摘要

本論文的研究重點為如何設計微波濾波器，並且加以實現，就濾波器的各個參數加以討論，其中將以等效電路的觀點切入，對濾波器設計進行詳細的分析與探討，利用參數萃取從結果得到共振腔間的耦合係數及輸入輸出阻抗，以便於濾波器結構的微調。最後將提出新的濾波器設計概念，並利用理論與模擬證明實做的可能性。

The main topic of this thesis is how to design and implement the microwave filters. And we will go to discuss the frequency response effect of the dimensions about the filters. By using the opinion of ideal circuits’ model, we analyzed and discussed the design of filters in detail. To extracted coupling coefficients and input/output resistance from the results, in order to facilitate to fine-tuning of the filter structure. Finally, we proposed a new concept of filter design, and use the theory and simulation to prove the possibility of implementation.
