摘要：

运用遗传算法研究一种超宽带微带对数周期天线，程序中采用了低电压驻波比和高增益多目标函数. 对比分析了遗传优化结果和传统方法设计结果，制作了实物天线并进行测试，获得了很好的结果. 所设计的天线能以较好的电特性和场特性工作在L和S两个波段，验证了遗传算法在此类型超宽带天线设计中的有效性.

Abstract:

An ultra-wideband microstrip log-periodic antenna (UWB-MLPA) is studied by using genetic algorithms (GA). A multi-object function with low VSWR and high gain is used in the program. The results of GA optimization are compared with traditional methods. An antenna is designed and fabricated, and outdoor measurements carried
out with good results. The antenna can operate in the L/S band with good electrical and radiation characteristics.
It is shown that GA is an effective method for this type of UWB antennas.

Key words: genetic algorithm, ultra-wideband, microstrip log-periodic antenna, multi-object function
