[0024] In the prior art, neither passive antennas nor active antennas have signal conversion capabilities and signal limiting capabilities.

[0025] The embodiment of the present application first provides an antenna. Different from the antenna in the prior art, the antenna provided in the embodiment of the present application includes a signal converter for converting the type and / or frequency band of the signal, and a signal limiter for limiting the signal output of a preset type and / or frequency band. Therefore, the antenna provided in the embodiment of the present application can convert the type and / or frequency band of the signal, and can also limit the signal output of a preset type and / or frequency band, thereby improving the signal processing function of the antenna.

[0026] See also Figure 1 , Figure 1 A schematic structural diagram of an antenna provided in an embodiment of the present application, such as Figure 1 As shown, the antenna 11 may include a signal receiving unit 111 , a signal processing unit 112 , and a signal output unit 113 .

[0027] The signal receiving unit 111 may be connected to the signal processing unit 112 , and the signal processing unit 112 may be connected to the signal output unit 113 .

[0028] The signal receiving unit 111 may be configured to receive a signal and send the received signal to the signal processing unit 112 .

[0029] The type of signal received by the signal receiving unit 111 can be set according to actual needs, and the embodiment of the present application does not specifically limit the type of signal received by the signal receiving unit 111. Exemplarily, the signal receiving unit 111 can be used to receive satellite navigation signals.

[0030] The signal processing unit 112 may be configured to receive the signal sent by the signal receiving unit 111 , and may process the received signal to obtain a processed signal, and then may send the processed signal to the signal output unit 113 .

[0031] Specifically, the signal processing unit 112 may include a signal converter 1121 and a signal limiter 1122. The signal converter 1121 may be used to convert the type and / or frequency band of a signal.

[0032] Exemplarily, the signal converter 1121 may be used to convert a B1I signal in a Beidou signal into an L1C / A signal in a Global Positioning System (GPS) signal.

[0033] Exemplarily, the signal converter 1121 may also be used to convert a Beidou signal in a first frequency band into a Beidou signal in a second frequency band.

[0034] Exemplarily, the signal converter 1121 may also be used to convert a Beidou signal in the third frequency band into a GPS signal in the second frequency band.

[0035] The signal limiter 1122 may be used to limit the output of signals of a preset type and / or frequency band.

[0036] For example, the signal limiter 1122 may be used to limit the output of the B1I signal.

[0037] Exemplarily, the signal limiter 1122 may also be used to limit the output of any signal in the second frequency band.

[0038] Exemplarily, the signal limiter 1122 may also be used to limit the output of the Beidou signal in the second frequency band.

[0039] The signal output unit 113 may be configured to receive the processed signal sent by the signal processing unit 112. After receiving the processed signal, the signal output unit 113 may send the processed signal to a preset signal receiver.

[0040] An application scenario of the antenna 11 provided in an embodiment of the present application is provided below:

[0041] If a certain satellite navigation signal receiver is originally only capable of processing satellite navigation signals of one signal type, if a user wants to change the type of signal that the satellite navigation signal receiver can process, for example, the satellite navigation signal receiver is originally only capable of processing L1C / A signals, and now the user wants the satellite navigation signal receiver to only be able to process B1I signals, at this time, the user can replace the antenna in the satellite navigation signal receiver with the antenna 11 provided in the embodiment of the present application, and set the function of the signal converter 1121 in the antenna 11 to convert the B1I signal into the L1C / A signal. Therefore, the antenna 11 can receive the B1I signal, and can convert the B1I signal into the L1C / A signal through the signal converter 1121 in the antenna 11, and then process the L1C / A signal in the GPS signal. Therefore, the satellite navigation signal receiver after replacing the antenna with the antenna 11 provided in the embodiment of the present application can receive and process the B1I signal.

[0042] Compared with the method of replacing the processor inside the satellite navigation signal receiver, since the antenna of the satellite navigation signal receiver is exposed outside the device, it is more convenient to replace the antenna.

[0043] Another application scenario of the antenna 11 provided in the embodiment of the present application is provided below:

[0044] If a certain satellite navigation signal receiver is capable of receiving signals of multiple types or multiple frequency bands, and now a user wants to limit the types and / or frequency bands of signals that the satellite navigation signal receiver can receive, exemplarily, the satellite navigation signal receiver is originally capable of receiving L1C / A signals, L1C signals, B1I signals and B1C signals, and now the user wants the satellite navigation signal receiver to only receive B1I signals. At this time, the user can replace the antenna in the satellite navigation signal receiver with the antenna 11 provided in the embodiment of the present application, and set the function of the signal limiter 1122 in the antenna 11 to limit the output of the L1C / A signals, L1C signals and B1C signals. Since the antenna 11 can only output B1I signals but cannot output L1C / A signals, L1C signals and B1C signals, the satellite navigation signal receiver after replacing the antenna with the antenna 11 provided in the embodiment of the present application can only receive B1I signals but cannot receive L1C / A signals, L1C signals and B1C signals.

