摘　　要：馈源是紧缩场主要部件之一,对紧缩场的电气性能有很大影响。目前国内外设计的紧缩场低频馈源,通常采用金属圆锥喇叭的形式,造成馈源体积、重量较大,不易测试使用。本文提出一种新的馈源结构,由金属脊喇叭加载一个介质阻抗壁构成,经优化减小了馈源的体积和重量。最后,仿真和测试结果表明了这种馈源结构的可行。Feeds are important to electric performance of compact range as one of its main parts. Generally, metallic horn is adopted as the structure of the feed, and the feed is extremely large and heavy. A novel horn feed composed of metallic ridged horn and dielectric impedance wall which has small dimension and weight is introduced. The simulation of the feed is presented and test results show its availability.
