摘要
用级联法设计全等宽耦合微带线带通滤波器时,要多次对参量进行调整、验证,尺度不好把握,难以得到最佳值。针对此问题,将改进的遗传算法与级联法结合使用,不需对参量反复调整,这不仅节省了设计时间,且能一次得到最佳参量值。通过例子证明此方法是有效的。
In designing the Band-pass filter of parallel coupled microstrip lines with egual width by using cascade methed,some parameters should be adjusted many times and the results should be validated repeatedly thus causing some difficulties in determining the optimum parametersTo counter this problem,the combination of an improved genetic algorithms and the cascade method is presented in this paperThe optimal parameters can be obtained,by using the combinative method,through single computation and without adjustmentsAt last the validity of the method is verified through an example
