Claims

[Scope of utility model registration request]

A 3dB power divider, two phase shifters for changing the phase of two radio waves configured by this 3dB power divider, and a 3dB directional coupling for combining the two radio waves that have passed through these phase shifters. The 3 dB power divider includes a rectangular waveguide, a tapered or step-shaped metal plate parallel to a wide surface of the rectangular waveguide, and the metal plate. 3dB with a tapered or step-shaped radio wave absorber plate connected to
As a power divider and as a variable phase shifter, two waveguide capacitive metal post-loaded phase shifters are stacked in the direction of the electric field so that the tube axes are parallel to each other and the direction of the electric field is the same. As a 3 dB directional coupler, two waveguides are stacked in the direction of the electric field, and two slots are inserted in the tube axis direction of the common wall surface perpendicular to the electric field of these two waveguides. A variable power divider characterized in that it is constructed using 3 dB top wall waveguide type directional couplers arranged symmetrically at the ends of a wide surface.
