ANTENNA HAVING REAR CHOKE REFLECTOR AND APPARATUS FOR REFLECTING IN ANTENNA

摘要

PURPOSE: An antenna with a rear choke reflector and a reflecting device for an antenna are provided to vertically install a reflecting plate of a directivity antenna, thereby increasing a front/back ratio. CONSTITUTION: An electric wave radiating element(110) emits an electromagnetic wave. A reflecting plate(120) is arranged in the rear part of the electric wave radiating element. The reflecting plate reflects an electric wave which is radiated backward. A rear choke radiator(140) is arranged in the rear side of the reflecting plate. The rear choke radiator is vertical to the reflecting plate.
