Title:
DIELECTRIC RESONATOR AND DIELECTRIC FILTER, TRANSCEIVER AND BASE STATION USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/107478
Kind Code:
A1
Abstract:
The present application relates to communication device components, and in particular to a dielectric resonator and a dielectric filter, a transceiver and a base station using same. Embodiments of the present application provide a dielectric resonator, comprising a dielectric block made of solid dielectric materials; the surfaces of the dielectric block are covered with conducting layers; two adjacent surfaces of the dielectric block are provided with a hole or notch, individually; the hole or notch on one surface is communicated with the hole or notch on the other surface, and the inner surface of the hole or notch is covered with the conducting layer. The dielectric resonator provided by the embodiments of the present application aims at achieving convenience of adjusting coupling coefficients and resonant frequency, and ensures miniaturization of the dielectric resonator at the same time of obtaining broadband coupling so that the dielectric filter, the transceiver and the base station using the dielectric resonator achieves broadband and miniaturization to satisfy broadband and miniaturization requirements of wireless base stations.
