초록

본 논문에서는 저고도각 고이득 특성을 이용한 3 소자 CRPA 배열 안테나 설계를 제안하였다. 제안된 안테나는 급전패치와 방사패치로 구성되어 있으며, 급전패치에 동축케이블을 통해 급전부가 직접 연결되고 방사패치에 전자기적으로 간접급전되어 저고도각 이득 특성이 개선되는 구조를 가진다. 제안된 배열안테나의 성능 측정을 전파무반사실에서 수행하였으며, 전면 방향 이득은 2.8 dBic, 축비 특성은 2.7 dB, $75^{\circ}$의 저고도각 평균 이득이 -1.4 dBic를 나타내어 항재밍 성능을 갖는 CRPA 안테나로 적합함을 확인하였다.

In this paper, we propose a three-element CRPA array with improved low-elevation gain. The proposed antenna consists of a feed patch and a radiating patch, and the feed patch is connected by a coaxial cable. The radiating patch is electromagnetically coupled to the feed patch, which allows to improve the low-elevation gain of the antenna. To demonstrate the suitability of the proposed antenna, the antenna characteristics are measured in a full anechoic chamber. The resulting bore-sight gain is 2.8 dBic with an axial ratio of 2.7 dB, and the average gain at the low-elevation direction of $75^{\circ}$ is -1.4 dBic. The results verify that the proposed antenna is suitable for CRPA arrays with anti-jamming capability.
