Analysis of dielectric loaded resonator dual-mode filter

Abstract

A dielectric loaded rectangular cavity for the design and realisation of different elliptic function filters topologies is presented. The 3-D Transmission Linee modelling method (TLM) is applied to the analysis of the cavity to obtain the resonant frequencies and couplings between the rectangular cavities. As an application to the analysis, a 4-pole elliptic function filter is designed and measured results presented.
