Abstract
A dielectric resonator device includes a dielectric substrate. Electrode films are formed on the front and back surfaces of the dielectric substrate, respectively. A TE010-mode resonator is constituted by two circular openings which oppose each other and which are formed in the electrode films. Two opposing slots formed in the electrode films constitute a planar dielectric transmission line (PDTL). The PDTL is connected to the TE010-mode resonator. An excitation section is formed by extending two portions of each electrode film on two side of each slot into each opening.
