摘　　要：为了满足实际电子对抗领域的需求,在有限空间内设计了一个UHF频段的双频单极子天线,并使用数值软件中编写的遗传算法(Genetic Algorithm,GA)联合电磁仿真软件仿真的方式,设计并优化了匹配电路,使得天线在保留原有增益的情况下显著地提升了带宽。使用算法优化后的天线在135〜175MHz,270〜300MHz驻波比小于2.5,带宽是优化前的3倍,增益能满足使用要求。In order to meet the requirements ofthe real electronic countermeasures,an UHF dual-band monopole antenna is designed in the limited space,and the matching circuit is designed and optimized by Genetic Algorithm(GA)in Matlab combined with ADS and CST simulation,so that the antenna can significantly improve the bandwidth while retaining the original gain.The simulation results show that the antenna completely covers the bands from 135 MHz to 175 MHz and also from 270 MHz to 300 MHz with the VSWR lower than 2.5,and the bandwidth is increased by three times,making the gain meet the requirements.
