碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 98 === Dielectric resonator (DR), one of the key elements for microwave system is commonly applied in filters and oscillators. The characteristics of DR are mostly with high quality factor, high dielectric constant and low frequency-temperature coefficient. It has been used extensively to designing small size, light weight microwave filters. TE mode of a DR excited with magnetic filed from microstrip line is applied in the study. Since many other modes are also excited, the suppression of higher spurious modes is an important issue in preventing spurious responses. In this research effort, Ansoft High Frequency Structure Simulation (HFSS) and Agilent Advanced Design System (ADS) software were utilized for the simulation study. The obtain results agreed well with the measured results.
