Abstract: A dielectric resonator filter comprising a metal wall (11) that is configured with metal cavities. Dielectric resonators (12, 14, 15) and (16) can be placed in the metal cavities and configured as a set of cylindrical TE mode resonators (12) and (14) and a set of rectangular HE mode resonators (15) and (16). Separating walls (13) are disposed between the dielectric resonators (12, 14, 15) and (16), which include tunable irises (17) for electromagnetic mixed coupling between the cylindrical TE mode resonators (12) and (14) and the rectangular HE mode resonators (15) and (16). The rectangular HE mode resonators (15) and (16) are configured to push far up the TE mode in frequency. This leads to an easy separation of two degenerate HE modes, a wide spurious free stop band and also achieves electric coupling without using any additional coupling member.

Abstract: A half wave dielectric resonator assembly including a resonator cavity having a top surface and a bottom surface, an elongated cylindrical dielectric resonator positioned within said resonator cavity and first and second insulative supports to couple and insulate the ends of the cylindrical dielectric resonator from the resonator cavity. The dielectric resonator has a substantially small diameter to length ratio. The resonator assembly provides improved spurious performance and quality factor (Q) at a lower mass. A resonator filter is constructed using a plurality of these resonator assemblies, where adjacent pairs of said resonator cavities are separated from each other by a common cavity wall. By forming a first iris opening formed within a first common cavity wall and forming a second iris opening formed within a second common cavity wall having a position that is vertically offset from the position of the first iris, it is possible to reduce stray coupling.

Abstract: A dielectric resonator device includes two dielectric resonators resonating in first and second resonant modes and a partitioning plate which partitions the two dielectric resonators. Slits S are provided in the partitioning plate. A magnetic loop of the first resonant mode (TE01δz mode) is directed along the length of the slits S. The partitioning plate is also provided with a conductor loop consisting of first and second conductor loop portions that are coupled to magnetic fields of the second resonant mode (TE01δy mode). Accordingly, the coupling of the second resonant mode between the two dielectric resonators can be suppressed by the coupling of a leakage of the magnetic fields passing through the slits S and the coupling of the magnetic fields by the provision of the conductor loop.
