Abstract
A dielectric filter has a first input/output port, a second input/output port, an even number of dielectric resonators, and a capacitor for capacitively coupling the first input/output port and the second input/output port. The even number of dielectric resonators are provided between the first input/output port and the second input/output port in circuit configuration, and are configured so that two dielectric resonators adjacent to each other in circuit configuration are magnetically coupled to each other.
