| Summary: | 碩士 === 國立交通大學 === 電信工程系所 === 96 === In this study, we propose a low-pass filter structure based on stepped-impedance low-pass filter, and a distributed parallel resonance circuit is used. The circuit has a section of high-impedance transmission line, that cascades another one with low-impedance, shunt with a coupled capacitor connecting with the terminals of two low-impedance lines. We can cancel the zero and the pole in band by using the variance of filter parameter.
