Ka波段基片集成波导带通滤波器的设计

内容简介：基片集成波导（SIW）是近年发展起来的一种新型微波传输结构。应用基片集成波导技术，通过实现耦合腔间的正负耦合，设计了应用于毫米波的交叉耦合滤波器。经三维电磁仿真，通带回波损耗大于22dB，最小插入损耗小于1．5dB。仿真结果表明该滤波器具有极高的实际应用价值。

Abstract：Substrate integrated waveguide （SIW） is developed in recent years as a new structure for microwave transmission. In this paper, by realizing the positive and negative coupling between two coupled cavities, a cross-coupled filter for millimeter wave application is designed based on SIW technology. The Simulation results confirmed the reflection of pass-band lower than 22 dB and insertion loss better than 1.5 dB.
