DETAILED DESCRIPTION

[0023] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0024] In order to support higher rates, LTE-A (Long Term Evolution Advance) technology is usually used to support more bandwidth combinations, thereby realizing resource integration and improving data service rates. Especially when frequency band resources are limited, carrier aggregation (CA) can operate on multiple carriers simultaneously, increase transmission bandwidth, and have a significant qualitative improvement on the improvement of data rates. It can be understood that carrier aggregation can be divided into intra-band carrier aggregation and inter-band carrier aggregation. For intra-band carrier aggregation, the different carrier paths it carries are the same, and for inter-band carrier aggregation, the carrier paths it carries are different.

[0025] In order to solve the problem that different carrier channels need to work simultaneously, a quadplexer is usually used in the related art to separate the frequency bands in pairs. Figure 1 As shown, the antenna device 1 in the related art includes a first selection switch 11, a second selection switch 12, a quadplexer 17, a duplexer 152, a radio frequency transceiver 151, and a first antenna radiator 101, a second antenna radiator 102, and a third antenna radiator 103. The first selection switch 11 can be, for example, a three-pole three-throw switch, which has three first transceiver terminals and three second transceiver terminals, and the three first transceiver terminals are respectively connected to the first antenna radiator 101, the second antenna radiator 102, and the third antenna radiator 103. The second selection switch 12 can be, for example, a TXM switch module, and the second selection switch 12 includes a third transceiver terminal and a fourth transceiver terminal, and the second selection switch 12 is used to select and connect the third transceiver terminal and the fourth transceiver terminal. The three second transceiver terminals of the first selection switch 11 are respectively connected to the third transceiver terminal, the common terminal of the duplexer 152, and the diversity receiving path 16, and the transmitting terminal of the duplexer 152 is connected to the radio frequency receiver. The common end of the quadplexer 17 is connected to the fourth transceiver end of the second selection switch 12 , and the transmit end of the quadplexer 17 is connected to the RF transceiver 151 .

[0026] When implementing the mid-band downlink CA combination B1+B3, the frequency bands B1 and B3 are transmitted to the first selection switch 11 through the first antenna radiator 101, and the first antenna radiator 101 and the third transceiver end are selected to be connected through the first selection switch 11. Then, the third transceiver end and the fourth transceiver end are selected to be connected through the second selection switch 12. Finally, the B1_RX transmitting end and the B3_RX transmitting end of the quadplexer 17 are output to the RF transceiver 151 for demodulation, completing the simultaneous reception of the two downlink carrier signals to implement the downlink CA combination of B1+B3.

[0027] When implementing the mid-high frequency band downlink CA combination B3+B7, the frequency band B3 is transmitted to the first selection switch 11 through the first antenna radiator 101, and the first antenna radiator 101 is selectively connected to the third transceiver end through the first selection switch 11, and then the third transceiver end and the fourth transceiver end are selectively connected through the second selection switch 12, and then the B3_RX transmitting end of the quadplexer 17 is output to the RF transceiver 151 for demodulation, and the downlink B3 carrier reception signal is completed. The frequency band B7 is transmitted to the first selection switch 11 through the second antenna radiator 102, and the second antenna radiator 102 is selectively connected to the third transceiver end through the first selection switch 11, and then the B7_RX transmitting end of the duplexer 152 is output to the RF transceiver 151 for demodulation, and the downlink B7 carrier reception signal is completed. The above completes the downlink CA combination of B3+B7.

[0028] When realizing the receiving path of the single-frequency intermediate frequency band, the frequency band B1 is transmitted to the first selection switch 11 through the first antenna radiator 101, and the first antenna radiator 101 and the third transceiver end are selected to be connected through the first selection switch 11. Then, the third transceiver end and the fourth transceiver end are selected to be connected through the second selection switch 12. Finally, the B1_RX transmitting end of the quadplexer 17 is output to the RF transceiver 151 for demodulation, thereby completing the receiving signal of the downlink B1 carrier.

