摘　　要：天线馈源网络插入损耗的传统测量方法忽略了馈源喇叭损耗的贡献.为了精确测量天线馈源网络的插入损耗,本文提出了用标准喇叭增益比较法确定天线馈源网络插入损耗的一种新方法.利用功率传输方程,推导了天线馈源网络插入损耗测量的原理方程,简述了其测量的方法程序.分析了失配误差对天线馈源网络插入损耗测量的影响,计算了失配误差修正曲线.最后,给出了一个Ka波段圆极化馈源网络插入损耗测量结果,测量结果满足馈源网络插入损耗的技术要求,从而验证了该方法的可行性.Traditional measurement methods of antenna feed network insertion loss neglect contribution of the feed horn loss.In order to measure exactly insertion loss of antenna feed network,a new method for measuring antenna feed network insertion loss is presented using compared method of standard gain horn.Principle equation of antenna feed network insertion loss is derived using power transmission equation,and test procedure is described simply.It is analyzed that effect of mismatched error on antenna feed network insertion loss measurement.At fast,measuring results of insertion loss are given for Kaband circular polarization feed network,measuring results meet technique requirement of the feed network insertion loss,and feasibility of the method is verified.The paper has importance reference value of insertion loss measurement of antenna feed network.
