本論文主要分為兩個部分，第一部分將介紹小型化帶通濾波器，首先初始架構採用加入殘段的雙端短路諧振腔(Stub Loaded Short-Ended Resonator)，而後再將兩迴路型諧振腔以耦合線方式對接產生通帶，最後再利用四分之一波長的短路殘段抑制倍頻，進而完成帶通濾波器之設計。
而在第二部分將介紹寬頻帶拒濾波器之設計，首先利用柴氏低通雛型濾波器所衍生的公式推導而得帶拒雛型濾波器為原型，再以改變串聯傳輸線段改善頻帶外極點位置，而後則改變並聯之短路殘段電氣長度，此舉能夠改變頻帶內零點位置，進而達到寬頻特性，最後則將改變電氣長度後的並聯殘段以步階阻抗(Stepped-Impedance)傳輸線取代，藉由調整步階阻抗傳輸線的阻抗比例能夠調控頻帶兩端零點位置，增加頻寬設計自由度。