[0029] Frequency band B3 is transmitted to the first selection switch 11 through the first antenna radiator 101, and the first antenna radiator 101 and the third transceiver end are selected and connected through the first selection switch 11. Then, the third transceiver end and the fourth transceiver end are selected and connected through the second selection switch 12. Finally, it is output from the B3_RX transmitting end of the quadplexer 17 to the RF transceiver 151 for demodulation, thereby completing the reception signal of the downlink B3 carrier.

[0030] However, in the above-mentioned related technologies, when realizing a single-band receiving path, it must pass through the TXM switch module. Since the insertion loss of the TXM switch module is large, the insertion loss of the entire signal link of the antenna device 1 will be large, thereby increasing the difficulty of debugging the antenna device 1.

[0031] In order to solve the above technical problems, in an antenna device provided by the present disclosure, the first selection switch can connect each antenna radiator to the second selection switch or the third selection switch, and the second selection switch and the third selection switch are connected to the RF processing module. In this way, when performing carrier aggregation, antenna signals of different frequency bands can be transmitted to the RF processing module by the second selection switch and the third selection switch respectively through different antenna radiators, and when transmitting antenna signals of a single frequency band, the first selection switch can be used to select a selection switch with smaller insertion loss from the second selection switch and the third selection switch to transmit the antenna signal to the RF processing module, thereby effectively reducing the insertion loss, and further effectively reducing the difficulty of debugging the antenna device and improving the signal strength of the whole device.

[0032] An exemplary embodiment of the present disclosure provides an antenna device, such as Figure 2 As shown, the antenna device 1 includes at least two antenna radiators, a first selection switch 11, a second selection switch 12, a third selection switch 13 and a radio frequency processing module 15. Exemplarily, the antenna device 1 may be provided with only two antenna radiators, or may be provided with more than two antenna radiators, for example Figure 2 The first antenna radiator 101, the second antenna radiator 102 and the third antenna radiator 103 are shown. By providing at least two antenna radiators, signals of different frequency bands can be received.

[0033] The second selection switch 12 includes a first transceiver terminal 121 and a plurality of second transceiver terminals 122, and the second selection switch 12 is used to selectively connect the first transceiver terminal 121 with each second transceiver terminal 122. The third selection switch 13 includes a third transceiver terminal 131 and a plurality of fourth transceiver terminals 132, and the third selection switch 13 is used to selectively connect the third transceiver terminal 131 with each fourth transceiver terminal 132. At least two antenna radiators, the first transceiver terminal 121, and the third transceiver terminal 131 are all connected to the first selection switch 11, and the first selection switch 11 is used to selectively connect each antenna radiator with the first transceiver terminal 121 or the third transceiver terminal 131, so as to realize connecting each antenna radiator with the second selection switch 12 or the third selection switch 13. The plurality of second transceiver terminals 122 and the plurality of fourth transceiver terminals 132 are all connected to the RF processing module 15.

[0034] In this way, when performing carrier aggregation, antenna signals of different frequency bands can be transmitted to the RF processing module 15 through different antenna radiators by the second selection switch 12 and the third selection switch 13 respectively. When transmitting antenna signals of a single frequency band, the first selection switch 11 can select a selection switch with smaller insertion loss from the second selection switch 12 and the third selection switch 13 to transmit the antenna signal to the RF processing module 15, thereby effectively reducing the insertion loss, and further effectively reducing the difficulty of debugging the antenna device 1 and improving the signal strength of the entire machine.

[0035] In one embodiment, the RF processing module 15 includes a RF transceiver 151 and at least one multiplexer connected to the RF transceiver 151, the transmitting end of the multiplexer is connected to the RF transceiver 151, and the common end of the multiplexer is connected to at least one second transceiver end 122 and / or at least one fourth transceiver end 132. Exemplarily, the common end of the multiplexer may be connected only to at least one second transceiver end 122, may be connected only to at least one fourth transceiver end 132, or may be connected to at least one second transceiver end 122 and at least one fourth transceiver end 132 at the same time.

[0036] Such a design can realize two-way transmission of data, thereby realizing the reception and transmission of antenna signals.

