DETAILED DESCRIPTION

[0022] In order to make the purposes, technical solutions and advantages of the present application clearer, the following further describes specific embodiments of the present application with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only parts related to the present application are shown in the accompanying drawings, but not all contents.

[0023] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] Figure 1 A structure diagram of a multi-in-one antenna module provided by an embodiment of the present application is given, referring to Figure 1 The multi-in-one antenna module includes a main combiner 100, a sub-combiner 200, a main antenna module 300 and a sub-antenna module 400.

[0025] The main combiner 100 and the sub-combiner 200 provided by the present scheme are used to simultaneously connect multiple communication modules 500 on the unmanned device. Optionally, different communication modules 500 can correspond to different wireless communication functions, for example, the communication module 500 can be a combination of one or more of a cellular network communication module (such as a 4G, 5G communication module, etc.), an RTK (Real-time kinematic, Real-time kinematic) communication module 500 and a WiFi communication module. The multiple communication modules 500 provided by the present scheme at least include a cellular network communication module and an RTK communication module.

[0026] Each communication module 500 can be simultaneously connected to a main antenna and a sub-antenna (the present scheme connects the main antenna module 300 and the sub-antenna module 400 to the corresponding communication module 500 through the main combiner 100 and the sub-combiner 200). Different types of communication modules 500 can configure different communication channels according to the communication characteristics of the main antenna and the sub-antenna connected thereto. For example, the communication channel connected with the main antenna of the cellular network communication module is a transceiving channel (i.e. a channel that can receive and send data), and the communication channel connected with the sub-antenna is a receiving channel (i.e. a channel that only receives data), the communication channel connected with the main antenna of the RTK communication module and the communication channel connected with the sub-antenna are both receiving channels, and the communication channel connected with the main antenna of the WiFi communication module and the communication channel connected with the sub-antenna are both transceiving channels.

[0027] The main antenna module 300 provided by the scheme includes a plurality of main antenna sub-modules 310 corresponding to a communication module 500 respectively and a first multiplexing module 320. The plurality of main antenna sub-modules 310 are connected to the first multiplexing module 320. The first multiplexing module 320 is connected to the main combiner 100 through a signal transmission line (for example, a radio frequency coaxial line). For example, the main antenna module 300 can be a combination of one or more of a cellular network main antenna 311 sub-module 310, an RTK main antenna sub-module 310, and a WiFi main antenna sub-module 310. The auxiliary antenna module 400 provided by the scheme includes a plurality of auxiliary antenna sub-modules 410 corresponding to a communication module 500 respectively and a second multiplexing module 420. The plurality of auxiliary antenna sub-modules 410 are connected to the second multiplexing module 420. The second multiplexing module 420 is connected to the auxiliary combiner 200 through a signal transmission line (for example, a radio frequency coaxial line). For example, the auxiliary antenna module 400 can be a combination of one or more of a cellular network auxiliary antenna sub-module, an RTK auxiliary antenna sub-module, and a WiFi auxiliary antenna sub-module. The first multiplexing module 320 provided by the scheme can be used to separate the uplink data provided by the main combiner 100 or combine the downlink data provided by each main antenna sub-module 310. The second multiplexing module 420 can be used to separate the uplink data provided by the auxiliary combiner 200 or combine the downlink data provided by each auxiliary antenna sub-module 410.

