Abstract
An end portion (14a) of a center conductor (14) of a coaxial cable (16) protrudes transversely into a tubular waveguide (10) near an end thereof. A piston (22) having a stepped inner wall (24) closes the end of the waveguide (10). The inner wall (24) is formed with two or more steps (24a,24b,24c) which protrude axially into the waveguide (10) by different distances (L1,L2,L3), reducing the return loss and extending the bandwidth of the coaxial cable-to-waveguide transition.
