Abstract
A wide band biconical antenna with a helical feed system comprises a printed circuit board (PCB) that maintains a plurality of antenna elements having an entry conic and a termination conic arranged about a common axis. Each of the antenna elements receive a signal from a signal splitter via respective feed lines that each have the same physical length. In addition, the antenna system includes a matching system disposed within the ground plane formed by the entry conic of each of the antenna elements. The antenna elements are retained within retention sections that maintain helical support channels that allow the feed lines to be arranged in a helical manner about the antenna elements.
