Abstract
An antenna system comprising a plurality of dipole elements formed from a single piece of material. The plurality of dipole elements is attached to a reflector plate with a single supporting base and forms horizontally or vertically stacked radiation elements. Tabs located between the center of the single piece and legs of the dipole elements and are bent at an angle to form a symmetrical axis in the center of slots separating the plurality of dipole elements to attenuate the radiation caused by current flowing around the slots. The plurality of dipole elements are selected to achieve different radiation patterns and can be formed into different shapes to achieve different lobe shapes.
