Abstract
An antenna includes two radiators that are co-planar and exhibit mirror symmetry about an axis. Each radiator includes a half-Vivaldi sub-radiator bounded by a first curved edge and a first straight edge adjacent to the first curved edge. Each radiator also includes a curved monopole sub-radiator that is bounded by a second curved edge and a second straight edge adjacent to the second curved edge. The first and second straight edges coincide such that the first and second curved edges are continuous. When the antenna is driven at relatively high frequencies, the half-Vivaldi sub-radiators cooperate to act like a planar Vivaldi antenna. At lower frequencies, the curved monopole sub-radiators cooperate to act like a planar dipole antenna. Two of these antennas may be fabricated on circuit boards that intersect to form a dual-polarization antenna system.
