ABSTRACT:
A transition element for electromagnetic waveguides of the type designed to provide for the transition between a circular waveguide and a coaxial waveguide, constituted by a circular external guide cooperating with an internal conductor forming an end portion of the central conductor of the coaxial waveguide, the internal conductor having at least one intermediate transition step with a substantially constant section throughout its length. The device can be applied notably to the making of two-band duplexers.
