초록

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 $50{\times}56.5{\times}5.5\;mm^3$이고, soft surface를 포함한 접지면의 크기는 $175.0{\times}154.4\;mm^2$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 GHB의 대역폭을 가지며, 각 대역의 중심 주파수에서의 이득은 10.63 dBi와 10.33 dBi이다.

In this paper, a dual band microstrip antenna with soft surface for gapfiller applications is proposed. The proposed antenna with similar radiation pattern and gain is fabricated on RO4003 substrate with a dielectric constant of 3.38 and a thickness of 0.508 mm, and operates in IEEE 802.11a/b bands. The size of the antenna is $50{\times}56.5{\times}5.5\;mm^3$ and the ground plane size including soft surface structure is $175.0{\times}154.4\;mm^2$. The antenna is fed by coaxial cable. The simulated bandwidths of the antenna are 2.388~2.493 GHz and 5.561~6.051 GHz for VSWR<2. The gains are 10.63 dBi and 10.33 dBi, respectively, for the lower and upper bands.
