Abstract:
1. A direction control antenna comprising: a ground body; a radiator that radiates a radio frequency (RF) signal and that is used as a direction control element of the direction control antenna, wherein a stub is formed at an edge of the radiator and a shape of the radiator is symmetrical; a plurality of impedance elements that are connected between the radiator and the ground body; a plurality of switches that are connected between each impedance element and the ground body; and a controller that controls on/off of the plurality of switches according to a control instruction from the outside, wherein a radiation direction and a radiation form are determined according to a short circuit position of the radiator that is short-circuited to the ground body and the number of short circuit positions by the turned-on switch, wherein the direction control antenna is capable of beaming radiation omni-directionally.
