    Abstract: 본 발명은 마이크로스트립 패치 배열 안테나에 있어서 안테나 인입선으로부터 배열된 패치들 사이에서 전력을 분배 또는 결합하기 위한 마이크로스트립 패치 배열 안테나를 위한 전력 분배/결합기에 관한 것이다.
    마이크로스트립 패치 배열 안테나를 위한 전력 분배/결합기는 기본적으로 원하지 않는 전자파의 방사없이 마이크로스티립 패치로 전력을 분배 또는 결합을 해주고, 안테나 인입선으로부터 마이크로스트립 패치까지 일정한 전기적 길이를 유지하여야 한다. 특히 전력 분배/결합기에서의 원하지 않는 전자파의 방사는 전체 안테나 방사 패턴의 변형을 유발하므로 전력 분배/결합기 설계시 상당한 주의를 요한다. 기존에 시용되던 T자 형태의 전력 분배/결합기는 구조가 간단하여 전력 분배/결합 및 일정한 전기적 길이 설계에는 용이하나, 마이크로스트립 선로상의 큰 불연속 구조를 가지므로 원하지 않는 전자파의 방사가 커지는 문제가 발생한다.
    따라서, 본 발명에서는 부드러운 곡선의 Y자 형태의 전력 분배/결합기를 설계하여 마이크로스트립 선로 상의 불연속을 줄여 원하지 않는 전자파의 방사를 방지하고, 전체 안테나 방사 패턴을 원하는 대로 유지할 수 있는 마이크로스트립 패티 배열 안테나 제작을 가능하게 한다.
