1. A coplanar antenna unit, comprising:
- a substrate;
a radiation plane disposed on a first side of the substrate, and comprising;
a feed plane receiving a feed-in signal, and the feed-in signal generating a radiation signal at the feed plane; and
an output plane having an interval from the feed plane, and the radiation signal being coupled to the output plane, and the output plane outputting the radiation signal, and the output plane including a first extension portion and a second extension portion;
a first ground plane disposed on the first side of the substrate, and situated on a first side of the radiation plane, and the first ground plane having a first hollow portion, and the first extension portion being disposed in the first hollow portion, and an end of the first extension portion being coupled to the first ground plane;
a second ground plane disposed on the first side of the substrate, and situated on a second side of the radiation plane, and the second ground plane having a second hollow portion disposed at a position corresponding to the first hollow portion, and the second extension portion being disposed in the second hollow portion, and an end of the second extension portion being coupled to the second ground plane; and
a metal plate disposed on a second side of the substrate, and the metal plate being disposed corresponding to the radiation plane.

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.
