Abstract :
This paper describes a novel very compact circular horn with high aperture efficiency. The horn presents a profile very waving to achieve the optimum waveguide mode conversion yielding an extremely reduced horn depth (about 1.2 time the aperture diameter) and an aperture efficiency greater than 90% over a 10% bandwidth for aperture dimensions up to 6λ.
