Abstract

In this papar, we have proposed a small electronically steerable parasitic array radiator with 180 degree azimuth beam coverage and high gain characteristics. The proposed antenna is composed of a uniplanar Yagi dipole as a feeding element and two dipoles as parasitic elements. The fabricated antenna is tested by electronically changing the reactance loaded on the parasitic dipoles and the results show that it has 5.2dB~6.7dB gain in $-90^{\circ}{\sim}90^{\circ}$wide azimuth range and -10dB return loss characteristics within 5.725GHz~5.825GHz UNII band.

본 논문에서는 180도 방위 빔 커버리지 특성을 갖는 소형의 고이득 빔 조향 기생 배열 안테나를 제안한다. 이 안테나는 단일면 야기 다이폴 급전소자와 리액턴스가 장하된 인접한 두 기생 다이폴 소자로 구성되며 제작된 안테나는 기생소자의 리액턴스를 전자적으로 변화시킴으로써 UNII 대역에서 (5.725GHz~5.825GHz) 방위각$-90^{\circ}$에서 $90^{\circ}$범위에서 5.2dB~6.7dB 이득 특성을 가지며, 반사손실은 -10dB이하임을 측정을 통해 확인하였다.
