The antenna switching apparatus 100 in the embodiment of the present application is a targeted solution provided to solve a series of problems, such as large occupied space, hardware resource waste, inconvenience in integrating new communication functions, poor antenna performance and/or poor use effectiveness, caused by that each communication function configures a coil independently and a coil antenna implementing different communication functions is in an on state by default in an on state in the existing antenna design scheme.
As shown in fig. 1, the antenna switching apparatus 100 includes a switch 11, a signal detection module 12, a plurality of communication modules 13, and a plurality of first antennas 14, for example, the number of the communication modules 13 is M, the number of the first antennas 14 is N, the number of the first antennas 14 and the number of the communication modules 13 may be specifically set according to actual requirements, M and N may be the same value or different values, that is, one first antenna 14 may correspond to one communication module 13, or one first antenna 14 corresponds to a plurality of communication modules 13, or a plurality of first antennas 14 corresponds to one communication module 13. That is, one first antenna 14 may be coupled to one or more communication modules 13 to form a radio frequency path, and one communication module 13 may also be coupled to one or more first antennas 14 to form a radio frequency path.
As shown in fig. 1, the M communication modules 13 are connected to the N first antennas 14 through the switch 11, specifically, the switch 11 may include M second terminals and N third terminals, each second terminal is connected to one communication module 13, and each third terminal is connected to one first antenna 14, that is, the switch may be a multi-pole multi-throw switch. In the embodiment of the present application, a suitable radio frequency path may be switched and communicated between the M communication modules 13 and the N first antennas 14 through the switch 11 to support the current communication function requirement, that is, the gating of each first antenna 14 and the corresponding communication module 13 may be realized. For any first antenna 14 in the N first antennas 14, at least one communication module 13 in the M communication modules 13 is matched with the first antenna 14, and similarly, for any communication module 13 in the M communication modules 13, at least one first antenna 14 in the N first antennas 14 is matched with the communication module 13.
The communication module 13 is mainly responsible for generating communication signals and modulating and demodulating signal data, and different communication modules 13 can be respectively used for realizing different communication functions.
The first antennas 14 may be coils, and may form antenna loops as shown in fig. 1, where each first antenna 14, that is, each antenna loop, is configured to cooperate with each communication module to implement a corresponding communication function, where different first antennas 14 may be respectively configured to receive communication signals corresponding to different communication functions, that is, each first antenna 14 may be respectively configured to implement one communication function, so that the N first antennas 14 may be at least configured to implement N communication functions, and a combination of a plurality of first antennas in the N first antennas 14 may also form other communication functions. For example, one first antenna 14 is used to implement a remote control function (such as a car key), another first antenna 14 is used to implement an NFC access control function, and another first antenna 14 is used to implement a wireless charging function.
The switch 11 further includes a first end, which may be a signal control end, the first end of the switch 11 may be electrically connected to the signal detection module 12, the signal detection module 12 is configured to receive and detect an external communication signal, so as to determine which type of communication signal is currently the communication signal, which communication function needs to be enabled, and further output a corresponding switch signal to the switch 11, so that the switch 11 may correspondingly switch and gate the target first antenna and the target communication module according to a detection result of the signal detection module 12, so as to successfully enable an antenna path matched with the currently required communication function. In addition, in the embodiment of the present application, the switch 11 may switch and gate only the target first antenna and the target communication module that are matched with the current scenario, and keep the other first antennas in a non-conducting state, that is, in an off state, that is, the first antenna, except the target first antenna, of the N first antennas 14 is not connected to any communication module of the M communication modules.
In one embodiment, the antenna switching apparatus 100 may further include a main control module, the signal detection module 12 may be connected to the first end of the switch 11 through the main control module, that is, the signal detection module 12 is connected to one end of the main control module, and is connected to the other end of the main control module and the first end of the switch 11, the signal detection module 12 detects a certain parameter of the current external communication signal and transmits a detection result to the main control module, the main control module determines a communication function corresponding to the current external communication signal, determines a target first antenna and a target communication module that need to be gated, and then sends a corresponding control signal to the switch 11, and the switch 11 gates the target first antenna and the target communication module accordingly.
