Problems solved by technology

[0007] The disadvantage of the above-mentioned prior art is that the wireless signal transmitting and receiving antenna of the Beidou navigation system and the 5G wireless signal transmitting and receiving antenna are independent, and the above two antennas work on two different frequency points to complete the tasks of transmitting and receiving signals of different frequencies. The independent antenna not only causes excessive energy consumption of the system, but also increases the volume of the system for the mobile terminal, which brings great inconvenience to users
