摘要
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。
The original value calculated with existing method for designing microstrip combline filter has big error and is difficult to optimize.To resolve this problem,a new method to design microstrip combline filter was proposed based on comparison between stripline model and microstrip line model.The basic idea behind this method was to design microstrip combline filter by changing models based on stripline combline filter design method.Calculation in this method was simple,and the original value was accurate.The new method was validated by ADS simulation results.
