Claim:
1. A dielectric waveguide input/output structure for connecting to a coaxial connector a plurality of dielectric waveguide resonators each comprising an approximately parallelepiped-shaped dielectric block, wherein the plurality of dielectric waveguide resonators include a first dielectric waveguide resonator and a second dielectric waveguide resonator each having an exterior surface coated with an electrically conductive film, except for one side surface in which a coupling window is provided, wherein a linear-shaped probe composed of the electrically conductive film is formed in the coupling window, the probe having two ends, one of the two ends is connected to a feeding point which is formed on an edge of the one side surface and insulated from the electrically conductive film, and the other of the two ends is connected to a portion of the electrically conductive film around an outer periphery of the coupling window, wherein the first dielectric waveguide resonator and the second dielectric waveguide resonator are arranged in such a manner that the one side surfaces thereof are facing to contact each other to allow the coupling windows thereof to be aligned with each other, and wherein the coaxial connector is mounted on the feeding point.
