The inventor researches and finds that, with the increasing frequency bands used for mobile communication and the coming of the 5G era, the mobile communication frequency band adds some frequency bands with very wide bandwidth, such as N77 frequency band, the bandwidth is from 3300Mhz to 4200Mhz, and the bandwidth is as high as 900Mhz, which is a very big challenge for antenna design. In the conventional antenna design, as shown in fig. 1, after a transmission path and a reception path of an N77 frequency band exit from a radio frequency modem, they are combined into a radio frequency path by a switch and directly enter one antenna, and the resonance coverage range of a single antenna is only about 500-600M bandwidth, which is difficult to cover 900Mhz bandwidth, even though a single antenna can cover 900Mhz bandwidth, the requirement for the antenna is relatively high, which results in the limitation of the requirement of the internal space and the appearance of the mobile terminal. In addition, because a single antenna has a high requirement on bandwidth, the bandwidth requirement on a filter, a coupling device and the like on a radio frequency path is also high, so that the design of the radio frequency device is more complicated, and the cost is increased.
In order to solve the technical problems, the invention provides an antenna module of a 5G N77 frequency band, a frequency band segmentation method and a mobile terminal, which can change the high bandwidth which is realized by one antenna originally into two antennas, reduce the bandwidth requirement of a single antenna, and reduce the design requirement of the antenna, thereby reducing the requirements and the limitations on the internal space and the appearance of the mobile terminal, and further better meeting the performance requirement of the antenna. Meanwhile, the bandwidth requirement on the radio frequency device can be reduced, the design complexity of the radio frequency device is reduced, and therefore the cost of the device can be reduced.
Referring to fig. 2, the present invention provides a preferred embodiment of an antenna module with a frequency band of 5g n 77.
As shown in fig. 2, the antenna module of a frequency band of 5G n77 provided by the present invention includes: a first antenna 1, a second antenna 2, a radio frequency modem 3, a first switch 4 and a second switch 5. The first antenna 1 and the second antenna 2 can receive signals of different frequency bands; the radio frequency modem 3 is used for receiving and transmitting radio frequency signals; the first switch 4 is connected to the receiving end of the rf modem 3 and the transmitting end of the rf modem 3, respectively, and is configured to combine the transmitting path and the receiving path of the rf signal into a rf path; the second switch 5 is connected to the first switch 4, the first antenna 1, and the second antenna 2, respectively, and is configured to switch a frequency band corresponding to the first antenna 1 and switch a frequency band corresponding to the second antenna 2.
Specifically, for the N77 frequency band, the bandwidth is from 3300Mhz to 4200Mhz, and the bandwidth is as high as 900Mhz, and the resonance coverage range of a single antenna is only about 500-600M bandwidth, and it is difficult to cover the bandwidth to 900Mhz, the present invention divides the N77 frequency band into two sections according to frequency, and realizes support and coverage by two antennas, that is, the coverage is realized by the first antenna 1 and the second antenna 2, for example, the first antenna 1 can support 3300-3700Mhz, the second antenna 2 can support 3700-4200Mhz, wherein the N77 frequency band can be divided into two sections, or divided into two uneven sections according to specific frequency. It should be understood that, in some embodiments, the N77 frequency band may be further divided into three parts, or more than three parts, so as to implement full coverage and support through three antennas or multiple antennas, and in this embodiment, the embodiment of implementing coverage and support through two antennas is described.
The radio frequency modem 3 (Transceiver), also called radio frequency Transceiver, is a radio frequency chip, which has the function of receiving and transmitting radio frequency signals, and is mainly used for modulating and transmitting radio frequency signals, or receiving and demodulating signals. The inside of the radio frequency modem 3 is composed of a transmitter and a receiver, so that a transmission port TX and a reception port RX of the radio frequency modem 3 are separated.
