摘　　要：介绍了一种Ka波段和差馈电网络,由四级T形功分器、魔T级联形成。采用缝隙耦合的方式大大减小了横向与纵向尺寸,满足了天线整体小尺寸的要求。通过HFSS仿真优化,其输入端口的驻波系数小于1.14,与天线联合仿真和误差分析表明此馈电网络在加工精度内性能稳定,实测结果表明天线各项指标均得到满足。A design of sum and difference feeding network has been disigned in this paper,which consists of twenty six hybrid tee,Waveguide magic T and connection component.Small size has been received from using slot-coupling form.The network is simulated in HFSS,the vswr of input waveport is less than 1.14.The results of the network been simulated with antenna indicate the network is perfect for practical utility.

关 键 词：KA波段 功分网络 小尺寸
