Abstract
The ultra-wideband unipole antenna is a variant on a monocone antenna, including a plurality of electrically conductive rods that act as a parallel inductive-capacitive (L-C) network for improving the impedance match between the radiating element of the antenna and the antenna's feed. An electrically conductive conical surface having a vertex end and a base end acts as the radiating element. The vertex end is positioned adjacent to, and spaced apart from, a ground plane plate. Each electrically conductive rod has opposed first and second ends, the first end being secured to the electrically conductive conical surface, and the second end being secured to the ground plane plate. A coaxial cable feed line has a center conductor and an outer conductor. The center conductor is in electrical communication with the vertex end of the electrically conductive conical surface, and the outer conductor is in electrical communication with the ground plane plate.