[0028] The main combiner 100 and the auxiliary combiner 200 provided by the scheme can be used to realize multi-channel frequency combination of different communication modules 500, for example, to realize three-channel frequency combination of a cellular network communication module, an RTK communication module, and a WiFi communication module. For example, the main combiner 100 and the auxiliary combiner 200 can be used to send the downlink data to the corresponding communication module 500 according to the frequency range corresponding to the received downlink data, and send the uplink data sent by each communication module 500 to the main antenna module 300 and the auxiliary antenna module 400. Different communication modules 500 correspond to different frequency ranges. The main combiner 100 and the auxiliary combiner 200 can work according to the set working logic, for example, the main combiner 100 is used as the main data transmission, and when the main combiner 100 is abnormal, it can be switched to the auxiliary combiner 200 for data transmission. The first multiplexing module 320 provided by the scheme can be used to send the uplink data to the corresponding main antenna sub-module 310 according to the frequency range corresponding to the received uplink data, and send the downlink data received by each main antenna sub-module 310 to the main combiner 100. The second multiplexing module 420 provided by the scheme can be used to send the uplink data to the corresponding auxiliary antenna sub-module 410 according to the frequency range corresponding to the received uplink data, and send the downlink data received by each auxiliary antenna sub-module 410 to the auxiliary combiner 200. The frequency range corresponding to the main antenna sub-module 310 and the auxiliary antenna sub-module can be determined based on the frequency range corresponding to the corresponding communication module 500.

[0029] As mentioned above, the first multiplexing module 320 connects the main antenna sub-modules 310 corresponding to different communication modules 500 to the main combiner 100 through one signal transmission line, and the second multiplexing module 420 connects the auxiliary antenna sub-modules 410 corresponding to different communication modules 500 to the auxiliary combiner 200 through one signal transmission line. The main combiner 100 and the auxiliary combiner 200 are simultaneously connected to the plurality of communication modules 500, and the main antenna sub-modules 310 and the auxiliary antenna sub-modules 410 corresponding to different communication modules 500 are respectively connected to the main combiner 100 and the auxiliary antenna sub-modules 410. Each main antenna sub-module 310 and auxiliary antenna sub-module 410 does not need to be individually connected to the communication module 500, which effectively reduces the space occupied by the multi-antenna device and reduces the consumption of wires.

[0030] In one possible embodiment, the main combiner 100 provided by the present scheme includes a third multiplexing module 110, and a plurality of communication modules 500 are respectively connected to the multi-terminal side of the third multiplexing module 110. The single-terminal side of the third multiplexing module 110 is connected to the single-terminal side of the first multiplexing module 320. The third multiplexing module 110 can be used to separate the downlink data provided by the first multiplexing module 320 or combine the uplink data provided by each communication module 500. For example, the third multiplexing module 110 can send the downlink data to the corresponding communication module 500 according to the frequency range corresponding to the received downlink data, and send the uplink data sent by each communication module 500 to the main antenna module 300.

[0031] In one embodiment, the first multiplexing module 320 is configured with a single-end side and a multi-end side, wherein the single-end side is configured with a single connection port, and the multi-end side is configured with a plurality of connection ports, and each main antenna submodule 310 is connected to a communication interface of the multi-end side of the first multiplexing module 320, respectively. Meanwhile, the main combiner 100 is configured with a single-end side and a multi-end side, wherein the single-end side is configured with a single connection port, and the multi-end side is configured with a plurality of connection ports, and each connection port of the main combiner 100 is connected to a communication module 500, respectively. The connection port of the single-end side of the first multiplexing module 320 is connected to the connection port of the single-end side of the main combiner 100, and optionally, the connection port of the single-end side of the first multiplexing module 320 and the connection port of the single-end side of the main combiner 100 can be connected by a radio frequency coaxial line. For example, a radio frequency connector can be arranged on the connection port of the single-end side of the first multiplexing module 320, and a radio frequency connector can be arranged on the connection port of the single-end side of the main combiner 100, and the two radio frequency connectors are connected by a radio frequency coaxial line. According to the scheme, the third multiplexing module 110 is connected to the plurality of communication modules 500 and the first multiplexing module 320, so as to realize the connection and data transmission between each main antenna submodule 310 and the corresponding communication module 500, and each communication module 500 does not need to be connected to the main antenna submodule 310 separately, thereby effectively reducing the consumption of antenna connection cables and the occupation of equipment space by wires while ensuring normal data communication.

