通过实例的形式,讲述了微带带通滤波的一般结构,并利用新型的先进设计系统2009(ADS2009)进行了微带带通滤波器的设计,并进行了仿真,由于仿真结果的不理想,利用先进设计系统(ADS,Advanced Design System)的优化工具对各个参数进行优化,在优化的过程中针对以前ADS优化重复次数多,耗时间长的问题,着重讲述了利用ADS2009快速简便的优化结果的方法——多层优化,取代了以前繁琐的优化方法,并给出了优化前后的对比,明显优化了结果,可以证明该种优化方法的可行性。
The general structure of the microstrip bandpass filter is described through an example, and the design of the microstrip bandpass filter is carried out by the new advanced design system 2009 (ADS2009). The simulation results show that the simulation results are not satisfactory, Using the optimization tool of Advanced Design System (ADS), each parameter is optimized. In the process of optimization, ADS2009 is optimized to optimize the number of repetitions and time-consuming problems, and focuses on the quick and easy optimization of results using ADS2009 The method - multi-layer optimization, replaces the previous cumbersome optimization method, and gives the comparison before and after optimization, and optimizes the result obviously, which proves the feasibility of the optimization method.
