柴比契夫或準橢圓函數之準八分之一波長諧振腔濾波器

Abstract

一般而言，在微波及毫米波濾波器中，梳形及交錯柵形濾波器應是體積最小的濾波器，在本論文中運用平面式之電路結構及介電係數較低的材料，且採用較為簡單不費時的設計方法製作微型化帶通濾波器。 文中將介紹柴比契夫或準橢圓函數之準八分之一波長諧振腔濾波器，並實際製作雛形電路驗證設計流程的可行性及理論的正確性。

In general, the combline and interdigital filter are two of the smallest size in those of microwave and millimeter wave filters. In this thesis ,miniature bandpass filters with planar structure and low dielectric constant subtrate are constructed by using a simple and time-saving method. Quasi-1/8 wavelength resonator filters with Chebyshev or quasi-elliptical function response are designed and fabricated to verify the accuracy and reliability of synthesis theor
