ABSTRACT:
A beam switching antenna system and method and apparatus for controlling the same is provided, by which optimal antenna characteristics can be maintained according to a peripheral environment, the necessary time and power consumption of searching an optimal beam-direction can be reduced, and electromagnetic waves of a beam generated from an antenna can be minimized. The beam switching antenna system includes an antenna element for transmitting and receiving a beam; a dielectric body surrounding said antenna element; at least one conductive reflector facing a lateral outside of said dielectric body; and a ground switch circuit connected to said at least one conductive reflector. The ground switch circuit includes a reference voltage source generating a reference voltage; a ground line connected to the reference voltage source; an electrical switching device connected between the ground line and the conductive reflector; and a controller for controlling the electrical switching device. The conductive reflector includes an upper conductive reflector having one end connected to one terminal of the electrical switching device; and a lower conductive reflector having one end connected to another terminal of the electrical switching device and the other end connected to the ground line.