[0032] As Figure 2 As shown in a structural schematic diagram of a main combiner provided by the scheme, the third multiplexing module 110 provided by the scheme includes a plurality of first duplexers 111, and each connection port of the multi-end side of the plurality of first duplexers 111 is connected to a communication module 500 or the single-end side of another first duplexer 111, wherein the single-end side of one first duplexer 111 is connected to the single-end side of the first multiplexing module 320. The first duplexer 111 provided by the scheme can be used to separate the downlink data provided by the connected first multiplexing module 320 or another first duplexer 111, or to combine the uplink data provided by the connected communication module 500 and / or another first duplexer 111.

[0033] Exemplarily, the number of the first duplexers 111 can be configured according to the number of the communication modules 500, for example, when the number of the communication modules 500 is n, the number of the corresponding first duplexers 111 can be set to n-1. The plurality of first duplexers 111 can form a tree network structure, one of the first duplexers 111 as a root node of the tree network structure, the single-end side thereof connected to the single-end side of the first multiplexing module 320 through the radio frequency coaxial line, and the rest of the first duplexers 111 as leaf nodes of the tree network structure, the multi-end side of each of the first duplexers 111 can be connected to a communication module 500 or the single-end side of another first duplexer 111. The present scheme realizes the combined connection of the plurality of communication modules 500 through the plurality of first duplexers 111, and connects the plurality of communication modules 500 to the first multiplexing module 320, so that each communication module 500 does not need to be connected to the main antenna submodule 310, which effectively reduces the consumption of the antenna connection cable and the occupation of the device space by the wire while ensuring normal data communication.

[0034] Optionally, when the communication module 500 (for example, the RTK communication module) needs to filter the first frequency range signal (low frequency range signal) and the second frequency range signal (high frequency range signal) in the communication frequency range to improve the anti-interference ability, a first frequency division filtering module can be connected between the communication module 500 and the corresponding first duplexer 111, and the first frequency division filtering module can perform frequency division filtering on the transmission data between the communication module 500 and the corresponding first duplexer 111. Optionally, the first frequency division filtering module can include a ninth duplexer 811, a tenth duplexer 812, a first filter 813 and a second filter 814, wherein the single-end side of the ninth duplexer 811 is connected with the corresponding communication module 500, one connection port of the double-end side of the ninth duplexer 811 is connected with one connection port of the double-end side of the tenth duplexer 812 through the first filter 813, the other connection port of the double-end side of the ninth duplexer 811 is connected with the other connection port of the double-end side of the tenth duplexer 812 through the second filter 814, and the single-end side of the tenth duplexer 812 is connected with one connection port of the multi-end side of the corresponding first duplexer 111. The ninth duplexer 811 can be used to separate the uplink data provided by the connected communication module 500, or combine the downlink data provided by the first filter 813 and the second filter 814, for example, the ninth duplexer 811 distributes the uplink data to the first filter 813 or the second filter 814 according to the frequency range corresponding to the uplink data sent by the communication module 500, the first filter 813 or the second filter 814 filters out the information outside the corresponding frequency range of the uplink data, and sends the filtered uplink data to the tenth duplexer 812, and the duplexer sends the uplink data to the first duplexer 111. The tenth duplexer 812 can be used to separate the downlink data provided by the connected first duplexer 111, or combine the uplink data provided by the first filter 813 and the second filter 814, for example, the tenth duplexer 812 distributes the downlink data to the first filter 813 or the second filter 814 according to the frequency range corresponding to the received downlink data, the first filter 813 or the second filter 814 filters out the information outside the corresponding frequency range of the downlink data, and sends the filtered downlink data to the ninth duplexer 811, and the ninth duplexer 811 sends the downlink data to the communication module 500. Optionally, the ninth duplexer 811 and the tenth duplexer 812 can be GNSS LTCC duplexers, the first filter 813 and the second filter 814 can be surface acoustic wave filters (SAW), and the first frequency division filtering module can be a GNSS high-low frequency duplexer.

