Abstract

PURPOSE:To reduce the generation of undesired waves in a simple structure by providing a metallic shelding plate in parallel to the electric field to constitute cut- off waveguides in a waveguide, which has one end short-circuited, and forming an evanescent-mode resonator. CONSTITUTION:Metallic shielding plate 10 is arranged in parallel to the electric field of waveguide 9, which has one end short-circuited, vertically to the magnetic field, and capacity-property tuning screws 11 to 18 which form evanescent-mode resonators 11 to 16 are provided in both sides of filters 31 and 32 divided by shielding plate 10. Further, coupling adjustment screws 17 to 26 which adjust the coupling of resonators 11 to 16 are provided. In another example, one or more dielectric resonators or MIC resonators are arranged in cut-off wave-guide 9 to constitute a small-size band pass filter where the generation of undesired waves is reduced similarly to the evanescent-mode resonator.
