Abstract

In this letter, a triple-mode bandpass filter based on a hollow silver-loaded ring-shaped dielectric resonator (RSDR) is designed by combining a dominant TE_01δ mode with a high-order degenerate HE_11δ pair. Because of the distinct E-field distribution, the frequencies of the HE_11δ pair can be pulled down and split using a loaded silver segment on top of a dielectric. Moreover, the silver segment has a negligible effect on TE_01δ and higher order TM_01δ modes, implying separation between a passband and adjacent interferers. To validate the methodology, a prototype silver-loaded RSDR is excited by the two L-type feeding probes to satisfy the requirements of coupling strengths for different modes.
