Abstract

The invention provides a dielectric resonator, a dielectric filter and communication equipment. A first hollowed-out groove and a second hollowed-out groove are formed in an area adjacent to a first end face and an area adjacent to a second end face through a dielectric block respectively, the dielectric block is equally divided into two parts in the direction perpendicular to the length direction, and the geometric center of the part where the first end face is located is located in the first hollowed-out groove. The geometric center of the part where the second end face is located is locatedin the second hollowed-out groove, so that the ratio of the secondary resonant frequency to the fundamental mode resonant frequency of the dielectric resonator is increased, the out-of-band harmoniccharacteristic of the dielectric filter is improved after the dielectric resonator is applied to the dielectric filter, and the dielectric resonator is simple in structure, easy to form and suitable for mass production.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a dielectric resonator, a dielectric filter and communication equipment. Background technique [0002] With the rapid development of communication technology, the application of 5G communication technology is becoming more and more extensive. Filters are important components in 5G communication systems. Highly integrated, miniaturized, lightweight, and low-cost filters are an inevitable requirement of 5G communication technology. [0003] In the prior art, ceramic materials with high dielectric constant are generally used to prepare resonators with cuboid structure to form filters that meet the above requirements, but the resonant frequency of the resonator with this structure is closer to the fundamental mode resonant frequency , the ratio of the two is low, resulting in low far-end out-of-band characteristics of the filter.
