Abstract
An antenna for controlling a radiation pattern includes a first substrate; a first radiator formed in one surface of the first substrate; a second radiator formed in other surface of the first substrate; and a tuning part which controls a radiation pattern by changing a size of an overlapping region of the first radiator and the second radiator disposed with the first substrate interposed therebetween according to an external control signal. The tuning part includes a plurality of sub-radiators arranged by at least one side of the first radiator or the second radiator, and a plurality of switches. Accordingly, the beam radiation pattern can be easily controlled through the switch control.
