<p>An antenna is specially adapted for a portable electronic device, such as a hand-held computer or cell phone, having a conductive metal housing surrounding a radio transceiver. A rectangular recess is formed in one surface of the housing, and an elongated printed circuit board is placed along an inner wall of the housing. A coaxial cable coupled to the transceiver enters the housing, and an outer shield of the cable is connected to the inner wall of the housing along a substantial length of the cable. A center conductor of the cable is connected to a conductive layer of the printed circuit board. The recess is enclosed by a window that is substantially transparent to RF energy. RF energy radiated from the printed circuit board is capacitively coupled to a sheet of conductive material, and the RF energy is then radiated from the conductive sheet.</p> |
