Abstract

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