Abstract: A wideband, coaxial orthogonal-mode junction or OMJ coupler (420) is disclosed. The OMJ coupler (420) includes a coaxial waveguide (420A) having two or more ridges (460), two or more sectoral waveguides (420B,462) having a corresponding number of ridges or T-septa (460) as the coaxial waveguide (420A), and a mechanism for converting (470) the coaxial waveguide (420A) into the sectoral waveguides (420B) formed inline with the coaxial and sectoral waveguides (420A,420B). The converting mechanism preferably includes at least two metal fins (470) symmetrically disposed in the coaxial waveguide (420A) and coupled to the sectoral waveguides (420B). Optionally, the metal fins (1270) are tapering in shape. More preferably, there are four metal fins (470, 1270), four sectoral waveguides (420B), and four ridges or T-septa (460) in the coaxial and sectoral waveguides (420A, 420B).
