| 摘 要： | 针对三维全波仿真提取微波谐振腔耦合系数耗时长和提取结果不易被收敛的问题,提出了一种基于等效电路Y参数的耦合系数提取方法,并将该方法应用到改进的渐进空间映射算法的参数提取过程中,提高了滤波器的设计效率。通过一个4腔同轴腔体滤波器的设计实例进行了验证,滤波器的电磁仿真结果与理论综合结果吻合良好,证实了该方法的有效性。

| Abstract: | The 3D full wave simulation of filters for coupling coefficient extraction is time-consuming and it is difficult to converge the extraction result. A method for extracting coupling coefficient based on the Y parameter of equivalent circuit is proposed and used in the extraction of the aggressive space mapping algorithm to improve the efficiency of filter design. A design example of a 4 cavity coaxial cavity filter is provided. Simulation results are in good agreement with the theory of electromagnetic filter synthesis results,confirming the validity of the proposed method. |
