Abstract
A UHF satcom antenna comprises a hollow cylinder; an annular substrate disposed on a base of the hollow cylinder; a circular substrate coplanar and concentric to the annular substrate; a plurality of bow-tie antenna elements; a plurality of rectangular antenna elements and a plurality of open-sleeve elements. The antenna system includes at least one feed line extending through the hollow cylinder and the circular substrate and electrically connects to the bow-tie elements. The hollow cylinder may comprise a dielectric material. Provided on the annular substrate, the bow-tie elements extend radially outward from the center of the annular substrate. The rectangular elements are electrically coupled to the plurality of bow-tie antenna elements and are provided on the outer surface of the hollow cylinder. Provided on both the annular substrate and the outer surface of the hollow cylinder, the open-sleeve elements act as parasitic antenna elements for the bow-tie antenna system.