In this embodiment, the first switch 4 is connected to the receiving end of the rf modem 3 and the transmitting end of the rf modem 3, respectively, and the second switch 5 is connected to the first switch 4, the first antenna 1 and the second antenna 2, respectively, in some embodiments, the model of the second switch 5 may be SP2T. After the transmission path and the reception path of N77 come out from the rf modem 3, they are combined into a radio frequency path through the first switch 4, and before entering an antenna (the first antenna 1 or the second antenna 2), the second switch 5 is connected to the first switch 5, wherein the common end of the second switch 5 is connected to the combined radio frequency path, two output ends of the second switch 5 are respectively connected to the first antenna 1 and the second antenna 2, and under the action of the second switch 5, the N77 frequency band can be switched to the corresponding antenna according to the preset setting when the frequency band is different in frequency. The second switch 5 is connected to the baseband chip, and antennas corresponding to the frequency division are preset in a memory inside the baseband chip. The radio frequency modem 3 is also connected with a baseband chip, the baseband chip writes the frequency into an internal memory in advance according to the requirement, and when the mobile terminal is in the N77 frequency band, the baseband chip controls the corresponding pin of the radio frequency modem 3 to work according to the currently required working frequency so as to receive and transmit signals. When the mobile terminal is used, the baseband chip can also instruct the second switch 5 to switch to the first antenna 1 or the second antenna 2 according to the frequency band of the current mobile terminal to perform N77 frequency band transceiving, so as to switch the frequency band corresponding to the first antenna 1, and switch the frequency band corresponding to the second antenna 2.
Therefore, the invention can change the high bandwidth which is realized by one antenna into two antennas, reduces the bandwidth requirement of a single antenna, and reduces the design requirement of the antenna, thereby reducing the requirement and the limitation on the internal space and the appearance of the mobile terminal, and further better meeting the performance requirement of the antenna. Meanwhile, the bandwidth requirement on radio frequency devices can be reduced, for example, the required supported bandwidth of devices such as a filter (SAW) and a coupler used on a radio frequency path is greatly reduced, and the original mode that a single device needs to support 900Mhz is changed into the mode that only partial bandwidth, such as 500Mhz or 600Mhz, needs to be supported. Therefore, the radio frequency device can be manufactured more simply, has lower cost and better performance, namely the design complexity of the radio frequency device is reduced, and the cost of the device can be reduced.
In a further implementation manner of an embodiment, the antenna module for a 5G n77 frequency band further includes: and the radio frequency power amplifier 6 is respectively connected with the transmitting end of the radio frequency modem 3 and the first switch 4, and is used for performing power amplification processing on the radio frequency signal output by the radio frequency modem 3 and outputting the radio frequency signal to the first switch 4.
Specifically, a radio frequency power amplifier (RF PA) is an important component of various wireless transmitters, and in a front-stage circuit of the transmitter, the power of a radio frequency signal generated by a modulation oscillation circuit is very small, and the radio frequency signal needs to pass through a series of amplification-buffer stages, intermediate amplification stages and final power amplification stages, and after sufficient radio frequency power is obtained, the radio frequency signal can be fed to an antenna to be radiated, and in order to obtain sufficient radio frequency output power, the radio frequency power amplifier must be adopted. In this embodiment, the main function of the rf power amplifier is to transmit the signal from the rf modem 3 with enough power, so that the signal can be transmitted over a long distance after being radiated via the first antenna 1 or the second antenna 2.
In a further implementation manner of an embodiment, the antenna module for the 5G n77 frequency band further includes: a first filter 7, said first filter 7 being connected between said radio frequency modem 3 and said first switch 4.
Specifically, the first filter 7 is a surface acoustic wave filter. Generally, a SAW filter is used in the receive diversity path. The signal is received from the first antenna 1 or the second antenna 2, and is filtered by the SAW filter, so as to prevent the signal outside the frequency band from entering the inside of the rf modem 3 to cause blockage, which causes the rf modem 3 to be unable to demodulate the normal useful signal, and the SAW filter functions to allow the signal within a specific frequency range to pass through, and to suppress the signal outside the frequency range.
In a further implementation manner of an embodiment, the antenna module for a 5G n77 frequency band further includes: a first integration switch 8 and a second integration switch 9; the first integrated switch 8 is connected between the first antenna 1 and the second switch 5, and the second integrated switch 9 is connected between the second antenna 2 and the second switch 5.
Specifically, the first integrated switch 8 and the second integrated switch 9 are switches, a common end of the first integrated switch 8 is connected to the first antenna 1, and the other end of the first integrated switch 8 has a plurality of ports respectively connected to radio frequency paths of different frequency bands. When a certain frequency band is used for communication, the first integrated switch 8 is controlled by the radio frequency modem 3 to conduct the radio frequency circuit of the corresponding frequency band with the first antenna 1. Correspondingly, a common end of the second integrated switch 9 is connected to the second antenna 2, and the other end of the second integrated switch 9 has a plurality of ports respectively connected to the radio frequency paths of different frequency bands. When a certain frequency band is used for communication, the second integrated switch 9 is controlled by the radio frequency modem 3 to conduct the radio frequency circuit of the corresponding frequency band with the second antenna 2.
