Title
(EN) Antenna detection method and device, and mobile terminal
(ZH) 一种天线检测方法、天线检测装置及移动终端
Abstract
(EN)
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.
