阶梯阻抗变换器的遗传算法优化设计

Optimization design for the stepped impedance transformer based on the genetic algorithm

介绍了阶梯阻抗变换器的基本原理及其数学模型,重点讨论了阶梯阻抗变换器两种设计方法间的优劣,用电子设计自动化(EDA)软件对设计结果进行了仿真,仿真结果表明:就最大反射系数模值的指标来说,遗传算法设计结果普遍优于Chebyshev综合设计结果。

This paper introduces the basic principium and mathematic model of the stepped impedance transformer, then puts the emphasis on comparing two kinds of design methods of the stepped impedance transformer. The design results are simulated by EDA, which indicates that genetic algorithm design is better than Chebyshev integrated design in the term of the most reflect coefficienfs module.
