摘要

本文提出了一种基于自封装频率相关耦合（SPFDC）结构的高选择性基板集成波导（SIW）带通滤波器，该滤波器由耦合窗口和带金属化盲孔的嵌入式带状线组成。所提出的SPFDC具有可控制的耦合系数斜率、传输零点位置和耦合强度。为了验证所提出的SPFDC，设计、制作并测量了基于三个SPFDC的内联四阶SIW滤波器和基于一个SPFDC的交叉耦合四重SIW滤波器。实现了具有三个有限传输零点的高选择性响应。

Substrate-Integrated Waveguide Filters Based on Self-Packaged Frequency-Dependent Coupling Structure

Highly selective substrate-integrated waveguide (SIW) bandpass filters based on a novel self-packaged frequency-dependent coupling (SPFDC) structure is presented in this letter, which is composed of a coupling window and an embedded stripline with a metallized blind hole. The proposed SPFDC exhibits controllable slopes of the coupling coefficients, positions of the transmission zeros and coupling strength. To demonstrate the proposed SPFDC, an inline fourth-order SIW filter based on three SPFDCs and a cross-coupling quadruplet SIW filter based on one SPFDC have been designed, fabricated and measured. Highly selective responses with three finite transmission zeros are realized.