[0037] In one embodiment, at least one multiplexer includes multiple duplexers 152, and different duplexers 152 correspond to different antenna frequency bands. For example, one duplexer 152 among the multiple duplexers 152 corresponds to the B1 frequency band, another duplexer 152 corresponds to the B3 frequency band, and another duplexer 152 corresponds to the B7 frequency band, etc. The transmitting end of the duplexer 152 is connected to the RF transceiver 151, and the common end of the duplexer 152 is connected to a second transceiver end 122 and / or a fourth transceiver end 132. Different second transceiver ends 122 are connected to different common ends, and different fourth transceiver ends 132 are connected to different common ends. Compared with a quadplexer, the duplexer 152 has a smaller insertion loss and a lower cost. Therefore, the multiplexer in this embodiment uses the duplexer 152, which can not only further reduce the insertion loss of the signal link, but also effectively reduce the cost.

[0038] In one embodiment, the plurality of duplexers 152 include a first duplexer, the common end of the first duplexer is connected to a second transceiver end 122 and a fourth transceiver end 132 via a fourth selection switch 14, and the fourth selection switch 14 is used to selectively connect the common end of the first duplexer to the second transceiver end 122 or the fourth transceiver end 132. With such a configuration, a combination of different carrier paths can be achieved, thereby effectively improving the uplink and downlink transmission rates and enhancing the user experience.

[0039] Since the cost of a single-pole double-throw switch is relatively low, in one embodiment, the fourth selection switch 14 is a single-pole double-throw switch, which can further reduce the production cost of the antenna device 1.

[0040] In one embodiment, the plurality of duplexers 152 correspond to the B1 frequency band, the B3 frequency band, and the B7 frequency band, respectively. For example, the uplink frequency range of the B1 frequency band is 1920 MHz to 1980 MHz, and the downlink frequency range of the B1 frequency band is 2110 MHz to 2170 MHz. The uplink frequency range of the B3 frequency band is 1710 MHz to 1785 MHz, and the downlink frequency range of the B3 frequency band is 1805 MHz to 1880 MHz. The uplink frequency range of the B7 frequency band is 2500 MHz to 2570 MHz, and the downlink frequency range of the B7 frequency band is 2620 MHz to 2690 MHz. The common end of the duplexer 152 corresponding to the B1 frequency band is connected to a second transceiver end 122 and a fourth transceiver end 132, the common end of the duplexer 152 corresponding to the B3 frequency band is connected to a second transceiver end 122 and a fourth transceiver end 132, and the duplexer 152 corresponding to the B7 frequency band is connected to a fourth transceiver end 132. With such a design, the receiving path of the single-frequency intermediate frequency band and the mid-intermediate frequency band downlink CA combination and the mid-high frequency band downlink CA combination can be realized, and the second transceiver end 122 or the fourth transceiver end 132 is selectively turned on. With such a setting form, the combination of different carrier paths can be realized, thereby effectively improving the uplink and downlink transmission rates.

[0041] For example, Figure 2 As shown, when implementing the mid-band downlink CA combination B1+B3, the frequency band B1 is transmitted to the first selection switch 11 through an antenna radiator, and the antenna radiator and the first transceiver end 121 are selectively connected through the first selection switch 11, and then the first transceiver end 121 and the second transceiver end 122 are selectively connected through the second selection switch 12, and then transmitted to the common end of the duplexer 152 corresponding to the B1 frequency band through the fourth selection switch 14, and finally output from the B1_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, thereby completing the reception signal of the downlink B1 carrier.

[0042] The frequency band B3 is input to the first selection switch 11 through another antenna radiator, and the antenna radiator is selectively connected with the third transceiver terminal 131 through the first selection switch 11, and the third transceiver terminal 131 is selectively connected with a fourth transceiver terminal 132 through the second selection switch 12, and then transmitted to the common end of the duplexer 152 corresponding to the B3 frequency band through another fourth selection switch 14, and finally output from the B3_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, completing the receiving signal of the downlink B3 carrier. The above completes the combination of the downlink CA of B1+B3.

