A dual polarized broadband, lightweight, low cost tapered slot antenna which has first and second radiating tapered slot antennas which are co-located and positioned perpendicular to one another. Each antenna includes a relatively thin dielectric substrate and a radiating metallic antenna element mounted on the upper surface of the dielectric substrate. A tapered notch area, which is centrally located, is etched away to expose the dielectric substrate. The tapered slot antennas allow for linear polarization, elliptical polarization and circular polarization.
