Abstract
A dielectric resonator apparatus includes a plurality of TM double-mode dielectric resonators. Each dielectric resonator has a dielectric rod-complex, a casing provided with electrically conductive film at the outside surfaces, and metal panels covering the upper and lower openings of the casing. In adjacent TM double-mode dielectric resonators, at portions of the planes of the two casings opposing each other, apertures are provided in the direction of the magnetic field generated by two dielectric rods which have the same axial direction. A coupling member is also provided so as to form an electrically conductive loop which goes across the magnetic field.
