摘　　要：理论分析矩形栅格与三角形栅格平面相控阵天线的辐射方向图、扫描角与栅瓣位置、阵元间距及辐射单元，以某工程为例，采用介质填充技术设计了Ka频段高增益、低旁瓣具有±60°大扫描角的相控阵天线，分析计算不同扫描角的辐射性能。实测结果验证了理论设计的正确性与工艺可实现性。The differences of radiation pattern, scanning angle, grating lobe positions, the element spacing and radiation unit between rectangular grid array and triangular grid are discussed theorectically. Take a project as an example, the high gain and low sidelobe phased array antenna with ±60°scanning angle on Ka band is designed by using medium filling technique, the radiation performance of differenct scanning angle are calculated and the testing results verify the correctness of theoretical design and the process feasibility.
