U頻段及V頻段濾波器之設計

Abstract

本論文在Rogers Duroid RO3850以及Rogers Duroid RO5880兩種板材之下，設計並研製40~48GHz的平行耦合微帶線帶通濾波器，以及59~62GHz的耦合共振帶通濾波器，最後並對照兩種板材下的設計結果。 另外為了高頻系統的應用，在本論文亦設計濾波器的金屬外殼封裝，除了說明完整的設計的流程之外，並提出在組裝過程中所改良的步驟及最後結果。

The main objectives of this thesis are to use the two kinds of subtrates (Rogers Duroid Ro3850 and Rogers Duroid Ro5880) to design the 40~48GHz coupled-line filters and the 59~62GHz coupled-resonator filters. Specifically, the results for these two subtrates under same specification are carefully examined and compared . In order to apply to the high frequency system, not only the complete design process of the housing of filter, but also the improvements and the measurement results are presented in this thesis.
