摘　　要：以毫米波制导为应用背景,研究平面微带结构的毫米波和差网络及收/发阵列的设计。使用ADS优化设计了微带分支耦合器,并用其搭建了一种结构紧凑的“十”字型和差网络,使用HFSS优化并仿真了4×4的微带矩形贴片阵列。和差网络和微带阵列组成单脉冲天线,采用HFSS仿真并分析了该阵列的和差方向图性能。Base on the application background of millimeter wave （MMW） guidance, the MMW sum-difference network and transmit/receive antenna array of the planar microstrip structure are analyzed. The compact cross shaped sum-difference network constituted by microstrip ramose couplers is optimized to design by ADS. While the 4 × 4 microstrip rectangular patches array is optimized to simulate by HFSS. The monopluse antenna is constituted by the sum-difference network and microstrip antenna array, and sum-difference directional diagram performance of the array is simulated to analysis by HFSS.
