Mobile terminal antenna multiplexing system and control method thereof and mobile terminal

Abstract

The present invention discloses a mobile terminal antenna multiplexing system and a control method thereof and a mobile terminal. The mobile terminal antenna multiplexing system comprises a radiatingbody, multiple antenna accesses, a CPU processor and a radio frequency module, each antenna access comprises one feed point, one matching module and one switching module. The antenna radiating body ofthe mobile terminal is provided with a plurality of feed points, each feed point is connected with one switch, the each feed point is provided with one independent matching circuit, the mobile terminal controls the on-off switch of the switch through the CPU processor according to the concrete application demand and the environmental state of the mobile terminal so as to change the resonant frequency of the corresponding antenna, corresponding antenna accesses are selected through the radio frequency modules to achieve antenna multiplexing. On the premise without increasing the number of themobile terminal antennas, the mobile terminal antenna radiators can be more intelligently and reasonably utilized, and the frequency coverage and the receiving and transmission performances of the mobile terminal antennas are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal antenna multiplexing system, a control method and a mobile terminal thereof. Background technique [0002] With the advent of the 5G era, the demand for antennas in the field of mobile terminals is also increasing, which is specifically reflected in the need for wider coverage frequencies and more antennas. However, the design space of the terminal antenna has not increased. On the contrary, the current popular design schemes such as full screen and all-metal back cover further reduce the design space of the antenna and deteriorate the antenna radiation environment. However, in the case where the mobile communication frequency does not change Under the circumstances, it is unrealistic to greatly increase the number of antennas on the mobile terminal. At present, the commonly used antenna multiplexing scheme includes antenna tuning, but there are f...

However, the design space of the terminal antenna has not increased. On the contrary, the current popular design schemes such as full screen and all-metal back cover further reduce the design space of the antenna and deteriorate the antenna radiation environment. However, in the case where the mobile communication frequency does not change Under the current situation, it is unrealistic to greatly increase the number of antennas on the mobile terminal. At present, the commonly used antenna multiplexing scheme includes antenna tuning, but there are few schemes that use multiple feed points to multiplex antennas.
