本文利用对比法和仿真法介绍了一种采用简单圆柱谐振器的四模介质谐振器滤波器,以实现不同的、高效的滤波功能。在四模谐振器的基础上,设计、仿真并制作了四极单腔滤波器。此外,还介绍了一种新型双模介质谐振器滤波器,该滤波器采用沿其轴线切成两半的同一圆柱谐振器。与传统的介质谐振器滤波器相比,本文提出的介质谐振器滤波器明显改良尺寸和提升质量,在无线和卫星应用方面有广泛的前景。

In this paper,a four-mode dielectric resonator filter with a simple cylindrical resonator is introduced by contrast method and simulation method to achieve different and efficient filtering functions.Based on the four-mode resonator,a quadrupole single-cavity filter is designed,simulated and fabricated.In addition,a new type of two-mode dielectric resonator filter is introduced,which USES the same cylindrical resonator cut in half along its axis.Compared with the traditional dielectric resonator filter,the dielectric resonator filter presented in this paper has improved size and quality significantly,and has a broad prospect in wireless and satellite applications.