[0035] In one possible implementation, the sub-combiner 200 provided by the present solution comprises a fourth multiplexing module 210, and the plurality of communication modules 500 are respectively connected to the multi-terminal side of the fourth multiplexing module 210, and the single-terminal side of the fourth multiplexing module 210 is connected to the single-terminal side of the second multiplexing module 420. The fourth multiplexing module 210 can be configured to send the downlink data to the corresponding communication module 500 according to the frequency range corresponding to the received downlink data, and send the uplink data sent by each communication module 500 to the sub-antenna module 400. The fourth multiplexing module 210 provided by the present solution can be configured to separate the downlink data provided by the second multiplexing module 420, or combine the uplink data provided by each communication module 500.

[0036] In one implementation, the second multiplexing module 420 is configured with a single-terminal side and a multi-terminal side, the single-terminal side is configured with a single connection port, and the multi-terminal side is configured with a plurality of connection ports, and each sub-antenna sub-module 410 is connected to a communication interface of the multi-terminal side of the second multiplexing module 420. At the same time, the sub-combiner 200 is configured with a single-terminal side and a multi-terminal side, the single-terminal side is configured with a single connection port, and the multi-terminal side is configured with a plurality of connection ports, and each connection port of the sub-combiner 200 can be connected to a communication module 500. The connection port of the single-terminal side of the second multiplexing module 420 is connected to the connection port of the single-terminal side of the sub-combiner 200, and optionally, the connection port of the single-terminal side of the second multiplexing module 420 and the connection port of the single-terminal side of the sub-combiner 200 can be connected by a radio frequency coaxial line. For example, a radio frequency connector can be arranged on the connection port of the single-terminal side of the second multiplexing module 420, and a radio frequency connector can be arranged on the connection port of the single-terminal side of the sub-combiner 200, and the two radio frequency connectors are connected by a radio frequency coaxial line. The present solution connects the plurality of communication modules 500 and the second multiplexing module 420 through the fourth multiplexing module 210, realizes the connection and data transmission between each sub-antenna sub-module 410 and the corresponding communication module 500, and each communication module 500 does not need to be connected to the sub-antenna sub-module 410 separately, thereby effectively reducing the consumption of antenna connection cables and the occupation of equipment space by wires while ensuring normal data communication.

[0037] As Figure 3The structure diagram of a sub-combiner provided by the application is shown. The fourth multiplexing module 210 provided by the application includes a plurality of second duplexers 211. The connection ports on the multi-terminal side of the plurality of second duplexers 211 are respectively connected to the single-terminal side of a communication module 500 or other second duplexers 211. The single-terminal side of one of the second duplexers 211 is connected to the single-terminal side of the second multiplexing module 420. The sub-combiner 200 provided by the application is consistent with the main combiner 100. The sub-combiner 200 can be configured by referring to the configuration of the main combiner 100. The second duplexers 211 provided by the application can be used to separate the downlink data provided by the connected second multiplexing module 420 or other second duplexers 211 or to combine the uplink data provided by the connected communication module 500 and / or other second duplexers 211.

[0038] For example, the number of the second duplexers 211 provided by the application can be configured according to the number of the communication modules 500. For example, when the number of the communication modules 500 is n, the number of the corresponding second duplexers 211 can be set to n-1. The plurality of second duplexers 211 can form a tree network structure. One of the second duplexers 211 serves as the root node of the tree network structure. The single-terminal side of the root node is connected to the single-terminal side of the second multiplexing module 420 through a radio frequency coaxial line. The remaining second duplexers 211 serve as leaf nodes of the tree network structure. The multi-terminal side of each of the second duplexers 211 can be connected to the single-terminal side of a communication module 500 or other second duplexers 211. The application realizes the combiner connection of the plurality of communication modules 500 through the plurality of second duplexers 211. The plurality of communication modules 500 are connected to the second multiplexing module 420. Each of the communication modules 500 does not need to be individually connected to the sub-antenna module 410. The consumption of the antenna connection cable is effectively reduced, and the space occupied by the wire is reduced.

