Abstract:
Provided is a method for matching antenna impedance in a wireless communication system. The method includes determining an approximate reflection coefficient based on an input signal and an output signal of a bidirectional coupler connected to a signal path of an antenna; determining an antenna impedance matching parameter corresponding to the determined approximate reflection coefficient by using a lookup table; and performing antenna impedance matching based on the antenna impedance matching parameter.
