Abstract

This paper describes the design and analysis of five-element planar array antenna of an anti-jamming satellite navigation system. We propose a design of multi-layer patch antenna for Global Positioning System(GPS) $L_1/L_2$ dual bands. The proposed antenna has two ports feeding network with a hybrid chip coupler for a broad bandwidth with Right-Handed Circular Polarization(RHCP). The measurement results show the bore-sight gains of 1.10 dBic($L_1$) and 0.37 dBic($L_2$) for the center element. The bore-sight gains of an edge element are 0.99 dBic($L_1$) and -0.57 dBic($L_2$). At a fixed elevation angle of $30^{\circ}$, antennas show average gains of -2.08 dBic ($L_1$) and -5.33 dBic($L_2$) for the center element, and average gains of -0.40 dBic($L_1$) and -2.09 dBic($L_2$) for the edge elements. The results demonstrate that the proposed array antenna is suitable for anti-jamming applications.

본 논문은 재밍 대응 위성 항법 장치의 5소자 평면 배열 안테나 설계에 대해 기술한다. GPS $L_1/L_2$ 대역에서 공진하는 적층 구조의 패치 안테나 설계를 제안한다. 제안된 안테나는 광대역 및 원형 편파 특성을 구현하기 위해 칩 커플러를 이용한 이중 급전을 사용한다. 배열안테나 측정 결과, 중앙안테나의 전면 방향 이득은 $L_1$과 $L_2$ 대역에서 각각 1.10 dBic, 0.37 dBic, 측면안테나는 $L_1$과 $L_2$ 대역에서 0.99 dBic, -0.57 dBic를 갖는다. 고각 $30^{\circ}$에서 방위각의 이득은 중앙안테나 $L_1$과 $L_2$ 대역에서 평균 -2.08 dBic, -5.33 dBic의 측정 결과를 갖는다. 측면안테나는 $L_1$과 $L_2$ 대역에서 평균 -0.40 dBic, -2.09 dBic의 측정 결과를 갖는다. 제안된 5소자 평면 배열 안테나는 GPS 재밍 대응 장치에 적합함을 확인한다.
