Numerical analysis of shielded dielectric resonators including substrate, support disc and tuning post

Abstract

An efficient numerical technique and computer program has been developed for the determination of the resonant frequencies and field coefficients of cylindrical dielectric disc resonators in a configuration which models the various effects present in real technical applications. It accounts for the influences due to shielding, planar circuit substrate, dielectric support and a dielectric post used to tune out fabrication tolerances.
