Abstract:
An antenna array structure formed from a plurality of continuous transverse stub elements in a coaxial relationship, said array structure comprising:a plurality of cylindrical segments, wherein each of the plurality of cylindrical segments has a rim at a top end and at a bottom end, wherein each rim extends transversely away from the cylindrical segment relative to a longitudinal axis, wherein the plurality of cylindrical segments are longitudinally separated from each other, and wherein the plurality of cylindrical segments are comprised of at least a dielectric material;a core element parallel to the longitudinal axis and around which the plurality of cylindrical segments are disposed to thereby form a coaxial relationship therewith;wherein the plurality of cylindrical segments and the core element are coated with a thin and continuous conductive layer of material, and wherein a transverse stub element is formed from immediately adjacent cylindrical segments; anda coupling end which is electrically coupled to a first cylindrical segment of the plurality of cylindrical segments, and to the core element, to thereby provide a feed for received and transmitted signals.
