A novel structure for launching the fundamental mode in rectangular waveguides is proposed. The geometry consists of a cavity–backed circluar patch radiating into a rectangular waveguide. The matching properties of the proposed component are comparable with the ones of the classically used L–shaped loop end–launcher. The structure
results in a very compact, colinear transition from a standard coaxial connector to a rectangular waveguide. The component has applications as general purpose coaxial–to–waveguide transition and is well suited for low–profile phased–array antennas.
