Abstract

This paper proposes an small electronically steerable parasitic array radiator composed of a uniplanar dipole as a feeding element and two dipoles as parasitic elements. The fabricated antenna shows by measurement the $3.3{\sim}4.3\;dB$ gain between $-100{\sim}1000$ azimuth range in the dipole vertical plane and -10 dB return loss within $5.4{\sim}5.9\;GHz$, which includes $5.725{\sim}5.825\;GHz$ UNII band.

본 논문에서는 단일면 야기 다이폴 급전 소자와 리액턴스가 장하된 인접한 두 기생 다이폴 소자를 이용한 UNII 대역에서 동작하는 소형 빔 조향 평면형 다이폴 배열 안테나를 제안한다. 제작된 안테나는 기생 소자의 리액턴스를 전자적으로 변화시킴으로써 UNII 대역에서($5.725{\sim}5.825\;GHz$) 다이폴 수직면 $-100^{\circ}$에서 $100^{\circ}$ 범위에서 $3.3{\sim}4.3\;dB$ 이득 특성을 갖고, -10 dB 이하 반사 손실 대역폭은 $5.4{\sim}5.9\;GHz$로 UNII대역을 포함함을 측정을 통해 확인하였다.
