The Traveling-Wave Characterisics of A Disc Reflector-Loaded Monopole Antenna

本文论述了具有圆盘反射器的单极天线,在双曲加载状态下,由同轴线中心导体激励时的基本特性.并利用矩量法,对具体天线的电流分布进行了数值计算,给出了该天线在选取不同加载参数时的电流幅度与相位分布曲线.结果表明:天线在最佳加载时,可以得到较好妤的行波电流分布特性.

This paper discusses the radiation properties of the disc reflector ofmonopole antenna fed by the conductor of coaxial cable under the conditionof hyperbola loading.The numercial solution of the antenna currentdistributions is calculated with the moment method,whereby the currentamplitude and phase distributions on the antenna corresponding to differentloaded parameters are presented.The results indicate that under anoptimum loading condition,the current distributions corresponding to abest traveling wave be obtained.
