Abstract
The present invention provides a method and an apparatus for compensating frequency shifting of an antenna, applicable to a wireless communication device having at least one frequency shifted operating mode, in which a frequency shifting exists due to a variation of a device use mode or an environmental condition, wherein the method comprises setting in the antenna at least one compensation matching circuit corresponding to the at least one frequency shifted operating mode; detecting the use mode, in which the wireless communication device operates; when the wireless communication device is in the frequency shifted operating mode, switching to a compensation matching circuit corresponding to the frequency shifted operating mode as detected. In the present invention, the difficulty in the bandwidth design of the antenna is reduced, and the effect of the variation of the use mode or environmental condition on the performance of the antenna is compensated adaptively.
