本文主要提出三種新型傳輸零點架構，分別對各個傳輸零點架構做數學推導及架構分析，展示其數學模型上的限制及製程上的實作極限，且利用短路型馬蹄耦合線結合本文的新型傳輸零點架構來設計微波帶通濾波器，使帶通濾波器在通帶外的選擇性更佳，使電路更不容易受其他雜訊干擾。
經由短路馬蹄耦合線設計的帶通濾波器架構下，相比以往傳統濾波器設計頻寬限制大幅提升，實現了電路在中頻寬實作上的限制，利用本文所提出的新型傳輸零點架構結合濾波器，分別以頻寬30%、40%、50%規格進行模擬與實作，最終電路所呈現的帶外選擇性非常良好。
透過本文所提出得三種新傳輸零點架構及短路馬蹄耦合線設計濾波器的流程下，能滿足不同頻寬的電路需求及實現於各種PCB電路板上，達到易設計、成本低廉，且本文有一套完整的數學公式。

This paper mainly proposes three new transmission zeros architectures, which respectively perform mathematical derivation and architecture analysis on each transmission zeros architecture, show the limits of the mathematical model and the implementation limits on the process, and use the Spur lines to combine the new transmission zeros of this paper. The architecture is designed for microwave bandpass filter that makes the bandpass filter more selective outside the passband, and reduce noise interference on the circuit.
Under the band-pass filter architecture designed by the Spur lines, the bandwidth limit of the filter design is better than previous ones, and the limitation of the circuit in the implementation of the medium bandwidth is realized.
The filters are simulated and implemented in 30%, 40%, and 50% bandwidths respectively. The out-of-band selectivity of the final circuit is very good.
Through the flow of three new transmission zeros, architecture and Spur Line design are proposed in this paper, it can meet the circuit requirements of different bandwidths and realize on various PCB circuit boards, which is easy to design and low in cost, and this paper has a set. Complete mathematical formula.
