摘要

为了实现组合滤波器的小型化，提出了一种新型谐振腔。所提出的谐振器类似于螺旋谐振器。为了验证该谐振器的有效性，设计了一个中心频率为160MHz、相对带宽为50%的通带滤波器。仿真结果表明，与传统的电容负载m型结构组合滤波器相比，该滤波器的尺寸减小了25%。

Design of a novel compact combline filter

This paper proposes a novel resonator to achieve miniaturization of combline filter. The proposed resonator is similar to helical resonator. To demonstrate the validity of the proposed resonator, a pass-band filter with a center frequency of 160MHz and a relative bandwidth of 50% is presented. Simulation results show that this new design can reduce the dimensions by 25% compared with the conventional combline filter with M-shaped structure of capacitance-loaded.
