Abstract
An antenna structure may be formed by arranging a current-restricting structure upon a conductive surface. The current-restricting structure may be formed from a ferrite material, and may be in forms including a belt, tiles, or a patterned deposited layer. The conductive surface may be associated with a vehicle or structure. The current-restricting structure alters the paths taken by current on or beneath the conductive surface when a voltage is applied between portions of the surface.
