摘　　要：根据阶跃阻抗谐振器(SIR)的基本原理,采用λg/4型SIR作为单位元件谐振器,组成交叉耦合多级同轴带通滤波器。在结构中引入以零相位方式接入的抽头,并通过HFSS仿真进行了优化。实验结果表明,其尺寸比例比常用的梳状线滤波器形式显著减小,很好地实现了滤波器的小型化设计。According to the basic principle of stepped impedance resonator （SIR）, λg/4 -type SIRs are adopted as elements to compose cross - coupling multilevel coaxial bandpass filter（BPF）. Tapped line with the zero -phase mode to connect is adopted in the configuration and has been optimized by utilizing EM emulator. Finally, the experiment result shows that its proportion of size is obviously reduced, relative to the usual combline filters, and the miniaturization design of the filter is realized.
