基片集成波导滤波器高性能化研究

As a novel guide wave technology with distinctive advantages, substrate integrated waveguide (SIW) has been well developed and widely used since the past decade. Hundreds of papers have been published to demonstrate the novel properties and capacities of SIW applications, of course, including SIW filter. Nevertheless, unfortunately, the performance of current SIW filter is not that perfect because of some born and hard to be overcome limitations of SIW. In this project, the limitations will be bypassed; the performance of SIW filter will be improved by investigating fundamental mode and dual mode co-design technology. This project also investigates balanced SIW filter, based on the own advantages of SIW, combining hybrid substrate integrated technology, and applying fundamental mode and dual mode co-design technology just proposed, the balanced SIW filter will acquire much more flexible design, compact size, and well balanced performance. The successful completion of this project supposes to make SIW filter become a competitive candidate for the development of modern microwave/millimeter-wave circuits and systems.

基片集成波导（Substrate Integrated Waveguide, SIW）是一种特点鲜明的新型微波毫米波导波技术，一经提出便得到了迅速发展与广泛应用。滤波器作为微波毫米波电路的重要组成部分，是SIW的重要应用场合，但由于结构上的限制，SIW滤波器还存在诸多不足。本项目拟通过研究主模&双模在SIW滤波器设计中的协同关系以及相互作用，绕开SIW结构上的限制，探索新的设计方法，实现SIW滤波器的高性能化。本项目还拟研究SIW在平衡滤波器中的应用，基于SIW自身优点，结合混合基片集成技术，并延续主模&双模协同设计，使得SIW平衡滤波器获得更灵活的设计、更小的电路面积以及更好的平衡性能。本项目将使得SIW滤波器更加适合现代微波毫米波电路系统并为其发展增添一点动力。
