ABSTRACT:
A coaxial transmission line to waveguide transition is formed of two waveguide portions disposed on opposing sides of, and enclosing a portion of, a flat plate structure. The enclosed portion of the flat plate structure includes a tapered slot extending through the flat plate structure leaving portions of the flat plate structure protruding into the waveguide as loading ridges which provide impedance matching (transformation) between the coaxial line and the unloaded waveguide. The flat plate structure has a hollow therein and an inner conductor passing therethrough forming a coaxial line. The inner conductor crosses the tapered slot within the waveguide enclosure.
