ABSTRACT:
The discone antenna includes a conical antenna element, having an apex, and a disc antenna element adjacent the apex of the conical antenna element. An inverted antenna feed structure, such as a flanged coaxial connector or coaxial cable, is connected to the disc and conical antenna elements and extends outwardly from the disc antenna element on a side thereof opposite the apex of the conical antenna element. The discone antenna with such an inverted feed structure facilitates an inverted positioning, for example, on vehicles, rooftops and/or control towers, etc., that will increase the bandwidth pattern in the direction of the potential target.
