摘　　要：等离子体具有优异的导电性能,利用等离子体作为电磁能量传导介质的等离子天线相比于普通的金属天线,具有隐身性好、体积更小、重量更轻、可动态重构等特性。采用MATLAB数值仿真模拟研究了天线的辐射场问题。结果表明:随着天线长度、密度等参数的不同,其电流分布图、辐射方向图都会发生相应的变化,也就是说其辐射方向具有可控性。Plasma has excellent electric conductivity. Compared to ordinary metal antenna, plasma antenna which uses Plasma as an electromagneticenergy conductive medium, has greater stealth, smaller volume, lighter weight, and dynamically refactoring features. Therefore, study of plasma antenna is of great significance. This paper uses the numerical simulation based on MATLAB to study the antenna radiation field problem. As is shownin the re- suits： thecurrent distribution map and radiationpattern will ehangeaccordingly with the changes of antenna length, density and other parameters. That is to say, the radiation direction is controllable.
