Abstract
A broadband (8-18 GHz) radomed horn antenna system comprises a conical horn having broadband slots on the inner surface and a radome having a frusto-conical side wall and a spherically shaped transverse wall inserted into the horn. The radome wall is thin relative to operating wavelength. The radome side wall fits snugly against the inner surface of the horn wall so that transverse wall is proximate to the horn feed port with its convex side facing toward the horn aperture. The cylindrical feed guide contains a higher order hybrid mode suppressor which maintains a substantially uniform radiation pattern over the operating band with an acceptable insertion loss.
