摘　　要：基于矩量法理论，采用遗传算法对宽带集中加载单极天线进行了优化设计。根据优化的结果设计了一付天线，在30～540MHz频率内VSWR〈3．5，阻抗带宽达到18：1，天线高度为1．6m，适用于移动的载体多频段通信系统。实验结果表明，该方法是有效的和可行的。Based on method of moments （MOM）, a broadband loaded wire monopole is designed, and the loads of parallel inductor/resistor circuits are optimized by means of genetic algorithms （GA）. As a designed result, a antenna used for mobile and muti-frequency bands communication system is fabricated. The tested results show that the antenna is of banwidth ratios of 18.1 with measured VSWR less than 3.5 and a height of 1.6 meter.
