Abstract
A waveguide to microstrip converter allowing size reduction as well as providing good cross polar discrimination and input VSWR characteristic. The waveguide to microstrip converter includes a structure of an orthogonal transducer formed of a circular waveguide and a rectangular waveguide integrally formed with and orthogonal to the circular waveguide. A first probe and a second probe are respectively coupled to the circular waveguide and rectangular waveguide. An output terminal of the first probe and an output terminal of the second probe are formed on the same plane and connected to respective microstrip lines.
