摘要
根据实际使用要求,运用遗传算法设计天线宽带匹配网络,同时兼顾了带宽和效率。设计过程中对目标函数以及适应度函数的选取进行了讨论,并结合射频仿真软件ADS,仿真分析了宽带匹配网络。设计结果表明,天线在带宽范围内端口驻波比小于1.6(V SW R<1.6)同时效率达到了35%以上,证明了遗传算法是一种有效的设计匹配网络方法。
The design of broadband matching network of antennas based on Genetic Algorithm (GA) is discussed in this paper. Bandwidth and efficiency for practical application have been taken into consideration in the design. How to choose Object function and Fitness function has also been discussed. Simulation and analysis of the design has been done with radio frequency software ADS. Result shows that in the bandwidth range antenna with VSWR is less than 1.6 while the efficiency reaches above 30% and thus has proved that genetic algorithm is an effective method for designing matching network.
