PURPOSE:To obtain a polarized dielectric resonator without addition of a special component for coupling resonators. CONSTITUTION:A groove is formed to adhesive faces of dielectric boards 2, 3, inner conductors 16-19 are provided to the inner face and coupling electrodes E13, E14 are formed to another dielectric board 4. The three dielectric boards 2, 3, 4 are coupled, then the coupling electrode E13 makes capacitor-coupling to inner conductors 16, 17 and the coupling electrode E14 makes capacitor- coupling to inner conductors 18, 19. As a result, a ground electrode (outer conductor) 12 is formed almost on the entire face of the rear side of the dielectric board 4 to prevent the reduction in the Qo of the resonator and leakage of the electromagnetic field. Thus, the polarized integrated band pass filter is easily obtained with a low insertion loss. |
