【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。更多还原

【Abstract】 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.更多还原