The signal detection module 12 may include a second antenna 121 and a signal detection unit 122, wherein one end of the signal detection unit 122 is connected to the second antenna 121, and the other end of the signal detection unit 122 is connected to the first end of the switch 11; the second antenna 121 is configured to receive an external communication signal, and the signal detection unit 122 is configured to detect a parameter of the external communication signal.
Specifically, the second antenna 121 may be a coil for receiving an external communication signal, the second antenna 121 transmits the received external communication signal to the signal detection unit 122 for detection, and the signal detection unit 122 detects a certain parameter of the external communication signal, such as frequency, power, strength, waveform, and the like, so as to determine the type of the external communication signal according to the detection result, and determine a specific corresponding communication function, specifically a corresponding first antenna.
It should be noted that, the specific detection function of the signal detection unit 122 may be configured correspondingly according to the communication functions configured by the N first antennas 14, for example, when the communication signals corresponding to the communication functions configured by the N first antennas 14 are mainly reflected in the difference in signal frequency, the signal detection unit 122 may be configured with a frequency detection function; when the communication signals corresponding to the communication functions configured by the N first antennas 14 mainly represent the difference in signal power, a power detection function may be configured for the signal detection unit 122. Of course, the signal detection unit 122 may be configured with multiple signal parameter detection functions by default, and in practical applications, one or more of the detection functions may be selected according to actual requirements.
Thus, in the embodiment of the present application, the signal detection function can be realized by a simple antenna and signal detection unit structure, and it is ensured that the structure of the antenna switching device 100 is relatively simple and the implementation cost is low.
It should be noted that the external communication signal may refer to an external signal emitted by the antenna switching device 100 or an external communication device other than the electronic device provided with the antenna switching device 100, that is, a signal emitted by the non-antenna switching device 100 or the non-electronic device, and may be, for example, a signal emitted by a wireless base, an entrance guard device, a bus card swiping device, and the like near the antenna switching device 100.
In the embodiment of the present application, the N first antennas 14 are respectively configured to receive communication signals corresponding to different communication functions, and at least one parameter of the communication signals corresponding to the different communication functions may be different, that is, the receivable communication signals configured by the different first antennas 14 are different types of communication signals, and one or more index parameters that can be differentiated between the communication signals exist, for example, index parameters such as frequency, power, signal strength, and/or waveform of the communication signals that implement the different communication functions may be significantly different, so that in an actual application scenario, based on the performance of a detected external communication signal on a certain parameter, what communication function corresponds to the current communication signal may be differentiated, and which one or more first antennas 14 need to be activated.
The parameter of the external communication signal detected by the signal detection unit 122 may be one or more of at least one different parameter in the communication signals corresponding to different communication functions, for example, if the communication signals corresponding to different communication functions have a significant difference in frequency, the detected parameter may be frequency, that is, the target first antenna that needs to be activated in the current scenario may be determined by detecting the frequency of the external communication signal; for another example, if there is a significant difference in frequency and power between communication signals corresponding to different communication functions, the detection parameter may be frequency and/or power, that is, the target first antenna that needs to be activated in the current scenario may be determined by detecting the frequency and/or power of an external communication signal; for another example, if there is a significant difference in frequency and a significant difference in power in the communication signals corresponding to different communication functions, the detection parameters may be frequency and power, that is, the target first antenna that needs to be activated in the current scenario may be accurately determined by detecting the frequency and power of the external communication signal. That is, the parameters to be detected may be appropriately selected according to the parameters of the communication signal corresponding to the communication function actually configured by each first antenna 14.
Optionally, the signal detection module 12 determines whether the target communication signal is detected by detecting parameters of the external communication signal, the parameters including at least one of frequency, power, signal strength and waveform.
In one embodiment, the communication signals configured to be received by each first antenna 14 may have differences in parameters such as frequency, power, signal strength and/or waveform, so that one or more difference parameters may be selected accordingly as the parameters for detecting the external communication signals, and specifically, the detection parameters may include one or more of frequency, power, signal strength and waveform according to actual situations. Of course, the detection parameters may also include other parameters that can distinguish communication signals of different communication functions.
