Transition element between electromagnetic waveguides, especially between a circular waveguide and a coaxial waveguide

摘要

According to the invention, the transition element for electromagnetic waveguides is of the type intended to afford the transition between a circular waveguide (21) and a coaxial waveguide (25), and consists of a circular outer guide (31) cooperating with an inner conductor (33) forming an end portion of the central conductor (23) of the coaxial waveguide (25), the inner conductor (33) having at least one intermediate transition step (34, 35) of substantially constant cross-section throughout its length. …??It applies in particular to the construction of two-band duplexers. …IMAGE…