[0043] When implementing the mid-band downlink CA combination B3+B7, the frequency band B3 is input to the first selection switch 11 through an antenna radiator, and the antenna radiator and the first transceiver terminal 121 are selectively connected through the first selection switch 11. Then, the first transceiver terminal 121 and the second transceiver terminal 122 are selectively connected through the second selection switch 12, and then transmitted to the common end of the duplexer 152 corresponding to the B3 frequency band through the fourth selection switch 14, and finally output from the B3_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, thereby completing the reception signal of the downlink B3 carrier.

[0044] The frequency band B7 is input to the first selection switch 11 through another antenna radiator, and the antenna radiator is selectively connected with the third transceiver terminal 131 through the first selection switch 11, and the third transceiver terminal 131 is selectively connected with a fourth transceiver terminal 132 through the second selection switch 12 and transmitted to the common end of the duplexer 152 corresponding to the B7 frequency band, and finally output from the B7_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, completing the receiving signal of the downlink B7 carrier. The above completes the combination of the downlink CA of B3+B7.

[0045] When realizing the receiving path of the single-frequency intermediate frequency band, the frequency band B1 is transmitted to the first selection switch 11 through an antenna radiator, and the antenna radiator and the third transceiver terminal 131 are selectively connected through the first selection switch 11. The third transceiver terminal 131 and a fourth transceiver terminal 132 are selectively connected through the second selection switch 12 and transmitted to the common end of the duplexer 152 corresponding to the B1 frequency band, and finally output from the B1_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, thereby completing the receiving signal of the B1 carrier.

[0046] The frequency band B3 is transmitted to the first selection switch 11 through an antenna radiator, and the antenna radiator and the third transceiver terminal 131 are selectively connected through the first selection switch 11, and the third transceiver terminal 131 and a fourth transceiver terminal 132 are selectively connected through the second selection switch 12, and then transmitted to the common end of the duplexer 152 corresponding to the B3 frequency band through the fourth selection switch 14, and finally output from the B3_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, completing the reception signal of the B3 carrier.

[0047] In one embodiment, at least two antenna radiators include a first antenna radiator 101 and a second antenna radiator 102, wherein the first antenna radiator 101 is used to transmit and receive antenna signals in the B1 frequency band and the B3 frequency band, and the second antenna radiator 102 is used to transmit and receive antenna signals in the B3 frequency band and the B7 frequency band.

[0048] For example, Figure 2As shown, when implementing the mid-band downlink CA combination B1+B3, the frequency band B1 is transmitted to the first selection switch 11 through the first antenna radiator, and the first antenna radiator 101 and the first transceiver end 121 are selectively connected through the first selection switch 11, and then the first transceiver end 121 and the second transceiver end 122 are selectively connected through the second selection switch 12, and then transmitted to the common end of the duplexer 152 corresponding to the B1 frequency band through the fourth selection switch 14, and finally output from the B1_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, thereby completing the reception signal of the downlink B1 carrier.

[0049] The frequency band B3 is input to the first selection switch 11 through the second antenna radiator 102, and the second antenna radiator 102 is selectively connected with the third transceiver terminal 131 through the first selection switch 11, and the third transceiver terminal 131 is selectively connected with a fourth transceiver terminal 132 through the second selection switch 12, and then transmitted to the common end of the duplexer 152 corresponding to the B3 frequency band through another fourth selection switch 14, and finally output from the B3_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, completing the receiving signal of the downlink B3 carrier. The above completes the combination of the downlink CA of B1+B3.

[0050] When implementing the mid-band downlink CA combination B3+B7, the frequency band B3 is input to the first selection switch 11 through the first antenna radiator 101, and the first antenna radiator 101 and the first transceiver end 121 are selectively connected through the first selection switch 11. Then, the first transceiver end 121 and the second transceiver end 122 are selectively connected through the second selection switch 12, and then transmitted to the common end of the duplexer 152 corresponding to the B3 frequency band through the fourth selection switch 14, and finally output from the B3_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, thereby completing the reception signal of the downlink B3 carrier.

[0051] The frequency band B7 is input to the first selection switch 11 through the second antenna radiator 102, and the second antenna radiator 102 and the third transceiver terminal 131 are selectively connected through the first selection switch 11, and the third transceiver terminal 131 and a fourth transceiver terminal 132 are selectively connected through the second selection switch 12 and transmitted to the common end of the duplexer 152 corresponding to the B7 frequency band, and finally output from the B7_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, completing the receiving signal of the downlink B7 carrier. The above completes the combination of the downlink CA of B3+B7.

