摘要

本文研究了一种基于衬底集成波导的四模滤波器。该滤波器的基本元件是一个三分之一三角形谐振器，具有两个电壁和两个虚磁壁。该谐振器称为三分之一模衬底集成谐振器(OTMSIR)。为了设计四模滤波器，研究了OTMSIR中存在的不同模式的电场分布和频率。选用椭圆金属通孔实现滤波。探测到的地面结构(DGS)用于抑制其他高阶模态。最后，完成了13GHz带宽平面四模滤波器的设计。

Investigation of planar wide band quadruple-mode filter based on substrate integrated waveguide

In this paper, a quadruple-mode filter based on the substrate integrated waveguide (SIW) is investigated. The basic element of the filter is a one-third triangular resonator with two electric walls and two virtual magnetic walls. The resonator is called one-third-mode substrate integrated resonator (OTMSIR). The electric field distribution and frequencies of different modes existed in the OTMSIR are studied in order to design a quadruple-mode filter. An elliptical metallic via-hole is selected to realize the filter. A detected ground structure (DGS) is used to restrain other higher-ordered modes. Finally, the design of a 13GHz bandwidth planar quadruple-mode filter is fulfilled.
