摘要：
A dielectric resonator device includes a dielectric substrate (1). Electrode films (2,3) are formed on the front (1A) and back (1D) surfaces of the dielectric substrate (1), respectively. A TE010-mode resonator is constituted by two circular openings (4A,4B) which oppose each other and which are formed in the electrode films (2,3). Two opposing slots (5A,5B) formed in the electrode films (2,3) constitute a planar dielectric transmission line (PDTL). The PDTL is connected to the TE010-mode resonator. An excitation section (6) is formed by extending two portions (6A;6B) of each electrode film (2,3) on two side of each slot (5A,5B) into each opening (4A,4B).
