Abstract

In this paper, a meander-type microstrip patch antenna for application in 5GHz-band is designed and fabricated. To obtain enough bandwidth in VSWR<2, the foam is inserted between substrate and ground plane, the coaxial probe source is used. Antenna is simulated varing the length and width of meander line, the position of probe feeding and the thick of airgap. Later anterlna is fabricated with optimizated antenna parameter. The measured result of Fabricated antenna obtained $1GHz(17.5\%)$ bandwidth in VSWR<2$, the gain of $.3\sim9.5$dBi, Unidirectional pattern.

본 논문에서는 5GHz 전 대역에서 사용 가능한 미앤더 형태의 마이크로스트립 안테나를 설계하고 제작하였다. 미앤더 형태의 안테나에 공기층을 삽입하고 동축 급전을 주어 VSWR<2에서 충분한 대역을 얻고자 하였다. 미앤더 라인의 길이와 폭, 동축급전의 위치 및 공기층의 두께를 변화시키면서 시뮬레이션 하였으며, 최적화된 파라미터를 가지고 안테나를 제작하였다. 제작된 안테나의 측정 결과는 VSWR<2에서 약 1GHz의 $17.5\%$의 대역폭을 얻었으며, $7.3\sim9.5$ dEi의 이득과 Broad한 방사패턴을 얻었다.
