Coupling Parameters Between a Dielectric Resonator and a Microstripline

Abstract

The coupling coefficient between a microstripline and the dipolar magnetic (TE/0gamma delta/ ) mode of a cylindrical dielectric resonator is evaluated by using two methods numerical and analytical. Theoretical and experimental extenal quality factors, as well as the scattering matrix parameters which consider the substrate material, the ground plane, and the distance between the line and the resonator, are presented.
