    Abstract: [Technical Problem]
    A dielectric waveguide filter comprising resonators coupled via a coupling window is likely to cause, at the time of arranging the resonators, an error in the position or dimension of the coupling window due to positional displacement, or leakage of electromagnetic field from the coupling window due to a gap generated between the resonators, leading to degradation of frequency characteristic. A dielectric filter provided with constricted portions has the drawback of being difficult to be applied to a filter in which connection between resonators is complicated.
    [Solution to the Problem]
    A dielectric waveguide filter is provided, which comprises a plurality of resonator groups disposed on a substrate, wherein each of the resonator groups comprises one or more integrally-formed resonators, each obtained by coating a dielectric body with a conductor film, wherein each resonator group in at least a set of resonator groups of the plurality of resonator groups comprises waveguide-side slot exposing the dielectric body in a bottom surface thereof, wherein the substrate comprises a cavity surrounded by conductor patterns formed in the upper and lower surfaces, and by a via hole connecting the conductor patterns in the upper and lower surfaces, wherein the cavity comprises a set of substrate-side slots exposing the core material, the set of substrate-side slots being provided at a position to which waveguide-side slots of the set of resonator groups are opposed, and wherein resonator groups in the set of resonator groups are coupled together via the cavity.

    Abstract: A transverse magnetic (TM) mode dielectric filter includes an enclosure, a dielectric resonator, a main cover, and an elastic component, where the dielectric resonator is disposed in a resonant cavity of the enclosure; the main cover is secured between the elastic component and an open end of the enclosure; the elastic component includes multiple elastic flaps; the multiple elastic flaps are evenly distributed around an axial direction of the dielectric resonator; one end of each of the elastic flaps is fixedly connected to the main cover, and free ends of the elastic flaps elastically act on a central part of an outer surface of the main cover, to provide an elastic force towards the dielectric resonator. The evenly distributed multiple elastic flaps produce a pressure towards the dielectric resonator so that a uniform and stable pressure is produced around the dielectric resonator, to ensure a uniform current density inside the resonant cavity. In this way, intermodulation performance can be greatly improved and kept stable in a long term; the main cover fits with the enclosure and the dielectric resonator in an adhering manner; and the elastic component is disposed on the outer surface of the main cover, the elastic component does not need to be electroplated, and high precision is not required, thereby reducing processing costs.
