Abstract
A square waveguide () has four ridges (). The cross section of the square waveguide () perpendicular to a waveguide axial direction is square. Inside the square waveguide (), two rectangular waveguide terminals () are formed by partitioning the inside along the waveguide axial direction. A septum phase plate () formed to get narrower stepwisely as its gets closer to a square waveguide terminal () opposite to the rectangular waveguide terminals () is provided. A projecting portion () is provided on a part of a ridge () formed on a ridge-side wall surface opposite to a wall surface, the septum phase plate () being joined to the wall surface in a part where the septum phase plate has largest width, the projecting portion () being larger than other parts of the ridge () in a cross-sectional shape perpendicular to the waveguide axial direction.
