In the embodiment of the invention, under the condition that the switch module is in the first working state, the trap network can guide the harmonic signal of the WiFi antenna channel into the ground, so that the harmonic generated when the WiFi antenna channel works can be effectively prevented from being radiated out through the first antenna, and the interference on the mobile communication network antenna can be greatly reduced; meanwhile, under the condition that the switch module is in the second working state, the target antenna path and the WiFi antenna path are both connected with the first antenna, so that the target antenna path and the WiFi antenna path can work simultaneously, and thus the target antenna path and the WiFi antenna path can realize common antenna design, and further the space occupied by the antenna can be saved.
Optionally, the switch module is in the first working state under a condition that the WiFi antenna path 107 and the mobile communication network antenna of the electronic device are both in working states.
For the convenience of understanding the present embodiment, the following is exemplified:
assuming that the mobile communication network antenna of the electronic device is an n79 antenna, the WiFi antenna path 107 of the electronic device is a WiFi2.4g antenna path, and the number of the target antenna paths 105 and the first connection points 102 is two, wherein one of the target antenna paths 105 is a GPS antenna path, the GPS antenna path is connected to one of the first connection points 102, the other one of the target antenna paths 105 is a WiFi5G antenna path, and the WiFi5G antenna path is connected to the other one of the first connection points 102, the operating state of the switch module can be referred to fig. 2. As shown in fig. 2, the switch module is in the first operating state only when it is determined that n79 of the electronic device is registered, that is, the n79 antenna is in an operating state, and it is determined that the electronic device is in a wifi2.4g networking state or in a wifi2.4g hotspot opening state, that is, the wifi2.4g antenna pathway 107 is in an operating state; otherwise, the switch module is in other working states, where the other working states may include a working state in which the common terminal 101 of the switch module is connected to each connection point separately, or a working state in which the common terminal 101 of the switch module is connected to more than one connection point simultaneously.
Because only under the condition that the WiFi antenna path of the electronic equipment and the mobile communication network antenna are both in working states, the switch module is in the first working state, and therefore loss generated by the operation of the trap network can be reduced.
Optionally, the switch module is in the first operating state when the WiFi antenna path 107 and the mobile communication network antenna of the electronic device are both in the operating state, and the voltage of the WiFi signal of the WiFi antenna path 107 is greater than a preset voltage threshold.
The WiFi signal of the WiFi antenna path 107 may refer to the WiFi signal transmitted by the WiFi antenna path 107 to the first antenna 108.
The preset voltage threshold may be a voltage corresponding to a WiFi signal of the WiFi antenna path 107 when a harmonic generated by the operation of the WiFi antenna path 107 interferes with the mobile communication network antenna or generates a large interference; that is, in this case, when the voltage of the WiFi signal of the WiFi antenna path 107 is greater than the preset voltage threshold, the harmonic generated by the operation of the WiFi antenna path 107 may generate interference or generate large interference to the mobile communication network antenna, and when the voltage of the WiFi signal of the WiFi antenna path 107 is less than or equal to the preset voltage threshold, the harmonic generated by the operation of the WiFi antenna path 107 may not generate interference or generate large interference to the mobile communication network antenna.
Because only when the WiFi antenna access of the electronic equipment and the mobile communication network antenna are both in working states and the voltage of the WiFi signal of the WiFi antenna access is greater than the preset voltage threshold value, the switch module can be in the first working state, and therefore the loss caused by the operation of the trap network can be further reduced.

The conduction control signal may be used to instruct to conduct the first connection arm and the second connection point 103.
Because the judgement module can follow the wiFi signal of public end collection to under the circumstances that the voltage of judging the wiFi signal is greater than predetermineeing the voltage threshold and receive the control signal that switches on that the controller sent, control first tie arm and second tie point and be connected, thereby make the switch module only be in operating condition at electronic equipment's wiFi antenna route and mobile communication network antenna, and under the circumstances that the voltage of the wiFi signal of wiFi antenna route is greater than predetermineeing the voltage threshold, just can be in first operating condition, like this, can further reduce the loss that notch network work produced.

in case the antenna arrangement comprises the third phase shifting network 1012, the first end of the notch network 106 is connected to the second connection point 103 via the third phase shifting network 1012; the third phase shifting network 1012 is configured to allow harmonic signals of the WiFi antenna path 107 to pass through and block the target signal of the target antenna path 105 and the WiFi signal of the WiFi antenna path 107 from passing through.
The first phase shifting network 1010 is configured to allow the WiFi signal of the WiFi antenna path 107 to pass through, and block the target signal of the target antenna path 105 and the harmonic signal of the WiFi antenna path 107 from passing through, which can be specifically understood as: the first phase shifting network 1010 presents a low impedance to the WiFi signal and a high impedance to the target signal and the harmonic signal. Here, low impedance may be understood as impedance smaller than a first value, high impedance may be understood as impedance greater than or equal to a second value, which may be greater than the first value.

Because the first phase shifting network is used for allowing the WiFi signal of the WiFi antenna access to pass through and blocking the target signal of the target antenna access and the harmonic signal of the WiFi antenna access from passing through, the target signal of the target antenna access and the harmonic signal of the WiFi antenna access are difficult to enter the WiFi antenna access, and thus, the isolation of the target signal of the target antenna access and the harmonic signal of the WiFi antenna access by the WiFi antenna access can be improved, and the interference on the WiFi signal of the WiFi antenna access can be effectively reduced.
The second phase shifting network is used for allowing the target signal of the target antenna access to pass through and preventing the WiFi signal of the WiFi antenna access and the harmonic signal of the WiFi antenna access from passing through, so that the WiFi signal of the WiFi antenna access and the harmonic signal of the WiFi antenna access are difficult to enter the target antenna access, the isolation of the target antenna access to the WiFi signal and the harmonic signal of the WiFi antenna access can be improved, and the interference on the target signal of the target antenna access can be effectively reduced.
The third phase shifting network is used for allowing the harmonic signals of the WiFi antenna access to pass through and blocking the target signals of the target antenna access and the WiFi signals of the WiFi antenna access from passing through, so that the target signals of the target antenna access and the WiFi signals of the WiFi antenna access are difficult to flow to the notch network, the isolation of the notch network to the target signals of the target antenna access and the WiFi signals of the WiFi antenna access can be improved, and the target signals of the target antenna access and the WiFi signals of the WiFi antenna access can be better prevented from being led into the ground.

and N is a positive integer greater than 1.
Because the number of the target antenna access and the number of the first connecting points are both N, and N is a positive integer greater than 1, the common antenna design of more target antenna accesses and WiFi antenna accesses can be realized, and thus, the space occupied by the antenna can be further saved.
Optionally, the WiFi antenna path 107 is a WiFi2.4G antenna path;
