Title:
TRIPLE MODE DIELECTRIC RESONATOR FILTER, MANUFACTURING METHOD THEREFOR, AND BANDPASS FILTER USING DIELECTRIC RESONATOR AND NRN STUB
Document Type and Number:
WIPO Patent Application WO/2018/212570
Kind Code:
A1
Abstract:
A triple mode dielectric resonator filter according to the present invention comprises: a dielectric resonator positioned in a cavity of a housing and formed perpendicular to a longitudinal direction of the housing; a dielectric support coupled to the dielectric resonator through a bonding process and mounted and fixed by means of a fixing screw passing through a screw fixing mounting hole in the cavity of the housing to support the dielectric resonator at a constant height; and a plurality of compensation blocks formed to protrude at regular intervals on a side surface of the dielectric resonator to allow the dielectric resonator to operate in a triple mode. Accordingly, provided is a triple mode dielectric resonator filter capable of realizing a resonator operating in a triple mode by forming compensation blocks in a dielectric resonator. In addition, a bandpass filter composed of a dielectric resonator and an NRN stub achieves improved insertion loss and a stable structure compared to a conventional bandpass filter using an NRN stub, and at the same time, it is possible to reduce the size thereof by at least 30% as compared with a conventional bandpass filter or a band-stop filter composed of only a triple mode dielectric resonator, and the bandpass filter has an effect of improving high compression characteristics.
