1 THE JOURNAL OF KOREAN INSTITUTE OF ELECTROMAGNETIC ENGINEERING AND SCIENCE Sep.; 27(9), ISSN (Print) ISSN X (Online) GPS Design of Dual-Band GPS Antenna Using a Single-Layer Coupled-Feed Structure 허준 변강일 추호성 계영철 Jun Hur Gangil Byun* Hosung Choo Youngchul Kay 요약 GPS.,.., 3 db, 2 db CRPA. Abstract In this paper, we propose a dual-band GPS antenna using a single-layer coupled-feed structure for improvement of isolation and design complexity. The proposed antenna consists of a central feed patch and outer dual loops, and the loops are electromagnetically fed by the feed patch to induce currents. This feeding network can improve the isolation between antenna elements arranged in small arrays because the magnetic field strength near the antenna is minimized by confining the fields around the dual loops. The isolation characteristics of the proposed antenna are compared with those of the conventional multi-layer patch antenna, and the average field strength and the isolation are improved by 3 db and 2 db, respectively, which verifies that the antenna is suitable for small CRPA arrays. Key words: GPS Array, CRPA Array, Coupled Feed, Isolation. 서론 CRPA(Controlled Reception Pattern Antenna) null [1] [3].
