In this embodiment, the target signal of the first feeder 1062 is the GPS L5 signal, and the WiFi-2.4GHz signal, which is an interference signal, is filtered by the filter 1064, so that the signal transmitted to the main control board of the mobile communication device 100 through the first feeder 1062 is only the GPS L5 signal of the target signal, thereby avoiding signal interference caused by simultaneous connection with two different radiation stubs.

It can be understood that, in the present embodiment, the signals transceived through the first radiation branch GD are WiFi-2.4GHz signals and GPS L5 signals. However, the embodiment of the present application does not limit the specific type of the signal for the first radiation branch GD to operate, and the signal may be a radio frequency signal of other types or other frequencies according to the frequency band to be supported by the mobile communication device 100.

In the present embodiment, the first feeder 1062 is connected to the point F, wherein the first radiating branch GD is used for receiving the GPS L5 signal, and the second radiating branch DF is used for receiving the N78 signal. In this embodiment, the target signal of the first feed line 1062 is the GPS L5 signal, and the N78 signal, which is an interference signal, is filtered by the filter 1064. Therefore, the signal transmitted to the main control board of the mobile communication device 100 through the first feeder 1062 is only the GPS L5 signal of the target signal, thereby avoiding signal interference caused by simultaneous connection with two different radiation branch lines.

In the embodiment of the present application, the second feeding line 1066 is connected to the point E, wherein the second radiation branch is used to receive signals in the N78 frequency band, and the third radiation branch ED is used to receive WiFi-5GHz signals.

Therefore, on the premise of only setting one breakpoint, the 5G antenna is further integrated, which is beneficial to the miniaturization of the mobile communication device 100 and ensures the structural strength of the mobile communication device 100, and on the other hand, covers more signal frequency bands and improves the communication performance of the mobile communication device 100.

Thus, the mobile communication device realizes the support of the GPS L5 signal through the first feeder 1062 and the GPS L1 signal through the third feeder 1068, thereby realizing the support of the dual-band GPS signal.

Meanwhile, a third feeder 1068 is connected to the point B, wherein the fifth radiation branch BC is used for receiving WiFi-2.4GHz signals, thereby implementing support for WiFi-2.4GHz signals.

Therefore, the mobile communication device supports the WiFi-5GHz signal through the second feeder 1066, and supports the WiFi-2.4GHz signal through the third feeder 1068, thereby supporting the dual-frequency WiFi signal.

Further, a third feed 1068 is connected to point B, wherein the second radiating branch DF is adapted to receive a signal in the N78 frequency band. Therefore, the communication device also supports 5G signals, so that the 5G antenna is further integrated on the premise that only one breakpoint is set and the dual-frequency GPS signal and the dual-frequency WiFi signal are simultaneously supported, which is beneficial to miniaturization of the mobile communication device 100, ensures structural strength of the mobile communication device 100, covers more signal frequency bands, and improves communication performance of the mobile communication device 100.
