摘　　要：该文针对目前频率可重构微带天线的优化设计常依赖于反复实验的现状,提出了一种快速有效的频率可重构微带天线优化设计方法,该方法将新型量子遗传算法与通用的空域矩量法结合,在计算阻抗矩阵时利用了直接矩阵操作技术,大大节约了计算时间。利用该方法,优化出一副可工作在十个甚至更多的窄频段的变频圆柱共形可重构微带天线,优化结果与相关软件结果的比较显示了该文方法的正确性及高效性。For changing the status that optimization and design of frequency reconfigurable microstrip antenna recently is usually depended on repeated experiments,an efficient and fast method is proposed in this paper.A Novel Quantum Genetic Algorithm（NQGA） is combined with universal spatial MoM in the proposed method and calculating time is saved by using Direct Matrix Manipulation（DMM） technique used in computing Z-matrix.Using this method,a frequency reconfigurable cylindrical conformal microstrip antenna is obtained that can work at ten or more narrow frequency-bands.Comparing the optimization results in the paper with commercial software results shows that the method in this paper is correct and efficient.
