BROADBAND WAVEGUIDE TO COAXIAL LINE TRANSITION

摘要

Transition apparatus for interconnecting a waveguide to a coaxial line comprising a first subassembly which forms the top, both side and end closing walls of a rectangular waveguide section and a second subassembly which provides the bottom wall thereof and has an impedance transforming section integrally formed therewith. This transforming section is in the form of a staircase and the first and top step thereof has an overhanging tab which confronts the end closing wall of the waveguide section. The center conductor of a coaxial connector attached to this end wall contacts the end face of the tab, and these elements together with the back of the staircase and an adjacent portion of the bottom wall define a magnetic field coupling loop.
