METHOD FOR INTELLIGENTLY SWITCHING ON/OFF MOBILE TERMINAL ANTENNA AND CORRESPONDING MOBILE TERMINAL

摘要

A method for intelligently switching on/off a mobile terminal antenna and a corresponding mobile terminal can improve antenna performance. A method comprises: detecting a current working frequency band and the surrounding environment of a terminal; according to preset correspondence between an antenna radiation unit, an environmental condition, and the current working frequency band, changing impedance characteristics of a parasitic unit radiator. Another method is: detecting a current working frequency band of a terminal; according to preset correspondence between an antenna radiation unit and the current working frequency band, changing impedance characteristics of a parasitic unit radiator. Another method is: detecting the current surrounding environment of a terminal; according to preset correspondence between an antenna radiation unit and an environmental condition, changing impedance characteristics of a parasitic unit radiator. The terminal comprises: a detection unit, an antenna control unit, and an antenna radiation unit. According to the technical solutions, the antenna radiation unit is controlled according to the working frequency band and/or the environmental state of the terminal, so as to improve communications quality of an air interface of a wireless communications system.