[0039] Optionally, when the communication module 500 (for example, the RTK communication module) needs to filter the first frequency range signal (low frequency range signal) and the second frequency range signal (high frequency range signal) in the communication frequency range to improve the anti-interference ability, a second frequency division filtering module can be connected between the communication module 500 and the corresponding second duplexer 211, and the second frequency division filtering module can perform frequency division filtering on the transmission data between the communication module 500 and the corresponding second duplexer 211. Optionally, the second frequency division filtering module can include an eleventh duplexer 815, a twelfth duplexer 816, a third filter 817 and a fourth filter 818, wherein the single-end side of the eleventh duplexer 815 is connected with the corresponding communication module 500, one connection port of the double-end side of the eleventh duplexer 815 is connected with one connection port of the double-end side of the twelfth duplexer 816 through the third filter 817, the other connection port of the double-end side of the eleventh duplexer 815 is connected with the other connection port of the double-end side of the twelfth duplexer 816 through the fourth filter 818, and the single-end side of the twelfth duplexer 816 is connected with one connection port of the multi-end side of the corresponding second duplexer 211. The eleventh duplexer 815 can be used to separate the uplink data provided by the connected communication module 500, or combine the downlink data provided by the third filter 817 and the fourth filter 818, for example, the eleventh duplexer 815 distributes the uplink data to the third filter 817 or the fourth filter 818 according to the frequency range corresponding to the uplink data sent by the communication module 500, the third filter 817 or the fourth filter 818 filters out the information outside the corresponding frequency range of the uplink data, and sends the filtered uplink data to the twelfth duplexer 816, and the duplexer sends the uplink data to the second duplexer 211.

[0041] Optionally, the communication module 500 provided by the scheme comprises a cellular network communication module, an RTK communication module and a WiFi communication module. It is assumed that the frequency range corresponding to the cellular network communication module (taking a 4G communication module as an example) is: low frequency 698MHz-960MHz, high frequency 1710MHz-2170MHz; the frequency range corresponding to the RTK communication module is: low frequency (L2+L5) 1164MHz-1286MHz, high frequency (L1) 1559MHz-1591MHz; the frequency range corresponding to the WiFi communication module is: low frequency 2400MHz-2500MHz, high frequency 5150MHz-5850MHz. The frequency range corresponding to the RTK communication module is determined according to the L1, L2 and L5 frequency bands based on the GPS system, and can also be set according to the frequency bands corresponding to the Beidou, Galileo, Glonass and other satellite systems. It needs to be explained that since the working frequency range of the cellular network communication module and the RTK communication module is relatively close, the difficulty of transmitting and receiving data mainly lies in the distinction of the data corresponding to the cellular network communication module and the RTK communication module, and the working frequency range of the WiFi communication module is higher than that of the cellular network communication module and the RTK communication module, so the WiFi data is relatively easier to distinguish. While merging multiple types of antennas, the scheme accurately distinguishes cellular data, RTK data and WiFi data through the main combiner and the auxiliary combiner, reduces the loss of wires and ensures the accurate and efficient transmission of data.

[0042] The third multiplexing module 110 includes two first duplexers 111. One first duplexer 111 (assuming it is an LTCC duplexer) has its single-ended side connected to the single-ended side of the first multiplexing module 320 via an RF connection cable. One connection port on the double-ended side of the first duplexer 111 is connected to the WiFi communication module, and the other connection port is connected to the single-ended side of the other first duplexer 111 (assuming it is an LC duplexer). One connection port on the double-ended side of the other first duplexer 111 is connected to the cellular network communication module, and the other connection port is connected to the RTK communication module via a first frequency division and filtering module. This solution uses an LC duplexer as the first duplexer 111 to connect to the cellular network communication module, effectively reducing insertion loss in the corresponding frequency band of the cellular network communication module and ensuring the quality of cellular network communication. Correspondingly, the fourth multiplexing module 210 includes two second duplexers 211. One of the second duplexers 211 (assuming it is an LTCC duplexer) has its single-ended side connected to the single-ended side of the second multiplexing module 420 via an RF connection line. One connection port on the double-ended side of the second duplexer 211 is connected to the WiFi communication module, and the other connection port is connected to the single-ended side of the other second duplexer 211 (assuming it is an LC duplexer). One connection port on the double-ended side of the other second duplexer 211 is connected to the cellular network communication module, and the other connection port is connected to the RTK communication module via the second frequency division and filtering module. This solution uses the LC duplexer as the second duplexer 211 to connect to the cellular network communication module, effectively reducing insertion loss in the corresponding frequency band of the cellular network communication module and ensuring the quality of cellular network communication.

