Abstract
The present disclosure presents a dual-channel filter based on a dielectric resonator, which includes a metal cavity, a dielectric resonator, two tuning metal probes, and four feeding metal probes. The dielectric resonator is disposed at the center of the metal cavity. The four feeding metal probes are disposed around the metal cavity, and coupled to the dielectric resonator. The two tuning metal probes are connected to the metal cavity, and respectively located at a central position directly above and below the dielectric resonator. The dual-channel filter integrates two channel filters with good isolation between them, and has two input ports and two output ports.
