1. An antenna assembly for a hand-held radio frequency transceiver having a signal conductor and a ground conductor, said antenna assembly comprising:

  • a conductive ground plane element;

    a dielectric substrate element having a first surface, said first surface maintained a predetermined distance away from the conductive ground plane element; and

    a loop element disposed upon the first surface of the dielectric substrate element, said loop element having first and second ends disposed generally opposite each other, the signal conductor of the transceiver being coupled proximate said first end, and the ground conductor being coupled proximate said second end, said loop element having a plurality of side elements each having an associated width presented on the dielectric substrate, and wherein the widths of at least a pair of said plurality of side elements are substantially different.
