Abstract: This disclosure describes a dielectric filter and a communications device. In one example, the dielectric filter includes at least two dielectric resonators, a first through-hole is disposed between at least one pair of adjacent dielectric resonators, and the first through-hole is configured to cut a magnetic field between the at least one pair of adjacent dielectric resonators. In some implementations, a magnetic field distribution in the dielectric filter may be cut via the first through-hole, so that a magnetic field distribution area is reduced, and a high-order harmonic wave frequency can be increased, thereby improving a remote suppression capability and meeting the specification requirements.

Abstract: This application provides an example dielectric filter and an example communications device. The dielectric filter includes a dielectric block. At least two resonant through holes that are parallel to each other are provided in the dielectric block. The resonant through hole is a stepped hole. The stepped hole includes a large stepped hole and a small stepped hole that are arranged coaxially and that are in communication. The small stepped hole passes through a first surface of the dielectric block. The large stepped hole passes through a second surface of the dielectric block. A stepped surface is formed between the large stepped hole and the small stepped hole. The surfaces of the dielectric block are covered with conductor layers. The conductor layers cover the surfaces of the dielectric block and inner walls of the large stepped hole and the small stepped hole. A conductor layer of the inner wall of the large stepped hole is short-circuited with a conductor layer of the second surface. A conductor layer of the inner wall of the small stepped hole is short-circuited with a conductor layer of the first surface. A loop gap that does not cover the conductor layers is provided on the stepped surface. The loop gap is arranged around the small stepped hole.
