摘　　要：为了平衡天线设计的精度与速度之间的矛盾,提出了一种演化算法结合正交测试的天线设计方法.首先基于自适应参数调整差分演化(jDE)算法设计了一种改进jDE(i-jDE)算法,在保证优化效果的同时尽可能减少仿真次数,并与快速电磁仿真软件结合得到初步的天线设计.以此为初始方案,采用分布式正交试验方法与高精度电磁仿真软件结合,进一步改进设计.实验结果表明该方法能更快更好地优化天线结构.To balance the contradictory between accuracy and speed of antenna design ,an antenna de‐sign method through evolutionary algorithm combined with orthogonal test was proposed .An im‐proved jDE （differential evolutionary） algorithm i‐jDE was proposed first to ensure the optimal effect with fewer simulation times ,and that a preliminary antenna design could be obtained using the algo‐rithm with the fast electromagnetic simulation software .Then the design was further improved by means of distributed orthogonal test method with the high precision simulation .The experiment re‐sults demonstrate that with the method the structure of antenna can be designed faster and better .
