Zusammenfassung:Provided is a phase array antenna system which comprises an antenna dish including a plurality of antenna elements arranged in a thin array along a polygonal grid. The polygonal grid includes a plurality of paired polygons symmetrically arranged around the center polygon of the grid. In each polygon of the grid, the plurality of antenna elements are arranged in symmetrical pairs around the center point so that the first and second antenna elements are complex conjugations with each other. 안테나 접시는 다각형 그리드에 따라 얇은 어레이로 배치된 복수의 안테나 소자를 포함한다. 다각형 그리드는 그리드의 중심 다각형 주위에 대칭으로 배치된 복수의 쌍을 이룬 다각형을 포함한다. 그리드의 각 다각형에서, 복수의 안테나 소자는 각 대칭 쌍의 제1 및 제2 안테나 소자가 서로의 복소 공액이 되도록 중심점 주위에 대칭 쌍으로 배치된다.
