随着短背射天线在民用通信方面的广泛应用,以往的分析、计算因方法粗略,越来越不能胜任要求.本文采用栅网模型去模拟实用短背射天线,应用矩量法分析、计算了有边环短背射天线的电流分布及由此求得的远场方向图、输入阻抗等.对于短背射天线的设计计算是很有用的.
With the wide application of short back-shot antenna in civil communication, the past analysis and calculation are rough and can not meet the requirements more and more.This paper uses grid model to simulate practical short back-projection antenna, The current distribution of the edge-ring short back-projection antenna and the far-field pattern, the input impedance and so on obtained from it are very useful for the design and calculation of the short back-projection antenna.
