Abstract
A highly conductive fiber reinforced tubular antenna is composed of metal coated reinforcing fibers in a composite structure. The conductive fibers may be disposed in a tubular or cylindrical fashion unidirectionally parallel to or at an angle to the axis of the tube or cylinder, thus providing multifunctional properties of strength and conductivity. Alternatively, the conductive fibers may be non-woven in configuration and disposed on one or more wrapped layers to form the antenna. The fiber reinforced composites disclosed are both lighter and stronger than their metal counterparts, while the highly increased conductive surface area in the composite creates enhanced electrical or electromagnetic performance than tubular or cylindrical antennas made of metal or nonmetal composite structures.
