Abstract
본 논문에서는 soft surface를 이용하여 IEEE 802.11a/b 대역에서 10 dBi 이상의 이득과 유사한 모양의 복사 패턴과 이득을 가지며, 동작하는 신호 중계 장치용 안테나를 제안한다. 제안한 안테나의 크기는 50×56.5×5.5 mm3이고, soft surface를 포함한 접지면의 크기는 175.0×154.4 ㎟이다. 안테나는 동축 케이블을 이용하여 급전하였으며, 두께가 0.508 mm이고 비유전율이 3.38인 RO4003 기판 위에 설계하였다. 전산 모의 실험 결과, VSWR<2 기준으로 2.388∼2.493 GHz와 5.561∼6.051 GHz의 대역폭을 가지며, 각 대역의 중심 주파수에서의 이득은 10.63 dBi와 10.33 dBi이다.
