摘要
To reduce sidelobes in the radiation pattern of a phased array dipole antenna, a plurality of parasitic antenna elements are provided adjacent to the array of dipole elements of the antenna. The driven elements of the dipole array and associated director elements are formed as patterned conductor elements on one surface of a thin dielectric substrate. Feed elements for the driven dipole array also comprise patterned conductor elements formed on an opposite surface of the substrate. The feed elements have a geometry and mutually overlapping projection relationship with the conductors of the driven dipole elements, so as to form a matched impedance transmission line through the dielectric substrate with the patterned dipole elements. The parasitic elements are formed on additional dielectric substrates spaced apart from and parallel to the thin dielectric substrate upon which the driven dipole array is formed.
