Abstract

In this paper, we propose the design of a dual-band GPS antenna using in-direct feeding pads. The antenna consists of an upper patch for the GPS L1 band, a lower patch for the GPS L2 band, and two pads on the middle layer for feeding the two radiating patches. A hybrid chip coupler with a phase difference of $90^{\circ}$ is employed at the two feeding ports for achieving a broad circular polarization (CP) bandwidth. The proposed antenna shows bore-sight gains of 3.0 dBic(L1) and 5.1 dBic(L2), and axial ratios of 3.3 dB(L1) and 0.3 dB(L2) by measurement. The active element patterns of the fabricated array with 7 elements show bore-sight gains of -0.4 dBic (L1) and -2.4 dBic(L2), respectively. It proves that the proposed antenna structure is suitable for use in GPS array applications.

본 논문에서는 간접급전 패드를 이용한 이중 대역 GPS 패치 안테나를 제안하였다. 제안된 안테나는 GPS L1 대역에서 공진하는 상부패치, L2 대역에서 공진하는 하부패치, 중간층에 위치하는 2개의 간접급전 패드로 구성되며, 광대역 원형 편파 특성구현을 위해 하이브리드 칩커플러를 사용하여 두 급전 포트 사이에 $90^{\circ}$의 위상차를 갖도록 급전하였다. 제안된 개별 안테나의 측정 결과, 전면 방향 이득은 GPS L1, L2 대역에서 각각 3.0 dBic, 5.1 dBic를 나타내며, 축비 특성은 각각 3.3 dB, 0.3 dB를 나타내는 것을 확인하였다. 제안된 안테나를 동일한 유전체 기판 가장자리에 7소자 배열하여 제작하여 active element pattern을 측정한 결과, 전면 방향 이득은 GPS L1, L2 대역에서 각각 -0.4 dBic, -2.4 dBic를 나타내어 GPS 배열안테나의 개별 소자로 사용 가능함을 확인하였다.
