摘要
本论文将遗传算法成功地应用到微带天线的优化中 .论文中详细讨论微带天线采用遗传算法进行优化的一些基本问题 ,如基因串的定义 ,遗传算法与矩量法的结合 ,适应度函数的设计以及控制参数的选择等 .最后 ,论文成功地应用遗传算法 ,优化出宽带天线 ,带宽由初始 5 %展宽到 16 6 % ;并优化出双频工作天线 ,双频比为 1∶1 31,而且具有同向的线极化 .
Genetic algorithms (GAs) are successfully applied to the optimization of microstrip antenna design.This paper discusses some basic problems in this application thoroughly,such as the definition of genetic series,the combination of GAs and method of moment,the design of fitness function and the selection of control parameters.Using GAs,a wide band microstrip antenna is designed,the bandwidth expands from 5% to 16 6%.A dual frequency antenna is also optimized.The ratio of these two frequencies is 1∶1 31 and both frequencies have the same linear polarization.
