摘　　要：提出了一种用遗传算法和HFSS优化设计超宽带陷波天线的方法.在该方法中,反射系数的适应度函数被作为目标函数,在确定结构的前提上对天线的参数进行优化.根据遗传算法的优化结果设计出一款新型UWB陷波天线,并采用仿真软件对天线的电特性进行了仿真,从而证明该方法有效.A method to optimize and design ultra wideband(UWB) antenna with notched-band based on genetic algorithm(GA) and HFSS is presented in this paper. The value of reflection coefficient is used to be the objected function. Genetic operation is applied to the optimization of antenna structure dimensions based on determining the structure. A UWB antenna with notched-band is designed using the results of optimization by GA and its electrical properties such as the return loss is simulated with HFSS(high frequency simulation software). It has been proved that GA is an effective method for designing UWB antenna.
