| 摘 要： | 从滤波器的工作原理出发，分析了梳状线带通滤波器的结构特征，推导了抽头式输入输出结构的网络表达式，并对其进行简化等效，得到了与传统设计中使用的变换器输入输出相等效的表达式，用高频结构仿真软件HFSS进行了仿真，并通过实例设计，验证了此方法的有效性．

| Abstract: | Based on the principle of filters, the structural characteristics of comb line were analyzed, and the formulas of tapped line input and output filter were developed. By using the new equivalent circuit, the explicit expressions were given for all parameters of the circuit. The expressions correspond to those in traditional design in which the transform was used as input and output. The simulation results of the high frequency structure simulation HFSS platform verified the approximation. According to the design, it was shown that this method is valid. |