[0052] When realizing the receiving path of the single-frequency intermediate frequency band, the frequency band B1 is transmitted to the first selection switch 11 through the first antenna radiator 101, and the first antenna radiator 101 and the third transceiver terminal 131 are selected to be connected through the first selection switch 11, and the third transceiver terminal 131 and a fourth transceiver terminal 132 are selected to be connected through the second selection switch 12 and transmitted to the common end of the duplexer 152 corresponding to the B1 frequency band, and finally output from the B1_RX transmitting end of the duplexer 152 to the RF transceiver 151 for demodulation, thereby completing the receiving signal of the B1 carrier.

[0054] In this embodiment, when carrier aggregation is performed, antenna signals of different frequency bands can be transmitted to the RF processing module 15 through different antenna radiators by the second selection switch 12 and the third selection switch 13 respectively. When transmitting antenna signals of a single frequency band, the first selection switch 11 can select a selection switch with smaller insertion loss from the second selection switch 12 and the third selection switch 13 to transmit the antenna signal to the RF processing module 15, thereby effectively reducing the insertion loss, and further effectively reducing the difficulty of debugging the antenna device 1 and improving the signal strength of the entire device.

[0055] In one embodiment, at least two antenna radiators further include a third antenna radiator 103, and the first selection switch 11 is a three-pole three-throw switch, which has three fifth transceiver terminals 111 and three sixth transceiver terminals 112. The three fifth transceiver terminals 111 are respectively connected to the first antenna radiator 101, the second antenna radiator 102, and the third antenna radiator 103, and the three sixth transceiver terminals 112 are respectively connected to the first transceiver terminal 121, the third transceiver terminal 131, and the diversity receiving path 16. With such a setting, different antenna radiators can be connected to different transceiver terminals, so that the optimal signal path can be selected, which improves the efficiency of communication. At the same time, the three-pole three-throw switch is used as the first selection switch 11, which is simple to control and can effectively reduce costs.

[0056] Since the TXM switch module has the advantage of high integration, in one embodiment, the second selection switch 12 is a TXM switch module, which can reduce the complexity and cost of producing the antenna device 1 and improve production efficiency. The third selection switch 13 is a single-pole multi-throw switch, which can further reduce costs.

[0058] The electronic device includes the antenna device 1 as described above. Figure 2 As shown, the antenna device 1 includes at least two antenna radiators, a first selection switch 11 , a second selection switch 12 , a third selection switch 13 and a radio frequency processing module 15 .

[0059] The second selection switch 12 includes a first transceiver terminal 121 and a plurality of second transceiver terminals 122, and the second selection switch 12 is used to selectively connect the first transceiver terminal 121 with each second transceiver terminal 122. The third selection switch 13 includes a third transceiver terminal 131 and a plurality of fourth transceiver terminals 132, and the third selection switch 13 is used to selectively connect the third transceiver terminal 131 with each fourth transceiver terminal 132. At least two antenna radiators, the first transceiver terminal 121, and the third transceiver terminal 131 are all connected to the first selection switch 11, and the first selection switch 11 is used to selectively connect each antenna radiator with the first transceiver terminal 121 or the third transceiver terminal 131, so as to realize connecting each antenna radiator with the second selection switch 12 or the third selection switch 13. The plurality of second transceiver terminals 122 and the plurality of fourth transceiver terminals 132 are all connected to the RF processing module 15.

[0060] In this way, when performing carrier aggregation, antenna signals of different frequency bands can be transmitted to the RF processing module 15 through different antenna radiators by the second selection switch 12 and the third selection switch 13 respectively. When transmitting antenna signals of a single frequency band, the first selection switch 11 can select a selection switch with smaller insertion loss from the second selection switch 12 and the third selection switch 13 to transmit the antenna signal to the RF processing module 15, thereby effectively reducing the insertion loss, and further effectively reducing the difficulty of debugging the antenna device 1 and improving the signal strength of the entire machine.
