| 摘 要： | 摘要： 在超宽带天线设计中采用一种快速有效的优化方法. 该方法将改进的量子遗传算法与基于矩量法的体面积分方程相结合，利用最佳一致逼近快速分析天线的宽频带特性，得到优化函数的适应度值. 用该方法设计一副具有3?4 GHz和5?6 GHz双阻带特性的UWB天线并制成实物，将实测电压驻波比与优化结果进行比较，两者较为吻合，说明该方法是正确的、有效的.

| Abstract: | To design ultra-wideband antennas,an efficient method is used.The method combines an improved quantum genetic algorithm(IQGA) and the volume surface integral equation based on the method of moment. Computation time is saved by using optimum uniform approximation that accelerates the analysis of the ultrawideband antenna's characteristics in calculating fitness.A novel microstrip-fed UWB antenna with dual notch bands in 3~4 GHz and 5~6 GHz is designed and fabricated.Comparison between the optimized and measu... |
