摘　　要：基于微带贴片天线的空腔模型理论,在大量仿真和实验数据的基础上,给出了蝶形天线谐振频率的经验式.该式与以前的计算式相比,具有更高的精度,能满足工程应用的需要.以该式为适应度函数,研究了采用二进制编码的简单遗传算法设计蝶形微带天线贴片尺寸的方法.设计结果和实验结果比较表明,所用设计方法是有效和可行的.A modified empirical resonant frequency of bow-tie microstrip antenna was given, which is based on the cavity model of microstrip antenna. The simulation and experimental data verify the accuracy of the formula. A process to design bow-tie microstrip antenna in which the formula is taken as a fitness function was presented. An optimized bow-tie antenna by the genetic algorithm was constructed and measured. The result demonstrates the validity and efficiency of the genetic algorithm.
