Abstract
An antenna system in which a conical shaped metallic radome has a surface composed of a periodic array of radiating slot elements. Each slot element has three arms connected to each other and extending radially outward with the angular distance between adjacent arms equal to 120°. The slot elements are aligned in order to have each of the arms in an element parallel to an arm in an adjacent element forming a uniform periodic array.
