Abstract
A low specific absorption rate broadband antenna assembly for use with a wireless communication device. The antenna assembly includes a driven element and a parasitic element which are operatively connected to a radio frequency input/output port and a ground plane, respectively, and which are superposed above a predetermined region of a ground plane having a predetermined configuration. The driven and parasitic elements may take the form of traces or wires which are disposed away from each other by a distance related to the frequency of operation. The traces may be formed on one side of a suitable dielectric substrate such as a printed circuit board, while the wires may be self supporting and not requiring a dielectric substrate.
