Abstract

This paper presents the design and fabrication of a shaped-beam array antenna which will be used for a PCS basestation using structure that is coupled to a microstrip line by an aperture on the intervening ground plane. The shaped-beam pattern is obtained by an antenna synthesis method. An array antenna considering the mutual coupling between array elements(patches) and a feeding network are designed by CAD tools. The feeding network is designed by using the Wilkinson power divider to obtain the optimized shaped-beam. The designed results are compared with the measured data.

본 논문에서는 그라운드면 상의 개구를 통해 마이크로스트립 패치로 결합을 일으키는 구조를 갖는 PCS 기지국용 정형 빔 배열 안테나 설계와 제작에 관하여 다룬다. 최적의 정형 빔 패턴은 안테나 합성법으로 얻어졌다. 배열된 패치들 사이에서의 결합을 고려한 배열 안테나와 급전회로는 CAD tool을 이용하여 설계되었다. 급전 회로는 최적의 정형 빔 패턴을 얻기 위해서 Wilkinson 전력 분배기를 이용하여 설계되었다. 설계 결과와 측정 결과가 비교되어진다.
