Coplanar antenna unit and coplanar antenna

Abstract

The present invention is related to a coplanar antenna unit and a coplanar antenna. By utilizing the unique properties of meta-material to design 1-D balanced CRLH leaky-wave antenna. The antenna can be realized with the coplanar antenna unit consisting of MIM capacitor and grounded inductor. In this invention, all proposed elements are implemented by planar print circuit broad, so the full-space switched beam scanning antenna has shorter length of leaky-wave antenna and good radiation performance.
