generated, so that the function independent of each other can be realized, and the antenna radiator 300 is in a stable and orderly operating state.

Moreover, since the second feeding trace 221 is disposed corresponding to the second micro-slit 500b on the feeding layer 500, the second feeding trace 221 may transmit the received second current signal to the second feeding point 320 on the antenna radiator 300 through the second micro-slit 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 sub-6GHz band. When the first current signal is different from the second current signal, the millimeter wave module 10 may operate in the millimeter wave frequency band as the millimeter wave antenna, or the millimeter wave module 10 may operate in the sub6GHz frequency band as the sub6GHz antenna, thereby facilitating to solve the problem of coexistence of the millimeter wave antenna and the sub6GHz antenna.
Further, the feed layer 500 constitutes a ground of the antenna radiator 300, and the antenna radiator 300 and the feed layer 500 are not directly electrically connected, but ground the antenna radiator 300 by coupling.

With continued reference to fig. 8, the first micro-slit 500a extends in a first direction, and the second micro-slit 500b extends in a second direction, wherein the first direction is perpendicular to the second direction.
The first micro-slit 500a and the second micro-slit 500b are strip-shaped slits. The first micro-slit 500a may be a vertically polarized slit or a horizontally polarized slit, and the second micro-slit 500b may be a vertically polarized slit or a horizontally 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 will be described by taking, as an example, the extending direction of the first micro-slit 500a as the Y direction and the extending direction of the second micro-slit 500b as 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, at this time, the millimeter wave module 10 forms a dual-polarized millimeter wave module, the radiation direction of the millimeter wave module 10 can be adjusted, and the radiation direction can be adjusted to achieve targeted radiation, so that the radiation gain of the millimeter wave module 10 can be improved. The polarization of the antenna refers to the direction of the electric field intensity formed when the antenna radiates. When the electric field intensity direction is vertical to the ground, the electromagnetic wave is called a vertical polarized wave; when the electric field strength is parallel to the ground, the electromagnetic wave is called a horizontally polarized wave. Due to the characteristics of millimeter wave signals, the signals which determine horizontal polarization propagation can generate polarization current signals on the surface of the ground when being close to the ground, the polarization current signals generate heat energy due to the influence of ground impedance, so that electric field signals are attenuated rapidly, and the vertical polarization mode is not easy to generate the polarization current signals, so that the large-amplitude attenuation of energy is avoided, and the effective propagation of the signals is ensured. Therefore, in mobile communication systems, a vertically polarized propagation system is generally used. The dual-polarized antenna generally comprises two modes of vertical polarization, horizontal polarization and +/-45-degree polarization, and the latter mode is superior to the former mode in performance, so that the +/-45-degree polarization mode is adopted for most of the antennas. The dual-polarized antenna combines two pairs of antennas with polarization directions orthogonal to each other at +45 degrees and-45 degrees, and simultaneously works in a receiving-transmitting duplex mode, so that the number of antennas in each cell is greatly saved; meanwhile, the +/-45 degrees are orthogonal polarization, so that 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-polarization antenna).
