Title:
DIELECTRIC WAVEGUIDE FILTER
Document Type and Number:
WIPO Patent Application WO/2021/008006
Kind Code:
A1
Abstract:
The present invention relates to a dielectric waveguide filter, which comprises two adjacent resonators; each resonator comprises a dielectric body and a shielding layer which wraps the outer surface of the dielectric body, each resonator is provided with a frequency blind hole, and the inner surfaces of the frequency blind holes are provided with the shielding layers; a negative coupling blind slot is provided between the two resonators, and the negative coupling blind slot changes the coupling between the two resonators into capacitive coupling. In the present invention, capacitive coupling is achieved by means of providing a negative coupling blind slot, which thus reduces the weight of the filter.
