Abstract
A dielectric filter in which a desirable amount of coupling is obtainable, and the positions of an input coupling unit and an output coupling unit can be easily arranged. The dielectric filter includes a shield case, a dielectric resonator disposed inside the shield case, a supporting base for supporting the dielectric resonator, the input coupling unit, and the output coupling unit. Both the input coupling unit and the output coupling unit are coupled to the dielectric resonator. The output coupling unit is a probe with an open-circuited end, extending on a side where the supporting base of the dielectric resonator is disposed.