Optionally, the parameters comprise a plurality of frequencies, powers, signal strengths and waveforms;
the signal detection module 12 includes a plurality of signal detection units, and different signal detection units are respectively used for detecting different parameters of the external communication signal.
That is, in one embodiment, when the parameter includes a plurality of frequencies, powers, signal strengths, and waveforms, the signal detection module 12 may be configured with a plurality of signal detection units, each of which may correspond to a signal parameter detection function, for example, when the parameter includes a frequency, a power, and a waveform, the signal detection module 12 may include three signal detection units, one of which is used to detect the frequency of the external communication signal, one of which is used to detect the power of the external communication signal, and the other of which is used to detect the waveform of the external communication signal.
Through the embodiment, various parameters of the external communication signals can be detected, so that the communication function corresponding to the external communication signals can be more comprehensively and accurately distinguished, the corresponding signal detection unit can be used for detecting the external communication signals according to the parameters detected as required, and the flexibility and reliability of the signal detection mode are ensured.
In the embodiment of the present application, each first antenna 14 is gated to enter the working state through the switch 11, so that only one first antenna or a part of the first antennas is enabled in a scenario where a certain communication function is used, and thus mutual noninterference between the antenna paths corresponding to different communication functions can be ensured, and the antenna performance is improved. Accordingly, it is permissible to dispose the N first antennas 14 in the same physical space, for example, when the antenna switching apparatus 100 is disposed in an electronic device, the N first antennas 14 may be disposed in the same physical space in the electronic device.
That is, optionally, the N first antennas 14 are integrally provided in the same module.
Specifically, the N first antennas 14 may be stacked in the same physical space, or may be integrated in the same antenna module. In this way, compared to the conventional method in which a coil antenna is independently provided for each communication function in an electronic device, this embodiment can greatly optimize the device usage space by integrating a plurality of antenna loops, and can satisfy the requirement of integrating more communication functions in a small space, for example, multiple communication functions such as Radio Frequency Identification (RFID) of 125K, remote control key of 433MHz, RFID of 868MHz, wireless charging, and NFC of 13.65 MHz.
Optionally, the different communication signals include one or more of a first communication signal corresponding to a remote control function, a second communication signal corresponding to a near field communication, NFC, function, and a third communication signal corresponding to a radio frequency identification, RFID, function;
the first communication signal is a communication signal working at 433 MHz;
the second communication signal is a communication signal working at 13.56 MHz;
the third communication signal is a communication signal working at 125 KHz.
That is, in one embodiment, different first antennas of the N first antennas 14 may be respectively configured to receive a first communication signal corresponding to a remote control function, a second communication signal corresponding to an NFC function, a third communication signal corresponding to an RFID function, and the like, so that the electronic device configured with the antenna switching apparatus 100 can support one or more of the remote control function, the NFC function, and the RFID function, and the functions can be switched to implement operations without interfering with each other by switching independent antenna paths.
In addition, in order to distinguish the functions well, the operating frequencies of the communication signals corresponding to the functions may be configured, so that in practical applications, the types of the communication signals can be quickly and accurately identified by detecting the frequency of the external communication signal, and then the communication signals are quickly and accurately switched to the matched antenna path to support the current communication function. Specifically, the first communication signal may be a communication signal operating at about 433MHz, the second communication signal may be a communication signal operating at about 13.56MHz, and the third communication signal may be a communication signal operating at about 125KHz, so that a large frequency difference between the communication signals corresponding to different communication functions can be ensured, which is favorable for quickly identifying different communication signals from frequencies, and further, an antenna path corresponding to the corresponding communication function is enabled.
The antenna switching device in the embodiment of the application comprises: a switch; the signal detection module comprises a second antenna and a signal detection unit, one end of the signal detection unit is connected with the second antenna, and the other end of the signal detection unit is electrically connected with the first end of the change-over switch; the M communication modules are connected with the M second ends of the selector switch in a one-to-one correspondence mode, and M is an integer larger than 1; the N first antennas are connected with the N third ends of the selector switch in a one-to-one correspondence manner, and N is an integer greater than 1; the N first antennas are respectively used for receiving different communication signals, and at least one parameter of the different communication signals is different; when a target communication signal is detected by the signal detection module, outputting a switching signal to the switch, so that the switch gates a target communication module and a target first antenna, where the target first antenna is a first antenna used for receiving the target communication signal in the N first antennas, and the target communication module is a communication module matched with the target first antenna in the M communication modules; the first antenna of the N first antennas except the target first antenna is not communicated with any communication module of the M communication modules.