[0043] In one possible embodiment, such as Figure 4 As shown in the schematic diagram of a main antenna module, the first multiplexing module 320 provided in this solution includes multiple third duplexers 321. Each connection port on the multi-end side of the multiple third duplexers 321 is connected to a main antenna submodule 310 or the single-end side of another third duplexer 321. The single-end side of one of the third duplexers 321 is connected to a main combiner 100. The third duplexer 321 provided in this solution can be used to separate uplink data provided by the connected main combiner 100 or other third duplexers 321, or to combine downlink data provided by the connected main antenna submodule 310 and / or other third duplexers 321.

[0044] Exemplarily, the number of the third duplexers 321 can be configured according to the number of the main antenna submodules 310, for example, when the number of the main antenna submodules 310 is n, the number of the corresponding third duplexers 321 can be set to n-1. The plurality of third duplexers 321 can form a tree network structure, one of the third duplexers 321 as a root node of the tree network structure, the single-end side of which is connected to the main combiner 100 through the radio frequency coaxial line, and the rest of the third duplexers 321 as leaf nodes of the tree network structure, the multi-end side of each of the third duplexers 321 can be connected to a main antenna submodule 310 or the single-end side of another third duplexer 321. The present scheme realizes the combiner connection of the plurality of main antenna submodules 310 through the plurality of third duplexers 321, and connects the plurality of main antenna submodules 310 to the main combiner 100, so that each main antenna submodule 310 does not need to be connected to the communication module 500, which effectively reduces the consumption of the antenna connection cable and the occupation of the device space by the wire.

The fourth duplexer 421 provided by the present scheme can be used to separate the uplink data provided by the connected secondary combiner 200 or another fourth duplexer 421, or to combine the downlink data provided by the connected secondary antenna submodule 410 and / or another fourth duplexer 421.

[0046] Exemplarily, the number of the fourth duplexers 421 can be configured according to the number of the secondary antenna submodules 410, for example, when the number of the secondary antenna submodules 410 is n, the number of the corresponding fourth duplexers 421 can be set to n-1. The plurality of fourth duplexers 421 can form a tree network structure, one of the fourth duplexers 421 as a root node of the tree network structure, the single-end side of which is connected to the secondary combiner 200 through the radio frequency coaxial line, and the rest of the fourth duplexers 421 as leaf nodes of the tree network structure, the multi-end side of each of the fourth duplexers 421 can be connected to a secondary antenna submodule 410 or the single-end side of another fourth duplexer 421. The present scheme realizes the combiner connection of the plurality of secondary antenna submodules 410 through the plurality of fourth duplexers 421, and connects the plurality of secondary antenna submodules 410 to the secondary combiner 200, so that each secondary antenna submodule 410 does not need to be connected to the communication module 500, which effectively reduces the consumption of the antenna connection cable and the occupation of the device space by the wire.

As shown in Figure 4 the cellular network main antenna 311 submodule 310 provided by the present solution comprises a cellular network main antenna 311 (cellular network on-board antenna), which is connected to one of the connection ports of the multi-end side of one of the third duplexers 321. As shown in Figure 5 the cellular network auxiliary antenna submodule provided by the present solution comprises a cellular network auxiliary antenna 411 (cellular network on-board antenna), a first filter 412, and a first low noise amplifier 413, wherein one end of the first low noise amplifier 413 is connected to one of the connection ports of the multi-end side of one of the fourth duplexers 421, and the other end of the first low noise amplifier 413 is connected to the cellular network auxiliary antenna 411 through the first filter 412. Optionally, the cellular network main antenna 311 provided by the present solution is a passive antenna, and the cellular network auxiliary antenna 411 is an active antenna.

