Antenna for controlling radiation direction
First Claim
Patent Images
1. An antenna comprising:
- a first substrate;
a first radiator formed at one surface of the first substrate;
a second radiator formed at another 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 a control signal;
a second substrate which contacts the first substrate in a direction by which the second radiator is formed;
a ground layer formed in a surface of the second substrate; and
a feed line penetrating the second substrate and connected to the second radiator,wherein each of the first and the second radiators are formed as a patch in the one and the other surfaces of the first substrate.

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.
