摘要
短波天线作为高频电流和空间电磁波之间能量转换的核心部件,其辐射场直接影响通信系统的整体工作性能。论文详细分析RWG矩量法数值计算短波天线辐射场的基本原理,以近地短波鞭状天线为例,建立仿真模型,进行了阻抗和场强方向图的仿真,所得仿真结果与商用软件FEKO的仿真结果进行对比,二者吻合较好。
Shortwave antenna is used as a core component for energy conversion between the high-frequency current energy and free-space electromagnetic wave and its radiation field will directly affect the overall performance of the communication system.This paper researches the basic principle of RWG-MoM used for numerical simulation and calculation of shortwave antenna radiation field is analyzed in detail,the impedance and field patterns of short-wave whip antenna is simulated and the results reach a good agreement with commercial software FEKO.
