提出了一种基于遗传算法的微带三带通滤波器设计方法。VGA的应用，同时寻找合适的电路拓扑结构和相应的电参数与三频特性。为了证明VGA的有效性，一个三频BPF的设计和制造。在滤波器中，中心在2.05，3.57和5.81 GHz的三个通带的3 dB分数带宽分别为14.63，11.20和7.57%。测量结果与设计指标和全波电磁仿真结果吻合较好。
A new microstrip triple-band bandpass filter (BPF) using a variation of genetic algorithm (VGA) is proposed in this paper. The VGA is applied to simultaneously search for the appropriate circuit topology and the corresponding electrical parameters with a triple-band characteristic. To demonstrate the effectiveness of the VGA, a triple-band BPF is designed and fabricated. In the filter, the 3 dB fractional bandwidths for the three passbands centered at 2.05, 3.57, and 5.81 GHz are 14.63, 11.20, and 7.57%, respectively. Measurement results agree well with the design index and full-wave EM simulated results.
