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.

Abstract:

An antenna includes a ground plane having a slot. The slot may be miniaturized using a meandered slot structure or other appropriate reactive loading method as an end load to one or both ends of the slot. An edge treatment may be included on one or more edges of the ground plane or a closely spaced reflecting plane. The antenna is structured to transmit or receive a signal independently or in response to electromagnetic radiation.
