Abstract

Embodiments of the invention provide an antenna detection method. The method is applied to a mobile terminal; the mobile terminal includes multiple antenna modules and a directional coupler arranged in a transmit-receive path; the standing-wave ratio of each target antenna module can be obtained during the processing of switching antennas; and the target antenna modules are abandoned if the register values of the antenna modules are not correct under the circumstance that the standing-wave ratio of one target antenna module is larger than a set threshold value. Thus, for the mobile terminal ofmultiple antennas, the method for detecting the damaged antennas is simple, and therefore, the continuous switching and trying of the damaged antennas can be avoided, the performance and stability ofa system can be improved, and system resources can be saved.

Description

technical field [0001] Embodiments of the present invention relate to the field of mobile terminals, and in particular, to an antenna detection method, an antenna detection device, and a mobile terminal. Background technique [0002] At present, mobile terminals mostly use dual antennas to transmit and receive signals, but in the face of increasingly complex electromagnetic environments and usage scenarios, dual antennas are gradually becoming inadequate. Therefore, multi-antennas emerge as the times require, but multi-antennas will bring a risk of damage to the antenna tuner, which not only causes performance degradation, but also may affect the normal operation of the mobile terminal. [0003] For a mobile terminal with dual antennas, in the prior art, it is judged whether the currently used antenna will be restricted by detecting the strength of the signal received by the antenna, and if it is restricted, another antenna is switched to use. Refer to the specific dual-ant...
