With the development of mobile communication technology, people have higher and higher requirements on high speed, low time delay and high reliability of mobile networks in the high-speed requirements of games, video and audio and other scenes. The quality of the signal directly determines the quality of network experience, and the mobile phone integrates the antenna into a mobile phone metal shell in the compelling of pursuing beauty. Due to more and more frequency bands and more crowded mobile phone spaces, the mobile phone has two defects in using a built-in antenna, namely, the radiation efficiency of the antenna is low, and the efficiency is rapidly reduced due to the influence of hand holding. Under the scene that the signal is not good or the requirement on time delay is higher, the mobile phone signal is unstable, the communication delay phenomenon is obvious, and the user experience is not good.

The external antenna has the characteristics of wide bandwidth, high efficiency and no influence of hand holding. If the mobile phone is connected with an external antenna, the mobile phone signal can be greatly improved, better network experience can be obtained under weak signals, the power consumption of the mobile phone can be reduced, and the endurance of the mobile phone is more durable. Many attempts are made to improve the connection of the external antenna through an earphone hole or a USB interface, but due to impedance discontinuity of the interface, radio frequency signals cannot be effectively transmitted, and the effect of the actual external antenna is greatly reduced. The radio frequency coaxial connector used for common signal connection is an ideal switching interface, but has the problems of influencing the appearance, preventing the water of the mobile phone and the like, and is not suitable for the mobile phone. Therefore, how to connect the external antenna to the mobile phone for communication becomes a problem.
