A Novel and Accurate Method for the Design of Dielectric Resonator Filters

The development of numerical techniques now permits us to analyze complex structures such as dielectric resonator filters and planar passive elements for coplanar monolithic microwave integrated circuits. In this paper, we describe a novel method for designing dielectric resonator filters. Then a Chebychev band pass filter is designed by coaxially placing high-Q TM015 dielectric resonators in a cutoff circular waveguide. In the present work, discussions are made regarding high-Q resonators and inter-resonator coupling.
