Abstract

PURPOSE:To make the coupling between a rectangular waveguide and a dielectric resonator close easily, by providing symmetrical ridges in the tube of the rectangualr waveguide. CONSTITUTION:Symmetrical ridges 4a and 4b are provided in the tube of a rectangular waveguide 3, and a discoidal dielectric resonator 6 is arranged near a space 5, which is interposed betwen these ridge conductors, oppositely to these ridges so that the disc surface is parallel with the E face of the rectangular waveguide 3. The dielectric resonator 6 is supported by a supporting member 7 consisting of quartz glass or the like, and a memeber 8 for adjusting finely the resonance frequency is inserted from the wall of the E face side of the waveguide through the hollow part of the supporting member 7. Consequently, the electromagnetic field energy in the waveguide is concentrated near the space 5 interposed betwen ridge conductors 4a and 4b, and directions of the microwave magnetic field near the space 5 between ridges and the microwave magnetic field of a minimum frequency mode of the dielectric resonator 6 coincide with each other near the dielectric resonator 6, and thus, coupling becomes close sufficiently.
