摘要
笼形结构通过等效加粗导线直径可降低甚低频T形发射天线的特性阻抗,改善输入阻抗特性,展宽天线工作带宽。文章采用矩量法计算了笼形与线形两种甚低频发射天线结构、不同笼直径、不同顶线长度天线的输入阻抗特性,并进行了分析对比。
The wire diameter of VLF T-type antenna can be equivalently increased by using cage structure. teristic impendence and bandwidth of the antenna can be improved and extended. The both input impendence of tenna with cage and liner two ferent length of the top wire. structures are calculated based on method of moment for different diameters of the And the results are compared and analyzed. The charaethe VLF ancage and dif
