A flared feed horn including a plurality of signal lines deposited on a bottom surface of a substrate and forming part of a TEsum mode launcher, a ground plane deposited a top surface of the substrate, and an outer conductor electrically coupled to the ground plane and having an internal chamber, where the conductor includes a flared portion and a cylindrical portion. The outer conductor includes an opening opposite to the substrate defining an aperture of the feed horn. The feed horn also includes an embedded conductor positioned within the chamber and being coaxial with the outer conductor, where the embedded conductor is in electrical contact with the plurality of signal lines. The feed horn also includes a TEdifference mode launcher electrically coupled to the outer conductor proximate the aperture.
