ABSTRACT:
A method and apparatus for controlling a beam switching antenna system of a mobile communication terminal, the method includes forming a beam; determining whether an earphone is connected to the mobile communication terminal; and controlling the formed beam to have non-directivity if the earphone is connected to the mobile communication terminal. The apparatus for controlling a beam switching antenna includes a signal source for supplying the antenna element with a signal to form the beam; and a controller for controlling the ground switch to apply the reference voltage to the at least one conductive reflector, to thereby imparting the formed beam with a predetermined beam pattern.
