摘　　要：应用矩量法计算了折线电天线、方形环天线和加载电容方形环天线的电流分布,计算结果表明:当加载电容的方形环天线所加载的电容很大或很小时,其电流分布分别与闭合环天线和开路折线电天线的电流分布相吻合;并在此基础上进一步计算和分析了不同频率下环路闭合与开路的天线辐射场,研究结果对分析电磁兼容共模辐射问题有一定的参考价值。The current distribution of a folded antenna, a quadrate loop antenna and a loop antenna with load capacitance is analyzed by using MoM. It is shown from the simulation results that wthen the capacitance is very large or small, the current distribution of load antenna is same as that of quadrate loop antenna and folded antenna. Finally, the radiation fields of short circuit and open circuit loop antenna operated at different frequencies is provided.
