针对现有微带线梳状滤波器设计方法在计算滤波器初始值方面存在误差较大、优化困难等问题,通过带状线模型与微带线模型的比较,提出一种新的微带线结构梳状滤波器设计方法。该方法基本思路仍然采用带状线梳状滤波器的设计方法,通过简单的模型变换,即可设计相应的微带线梳状滤波器。该设计方法计算简单,初始值计算较为精确。利用ADS软件对设计初始值进行仿真比较,证明了该设计方法的有效性。 In order to solve the problem that the design method of the existing microstrip line comb filter has large error and difficult optimization in calculating the initial value of the filter, a new microstrip line is proposed by comparing the strip line model and the microstrip line model Structure comb filter design method. The basic idea of ​​this method still adopts the design method of the strip line comb filter. By simple model transformation, the corresponding microstrip line comb filter can be designed. The design method is simple to calculate, and the initial value calculation is more accurate. Using ADS software to simulate the initial design value, the validity of the design method is proved.
