Input impedance and loaded quality factor of a probe exciting dielectric resonator

Using a dielectric resonator in microwave filter applications, several types of excitations can be considered. An HEM_{11 delta} -mode filter, used in satellite applications, utilises coaxial probes for the coupling of dielectric resonators with the external ports. The authors present the determination of the input impedance and of the coupling parameters between a probe and a dielectric resonator, when the pin is placed in the radial plane of a structure containing a cylindrical dielectric resonator.
