一种基于IQGA的UWB陷波天线的设计

内容简介：给出了一种改进的量子遗传算法（IQGA）,克服了其易陷入局部极值的缺点,再将其与基于矩量法的体面积分方程和最佳一致逼近结合,加速了超宽带天线的特性分析,设计优化了一副采用微带线馈电的超宽带陷波天线。该天线在3.1～10.6GHz频带范围内反射系数低于-10dB,而在5.8GHz的窄带范围内具有反射系数高于-10dB的陷波特性。最后制作出了该副天线,优化结果与实测结果的比较反映了该方法的正确和有效性。

Abstract：In this paper,an improved quantum genetic algorithm（IQGA） is used to design and optimize a microstrip-fed ultra-wideband antenna with band-notched characteristic in conjunction with the best uniform approximation and volume surface integral equation based on the method of moment which accelerates the analysis of the ultra-wideband antenna′s characteristic.The antenna′s reflection coefficient is lower than-10dB in the band from 3.1GHz to 10.6GHz except a narrow band around 5.8GHz.An experimental antenna is produced.The measured results show that the method is correct and effective.
