Abstract

Our new metamaterial structure patch antenna improves the gain of ordinary metamaterial patch antenna. The structure of new metamaterial cover is made by removing central $7{\times}7$ lattices out of $9{\times}9$ lattices. Also, the metamaterial covers can be easily fabricated using ordinary substrates. Measurement results of a patch antenna, a metamaterial patch antenna and our proposed metamaterial patch antenna show that the gain of the proposed metamaterial patch antenna is about 3dB higher than that of the ordinary metamaterial patch antenna.

새로운 메타매터리얼 구조 패치안테나는 기존 메타매터리얼 패치안테나의 이득을 개선하였다. 새로운 메타매터리얼 커버의 구조는 $9{\times}9$ 격자 중에서 중심을 기준으로 $7{\times}7$격자를 제거하는 구조로 만들었다. 또한 그 메타매터리얼 커버는 보통 기판을 사용하여 쉽게 제작이 가능하다. 패치안테나, 메타매터리얼 패치안테나, 제안된 메타매터리얼 패치안테나의 결과를 비교해 보았으며, 비교한 결과 제안된 메타매터리얼 패치안테나는 보통 메타매터리얼 패치안테나보다 약 3dB 더 좋은 결과를 보였다.
