本論文強調使用二分之一波長與四分之一波長共振器組合來設計四階帶通濾波器。 在第一種架構中，三段四分之一波長的共振器和一個二分之一波長的共振器用來實現一種新的帶通濾波器，為了得到一對額外的傳輸零點，可改變在二分之一波長共振器的饋入位置，以達到設計需求。
在第二種類型的濾波器中，使用二分之一波長和分支線的共振器，且提出了兩個新的微帶線帶通濾波器，第一個架構的濾波器是使用非零度饋入結構的輸入和輸出共振器來讓通帶旁產生出一對傳輸零點。為了達到良好的選擇性，且提高阻帶抑制，在第二個架構的濾波器所利用零度饋入結構，以滿足所需要的響應。最後實際量測和電磁模擬結果都有良好的一致性。

This dissertation emphasizes four bandpass filter designs using the combination of half-wavelength and quarter-wavelength resonators.
In the first case, three quarter-wavelength resonators and one half-wavelength resonator are utilized to realize a new type of bandpass filter. To obtain one additional transmission zero, the feeding location of the half-wavelength resonator may be modified to achieve the requirement.
In the second type of filter, two new microstrip bandpass filters using half-wavelength and branch-line resonators are also proposed. The first case of this type filters is used a non-00 feed structure at the input and output resonators to create one pair of transmission zeros around the passband. To achieve good selectivity and improve stopband rejection, the second case of this type filters is utilized a 00 feed structure to meet the required responses.
Specifically, the measured and simulated results are in good agreement for all the filters in this dissertation.
