Analysis of dielectric resonators using the high-frequency structure simulator (HFSS) and its application to microwave filter design

摘要

Resonant frequencies of two types TM{sub}(01δ) mode dielectric resonators and the coupling coefficient between two dielectric resonators are computed by using the high-frequency structure simulator (HFSS), and compared with the calculated result by the mode-matching method and the measured result. As the result. calculation precision of HFSS is discussed. The external Q value of TM{sub}(01δ) mode dielectric resonator exicited by a coaxial line is also computed by using HFSS. A four-stage Chebyshev band-pass tilter is designed from these calculated results
