Patent ID: 8111115

Claim:
A dielectric resonator assembly for use in a dielectric resonator filter or a dielectric resonator multiplexer, the dielectric resonator assembly comprising: a) a dielectric resonator; b) the dielectric resonator formed in a unitary piece of high-permittivity dielectric substrate into a half-cut cylinder of a selected height and a selected diameter, the half-cut cylinder defined by a parallel pair of semi-circular surfaces, a curved surface extending along respective curved edges of the pair of semi-circular surfaces, and a rectangular surface subtending the curved surface, wherein a first dimension of the rectangular surface corresponds to the selected height and a second dimension of the rectangular surface corresponds to the selected diameter; wherein the dielectric resonator resonates in a plurality of resonance modes comprising a ½HEH11 mode and a ½HEE11 mode and, at the selected height and the selected diameter, the dielectric resonator resonates in one of a dual mode or a dual band so that each of the ½HEH11 mode and the ½HEE11 mode are operating modes of the dielectric resonator assembly.