It is understood that, in some embodiments, the N77 frequency band may be combined with other frequency bands by adding a switch or a frequency divider before entering the first antenna 1 or the second antenna 2, so as to share the same antenna (i.e., the first antenna 1 or the second antenna 2).
Referring to fig. 3, another embodiment of an antenna module with a frequency band of 5G n77 is provided in the present invention, which includes: a first antenna 1, a second antenna 2, a radio frequency modem 3, a first switch 4 and a second switch 5.

Specifically, the first transmission path and the first reception path of the N77 frequency band are combined into a radio frequency path through the first switch 4 and enter the first antenna 1, the second transmission path and the second reception path of the N77 frequency band are combined into a second radio frequency path through the switch and enter the second antenna 2, and no additional switch is required before entering the first antenna 1 or before entering the second antenna 2. The N77 frequency band is divided into two parts according to the frequency, namely the N77 transmitting signals are respectively sent out from 2 pins of the radio frequency chip according to the frequency, the receiving signals enter 2 different pins according to the corresponding frequency, namely, the high bandwidth which is originally realized by one antenna can be changed into the realization of two antennas, the bandwidth requirement of a single antenna is reduced, the design requirement of the antenna is reduced, the requirement and the limitation on the internal space and the appearance of the mobile terminal are reduced, and the performance requirement of the antenna can be better met. Meanwhile, the bandwidth requirement on the radio frequency device can be reduced, so that the radio frequency device can be manufactured more simply, is lower in cost and has better performance, the design complexity of the radio frequency device is reduced, and the cost of the device can be reduced.
Further, the antenna module for the 5G n77 frequency band further includes: and the radio frequency power amplifier 6 is respectively connected with the transmitting end of the radio frequency modem 3, the first switch 4 and the second switch 5, and is used for performing power amplification processing on the radio frequency signal output by the radio frequency modem 3 and outputting the radio frequency signal to the first switch 4 or the second switch 5.

In some embodiments, the present invention also provides a mobile terminal, comprising: baseband chip and antenna module of the 5G N77 frequency channel. Wherein the baseband chip is connected with the radio frequency modem and the second switch respectively.
Specifically, the second switch is connected to a baseband chip, and antennas corresponding to frequency division are set in advance in a memory inside the baseband chip. The radio frequency modem is also connected with the baseband chip, the baseband chip writes the frequency into an internal memory in advance according to the requirement, and when the mobile terminal is in the N77 frequency band, the baseband chip controls the corresponding pin of the radio frequency modem to work according to the currently required working frequency so as to receive and transmit signals.

In the technical scheme, the high bandwidth which is realized by one antenna originally can be changed into the high bandwidth which is realized by two antennas, the bandwidth requirement of a single antenna is reduced, and the design requirement of the antenna is reduced, so that the requirements and the limitations on the internal space and the appearance of the mobile terminal are reduced, and the performance requirement of the antenna can be better met. Meanwhile, the bandwidth requirement on radio frequency devices can be reduced, for example, the required supported bandwidth of devices such as a filter (SAW) and a coupler used on a radio frequency path is greatly reduced, and the original mode that a single device needs to support 900Mhz is changed into the mode that only partial bandwidth, such as 500Mhz or 600Mhz, needs to be supported. Therefore, the radio frequency device can be manufactured more simply, has lower cost and better performance, namely the design complexity of the radio frequency device is reduced, and the cost of the device can be reduced.
In summary, according to the antenna module, the frequency band segmentation method, and the mobile terminal for the 5G N77 frequency band provided by the present invention, the transmitting path and the receiving path of the 5G N77 frequency band are combined into one radio frequency path through the first switch and output to the second switch, the second switch is controlled to switch the frequency band corresponding to the first antenna, and the frequency band corresponding to the second antenna, so that the N77 frequency band can be divided into two segments according to the frequency, and the support and the coverage can be realized through the two antennas, so that when the N77 frequency band operates at a non-use frequency, the corresponding antenna can be switched according to a different frequency to perform the transceiving of the N77 frequency band. Therefore, the invention can change the high bandwidth which needs one antenna to realize into two antennas to realize, reduces the bandwidth requirement of single antenna, and reduces the design requirement of the antenna, thereby reducing the requirement and limitation on the internal space of the mobile terminal. Meanwhile, the bandwidth requirement on the radio frequency device can be reduced, so that the radio frequency device can be manufactured more simply, is lower in cost and has better performance, the design complexity of the radio frequency device is reduced, and the cost of the device can be reduced.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