[0048] In one embodiment, the third duplexers 321 connected to the cellular network main antenna 311 and the fourth duplexers 421 connected to the first low noise amplifier 413 are LC duplexers, which effectively reduce the insertion loss of the cellular network main antenna 311 and improve the quality of the cellular network data transmission and reception. The present solution realizes the data transmission and reception of the cellular network communication through the cellular network main antenna 311 submodule 310 and the cellular network auxiliary antenna submodule, and sets the cellular network auxiliary antenna submodule as an active receiving circuit, filters and amplifies the downlink data received by the cellular network auxiliary antenna 411 through the first filter 412 and the first low noise amplifier 413, increases the receiving gain of the cellular network auxiliary antenna submodule, and improves the receiving quality and sensitivity of the cellular network downlink data.

[0049] In one possible embodiment, as shown in Figure 4 and Figure 5As shown, the communication module 500 provided by the scheme includes an RTK communication module, the main antenna submodule 310 and the auxiliary antenna submodule 410 are configured identically, and the main antenna submodule 310 and the auxiliary antenna submodule 410 both include an RTK antenna submodule 610. The RTK antenna submodule 610 includes an RTK antenna 611, a second filter 612, a second low-noise amplifier 613, and a dual-frequency duplex module 614. One end of the dual-frequency duplex module 614 is connected to one connection port of a multi-end side of one of the fourth duplexers 421 (the fourth duplexers 421 connected to the cellular network communication module in the figure). The other end of the dual-frequency duplex module 614 is connected to the RTK antenna 611 through the second low-noise amplifier 613 and the second filter 612. The dual-frequency duplex module 614 provided by the scheme can be used to filter and process the received RTK signals of the first frequency band (for example, the L1 frequency band) and the RTK signals of the second frequency band (for example, the L2+L5 frequency band) respectively, wherein the second frequency band is higher than the first frequency band. The scheme realizes the data transmission and reception of the RTK communication through the RTK antenna submodule 610, and sets the RTK antenna submodule 610 as an active circuit. The downlink data received by the RTK antenna submodule 610 and the uplink data needed to be sent from the RTK antenna submodule 610 are filtered and amplified through the second low-noise amplifier 613 and the second filter 612, so as to increase the gain of the reception and transmission of the RTK communication, and improve the quality and sensitivity of the transmission and reception of the RTK communication data. Optionally, the RTK antenna 611 provided by the scheme is an active antenna.

The fifth duplex filter 6141 and the sixth duplex filter 6142 can be GNSS high-low frequency duplex filters. The single-end side of the fifth duplex filter 6141 is connected to one connection port of the multi-end side of one of the fourth duplex filters 421 (the fourth duplex filter 421 connected to the cellular network communication module in the figure). The two connection ports of the double-end side of the fifth duplex filter 6141 are respectively connected to the first surface acoustic wave filter 6143 and the second surface acoustic wave filter 6144 and the two connection ports of the double-end side of the sixth duplex filter 6142.

For example, the fifth duplex filter 6141 distributes the uplink data to the first surface acoustic wave filter 6143 or the second surface acoustic wave filter 6144 according to the frequency range corresponding to the uplink data sent by the RTK communication module. The first surface acoustic wave filter 6143 or the second surface acoustic wave filter 6144 filters out information outside the corresponding frequency range of the uplink data, and sends the filtered uplink data to the sixth duplex filter 6142. The sixth duplex filter 6142 sends the uplink data to the RTK antenna 611 through the second low-noise amplifier 613 and the second filter 612. The sixth duplex filter 6142 distributes the downlink data to the first surface acoustic wave filter 6143 or the second surface acoustic wave filter 6144 according to the frequency range corresponding to the received downlink data.
