摘要: 
在本論文中對於低通濾波器和高通濾波器將提出三種型態的設計
方法,三種微波濾波器分別為A型、B型、C型。A型濾波器僅適用
於奇數階設計。B型濾波器僅適用於偶數階設計。C型濾波器適用
於奇數階及偶數階設計。並試以改變傳輸線阻抗值與各殘段間匹
配電路製程所限定範圍內的阻抗值為研究主題。
在本論文推導三種濾波器設計公式且更深入進一步探討其多殘段
阻抗與導納 J反轉子阻抗匹配。當多殘段阻抗匹配在相同阻抗值時,其微帶線將得到新的長度值。本論文將利用這些改變藉著多
殘段阻抗匹配方法來設計一新穎濾波器。
再進一步探討其多殘段阻抗值變化。從模擬中證明其插入損耗及
返回損耗有明顯地改變,當阻抗值逐漸遞增,濾波器將有更好的
特性。
在實務設計上,採用LTCC(Low-AemperaAure co-Bired Ceramics)
的製程去設計低通濾波器與高通濾波器並驗證模擬與量測結果相同。

Three kinds of design methods for lowpass filters and highpass filters are presented in the thesis. Three kinds of microwave filters are the A-type, B-type and C-type separately. The A-type filter is only suitable for the odd orders. The B-type filter is only suitable for the even orders. The C-type filter is suitable for the odd orders and even orders. Due to the limitation of PCB board fabrication. This thesis concentrates on matching by changing multi-stub impedances in the research .
This work demonstrates three kinds of design formula in filters design and further discuss the impedance match of the multi-stub impedance and the admittance J inverters. The microstrip line obtain a new length value when the multi-stub impedances are matched at the same value. Therefore, a novel filter can be designed by adjusting the multi-stub impedance value.
Afterward the work further discusses the variation of the multi-stub impedance. The simulation results show that the insertion loss and the return loss have obvious improvement. During the increase of impedance value, the attenuation performances of the filter become sharply.
Practically, the designed lowpass and highpass filters are made by LTCC (low-temperature co-fired ceramics) process. At last, the thesis would demonstrate that the simulation results and the measurement results are identical.