[0045] More specifically, in some scenarios where a certain type and / or frequency band of satellite navigation signals need to be tested separately, the antenna in the prior art does not have a signal limiting function. For example, the antenna in the prior art can only send all of the B1C signal, L1C / A signal, L1C signal, and E1B / C signal to the receiver of the satellite navigation signal, and cannot send any one or more of the B1C signal, L1C / A signal, L1C signal, and E1B / C signal to the receiver of the satellite navigation signal separately. In this case, the antenna 11 provided in the embodiment of the present application can be used to limit the output of any one or more of the B1C signal, L1C / A signal, L1C signal, and E1B / C signal, so that any one or more of the B1C signal, L1C / A signal, L1C signal, and E1B / C signal can be sent separately to the receiver of the satellite navigation signal, thereby meeting the need to test any one or more of the B1C signal, L1C / A signal, L1C signal, and E1B / C signal.

[0046] Therefore, the antenna 11 provided in the embodiment of the present application can be used.

[0047] Compared with the method of replacing the processor inside the satellite navigation signal receiver, since the antenna of the satellite navigation signal receiver is exposed outside the device, it is more convenient to replace the antenna.

[0048] From the above, it can be seen that the embodiment of the present application provides an antenna, which includes a signal receiving unit, a signal processing unit and a signal output unit; the signal receiving unit is connected to the signal processing unit, and the signal processing unit is connected to the signal output unit; the signal processing unit has a signal converter and a signal limiter; wherein the signal converter is used to convert the type and / or frequency band of the signal, and the signal limiter is used to limit the signal output of a preset type and / or frequency band; in this way, the signal can be acquired through the signal receiving unit of the antenna, and then the type and / or frequency band of the signal can be converted through the signal converter in the signal processing unit, and the signal output of the preset type and / or frequency band can be limited through the signal limiter in the signal processing unit, and finally the signal processed by the signal processing unit is output through the signal output unit of the antenna. Therefore, the antenna provided in the present application can convert the type and / or frequency band of the signal, and can also limit the signal output of the preset type and / or frequency band, thereby improving the signal processing function of the antenna.

[0051] Specifically, the signal processing unit 112 in the antenna 11 may further include a signal filter 1123 and a signal amplifier 1124 .

[0052] The signal filter 1123 may be connected to the signal receiving unit 111 , and the signal amplifier 1124 may be connected to the signal filter 1123 and the signal processing unit 112 .

[0054] The signal amplifier 1124 may be configured to receive the signal sent by the signal filter 1123 , perform signal amplification processing on the signal sent by the signal filter 1123 , and send the amplified signal to the signal processing unit 112 .

[0055] The signal processing unit 112 may further include a signal processing circuit board.

[0057] In this implementation, the signal limiter 1122 can be integrated into the signal converter 1121, the signal filter 1123 and the signal amplifier 1124 can also be integrated into the signal converter 1121, and the signal converter 1121 in the signal processing unit 112 can be set on the signal processing circuit board in the signal processing unit 112; alternatively, the signal limiter 1122 can also be independent of the signal converter 1121, and the signal limiter 1122 and the signal converter 1121 can be respectively set on the signal processing circuit boards in the signal processing unit 112.

[0058] In a possible implementation, the signal receiving unit 111 may include an antenna dielectric board.

[0059] The antenna dielectric plate may be manufactured from a passive dielectric material (such as ceramic) according to a specific structure.

[0060] In a possible implementation, the signal output unit 113 may include a coaxial cable, wherein the coaxial cable may have a signal output function and a power transmission function.

[0061] Specifically, the coaxial cable can obtain the signal sent by the signal processing unit 112, and transmit the signal sent by the signal processing unit 112 to the satellite signal receiver body.

[0062] In addition, the coaxial cable can also obtain the power provided by the power supply and transmit the power provided by the power supply to the signal processing unit 112. Specifically, the coaxial cable can transmit the power provided by the power supply to the signal processing circuit board in the signal processing unit 112.

[0063] In a possible implementation, the signal output unit 113 may further include a cable connector.

[0064] The cable connector may be connected to a coaxial cable, and further, the cable connector may be connected to a satellite signal receiver body.

[0065] The coaxial cable can be used to send the signal sent by the signal processing unit 112 to the cable connector. After the cable connector receives the signal sent by the signal processing unit 112, the cable connector can transmit the signal sent by the signal processing unit 112 to the satellite signal receiver body connected to the cable connector.

[0066] In this implementation, the cable connector may be an SMA connector (a typical microwave high-frequency connector).

[0067] In a possible implementation, the antenna 11 provided in the embodiment of the present application may further include a protective casing.

[0068] The protective shell can be arranged outside other devices in the antenna 11. The protective shell can be used to provide waterproof, dustproof and corrosion-proof protection for the antenna 11. In practical applications, the protective shell can be made of corrosion-resistant plastic material.

After that, the signal processing unit can selectively perform signal conversion processing on the signal after the signal filtering and signal amplification processing to convert the signal type and / or frequency band according to user needs, and selectively perform signal limitation processing on the signal after the signal filtering and signal amplification processing to limit the signal output of a preset type and / or frequency band. After the signal processing unit completes processing the signal, it can send the processed signal to the signal output unit.

[0075] The signal output unit may send the received signal to the satellite signal receiver body so that the satellite signal receiver body receives and processes the signal sent by the signal output unit.
