Title:
DIELECTRIC RESONATOR AND DIELECTRIC FILTER
Document Type and Number:
Japanese Patent JP2019193074
Kind Code:
A
Abstract:
To reduce variation in resonance frequency due to variation in volume of a resonator body.SOLUTION: A dielectric filter 1 includes a plurality of dielectric resonators. The dielectric filter 1 includes: a plurality of resonator bodies 3A, 3B, 3C, 3D which comprise a first dielectric having a first dielectric constant and which correspond to the plurality of dielectric resonators; and a surrounding dielectric part 4 which comprises a second dielectric having a second dielectric constant smaller than the first dielectric constant and which is present around the plurality of resonator bodies 3A, 3B, 3C, 3D. Each of the plurality of resonator bodies 3A, 3B, 3C, 3D includes a plurality of individual elements 30 separated from each other.SELECTED DRAWING: Figure 1
