-
摘要: 用口径场的方法对有限长同轴双锥天线进行了分析和设计。同轴双锥天线能工作在电压±100kV、重复频率100Hz、单周期脉冲全底宽3.6ns和输出阻抗50Ω的超宽带脉冲辐射源上，辐射功率大于100MW；天线带宽150MHz～1GHz；输入阻抗50Ω。E平面和H平面平行极化半功率点全宽度分别为50°和360°；天线的功率效率约为65%。Abstract: The radiation fields and the design of coaxial biconical antenna are obtained with the field of equivalent Huggens source on the spherical surface aperture. The experiment of high power coaxial biconical antenna which has been operated in ultrawide band pulse of high voltage ±100kV, high repetition rate 100Hz, pulse duration 3.6ns, and the radiation peak power more than 100MW are also presented. The antenna band wide is from 15MHz to 1GHz，input impedance 50Ω; The FWHM of an tenna patterns for peak power in E plane and H plane is 50° and 360°, respectively, radiation efficiency more than 65%.
