Dielectric Waveguide Filter And Dielectric Waveguide Duplexer |
摘要 |
Dielectric waveguide comprising 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. |

1. A dielectric waveguide filter, comprising:
a substrate comprising a core material having upper and lower surfaces, each formed with a conductor pattern; and a plurality of resonator groups disposed on the 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. |
