Abstract

This article presents a new method for substrate integrated waveguide (SIW) filters to achieve wide stopbands. Using the proposed staggered inter-coupling structures, double-layer SIW filters working at the fundamental mode TE101(f0) can have wide stopbands up to TE10(2n-1), where $n$ is the order of the filter. They can break the upper limit of the stopband extension and have coplanar ports suitable for planar circuits and systems in comparison to their multilayer counterparts, and they can further extend the stopbands and have shielding structures suitable for high-performance and high-frequency applications compared to their hybrid counterparts. Three examples are provided. The measured results show that they respectively achieve wide stopbands up to 3.97f0, 5.22f0, and 6.53f0. The proposed technique should be effective for developing wide stopband SIW filters for microwave circuits and systems.

TE101基片集成波导滤波器，宽阻带高达TE10（2n- 1）和共面端口

本文提出了一种衬底集成波导（SIW）滤波器实现宽阻带的新方法。使用所提出的交错耦合结构，工作在基模TE101（f0）的双层SIW滤波器可以具有高达TE10（2n-1）的宽阻带，其中$n$是滤波器的阶数。与多层材料相比，它们可以突破阻带扩展的上限，具有适合平面电路和系统的共面端口，并且与混合材料相比，它们可以进一步扩展阻带并具有适合高性能和高频应用的屏蔽结构。提供了三个示例。实测结果表明，它们分别实现了3.97f0、5.22f0和6.53f0的宽阻带。该技术对于开发用于微波电路和系统的宽阻带SIW滤波器是有效的。
