Abstract
A dual-mode dielectric resonator using two dissimilar modes is described, the dissimilar modes supported by a ridge waveguide resonator and a ½-wavelength metalized cylindrical resonator within a single, metal-coated dielectric block. Each ridge waveguide resonator and cylindrical resonator form a resonator pair. Multiple pairs of ridge waveguide/cylindrical resonators are fabricated in the same dielectric block to form an 8-pole dielectric resonator filter for 5G or other applications. Transmission zeros can be positioned by the location of feeding probes along the cylindrical resonators.