Therefore, the target first antenna which needs to be started currently can be determined by detecting the external communication signal, then the antenna is switched to the corresponding antenna access to receive the external communication signal, and other irrelevant antenna accesses are in a disconnected state, so that the corresponding antenna can be started according to actual requirements, interference among the antennas generated by starting multiple antennas simultaneously is reduced, and the working performance of the antenna is improved.

That is, in an embodiment, N parameter value intervals may be obtained in advance according to N parameter values of the communication signals configured by the N first antennas, for example, the parameter values of the communication signals configured by the 3 first antennas are C in order from large to small 1 、C 2 And C 3 Setting parameter value interval S 1 、S 2 And S 3 Wherein S is 1 Is greater than C 1 ' interval, S 2 Is greater than C 2 ' and is less than C 1 Interval of `, S 2 Is less than C 2 Interval of `, C 1 ' may be between C 1 And C 2 Value of between, C 2 ' may be between C 2 And C 3 A value in between. Of course, the parameter value interval may be defined according to other manners as long as the parameter values of different communication signals can be better distinguished.
In this way, after the measured value of the external communication signal is detected, which parameter value interval of the N parameter value intervals the measured value is located in can be determined, so that the first parameter value interval in which the measured value is located can be determined.
Then, a target communication signal with a parameter value in the first parameter value interval may be determined based on the first parameter value interval, where the target communication signal is a signal matched with the current external communication signal, and a first antenna used for receiving the target communication signal among the N first antennas may be further determined as a target first antenna.
Therefore, through the embodiment, the target first antenna matched with the current communication scene can be determined quickly and accurately by detecting the parameters of the external communication signals, and the antenna path corresponding to the target first antenna is gated through the selector switch 11, so that the target first antenna is enabled quickly, and good use timeliness is ensured.

When the working frequency spectrums of the communication function A, the communication function B and the communication function C are not crossed, the corresponding three frequencies are f (A) > f (B) > f (C), which communication function needs to be adopted can be judged by detecting the frequency points of the external communication signals, and the communication loop can be switched to the corresponding communication loop to complete communication.
For example, communication function a is a 433MHz remote control function, communication function B is a 13.56MHz NFC function, and communication function C is a 125K RFID function. When the frequency of an external communication signal is detected to be above 100MHz, the remote control function can be judged, so that an antenna configured for realizing the remote control function is started; when detecting that the frequency of an external communication signal is 1-100 MHz, judging the external communication signal as an NFC function, and starting and configuring an antenna for realizing the NFC function; and when detecting that the frequency of the external communication signal is lower than 1MHz, the RFID function can be judged, so that an antenna configured for realizing the RFID function is started. Thus, by switching to the corresponding antenna loop, the quality of the corresponding communication function can be improved.
Application scenario two: the communication function a and the communication function B have different driving strengths (i.e., power strengths), and are distinguished and determined by the signal power strengths.
The communication function a and the communication function B cannot be distinguished by frequency, but when the signal strength difference transmitted by the external communication device is large, different functions can be identified by power detection.
Specifically, the frequency of the communication function a is close to that of the communication function B, the signal strength of the communication function a is greater than that of the communication function B, and the communication function a can be determined when the signal strength induced by the external communication signal exceeds a set threshold, otherwise, the communication function B is determined.
For example, the communication function a is a wireless charging function, the signal frequency is 110kHz to 150kHz, and the transmission power is large; the communication function B is a 125K RFID function, the signal frequency is 125kHz or 134kHz, and the signal emission driving strength and the power are small. When wireless charging is used, the signal intensity of the detected wireless charging signal is far higher than that of the RFID, and the signal intensity can be used as a judgment basis.
Application scenario three: the other indices exhibited by the communication function a and the communication function B are different.
In this case, as long as there is a difference between the communication signals of the two communication functions, the corresponding communication function can be determined by detecting the difference index, and thus the communication function adaptation is realized.
