Abstract
The present invention relates to a planar composite right/left handed (CRLH) antenna, comprising: a substrate body which is made of dielectric materials, and which has a planer structure; a radiation line which is disposed on one side of the substrate body, and which is bent to form a slot for exposing a predetermined width of the substrate body through both ends thereof, and which resonates at a predetermined frequency band when fed; and a feeder line which is disposed on the outer side of the substrate body, which extends across the slot, and which feeds electric power to the radiation line. The planar CRLH antenna of the present invention is small in size, and expands a radiation area, thereby expanding an available frequency band, or using a dual frequency band.
