摘要
在对天线进行优化设计时,直接使用HFSS等仿真软件进行参数扫描往往需要大量的时间。为解决这一问题,将代理模型法与差分进化(DE)算法相结合,减少了优化过程中的精确电磁仿真次数,显著减少了优化所需时间。随后,使用该方法优化设计了一个准八木天线,结果表明,在10~11GHz频段内,天线反射系数小于-27dB,验证了算法的有效性。
During the optimization design of antennas,directly using simulation softwares such as HFSS,etc.to perform parameter scan may cost a lot of time.In order to solve this problem,this paper combines surrogate model with differential evolution(DE)algorithm,which reduces the times of exact electromagnetic simulation in optimization process so that the optimization time is significantly reduced,then designs a Quasi-Yagi antenna by using this method,the result shows that the antenna reflection coefficient is less than-27 dB within the frequency band of 10~11GHz,which validates the effectiveness of the algorithm.
