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