A near-horizon antenna structure includes an upper radiating element having a straight conductive trace disposed on a planar surface of a non-conductive substrate, a rectangular lower radiating element serving as a ground plane disposed on the planar surface, and a feed point provided between the upper and lower radiating elements. When the planar surface is positioned vertically, the far-field effects of horizontal current flowing in opposite directions on the radiating elements cancel to provide an antenna pattern with increased gain in horizontal directions and reduced gain in vertical directions. A flat panel display and a portable communication device are also provided with one or more near-horizon antenna structures integrated therein.
