摘要
为同时兼顾带宽和效率,将遗传算法应用到天线宽带匹配网络设计中。遗传算法中建立了多目标优化目标函数即适应度函数。根据算法寻优结果,结合仿真软件仿真分析了所设计的宽带匹配网络的电特性。结果表明:该宽带匹配网络具有良好的阻抗宽带性能,证明了遗传算法在设计宽带匹配网络中的有效性。
Concerning about the bandwidth and efficiency, genetic algorithm was used to design the broadband matching network of antennas, and a multi-objective optimization objective function, namely fitness function, was established in genetic algorithm. According to the result of genetic algorithm, the electricity characteristic of the design was simulated with simulation software. Simulation result shows that the broadband matching network has good electronic capability and the genetic algorithm is effective in broadband matching network.
