Abstract

The embodiment of the invention provides an antenna switching method and device and a mobile terminal. Various performance indexes of a first antenna and a second antenna arranged on a terminal are detected; specifically, the performance indexes indicate receiving sensitivity; whether the detected performance indexes satisfy a preset switching condition or not is judged; if the preset switching condition is satisfied, the terminal is switched from a first working state to a second working state; when the terminal is in the first working state, the terminal receives a signal only through the first antenna, and the second antenna does not receive the signal; and when the terminal is in the second working state, the terminal receives the signal through the second antenna. The receiving sensitivity of the antennas is judged, so the receiving capabilities of the two antennas for the signal are determined. Weather the first antenna satisfies the preset switching condition or not is judged, and the antenna switching operation is carried out according to a judgment result, so the signal receiving capability of a mobile phone can be maximized in different scenes, and the performance that the backup antenna has relatively high directionality gain is utilized fully.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to an antenna switching method and device, and a mobile terminal. Background technique [0002] In recent years, smart phones have developed rapidly, especially in the 4G era, LTE (Long Term Evolution, long-term evolution) has become a standard configuration, and the commercialization of 4G+ is also rapidly approaching. Carrier aggregation technology has become the next generation of smart phones. Technology hotspot. [0003] Existing antenna solutions In the current multi-mode and multi-frequency mobile phone solutions, it is extremely difficult to design mobile phone antennas due to the fact that multiple frequency bands are concentrated on one antenna or two antennas, and there is not enough antenna area and clearance area in the structure. Carrier aggregation technology adds combiners and multiplexers to the radio frequency circuit, the insertion loss of the ...
