ABSTRACT:
Integrated (embedded) tri-band antennas for use with portable devices such as laptop computers. In one aspect, an integrated tri-band antenna for a portable device comprises a first element having a resonant frequency in a first frequency band, a second element having a resonant frequency in a second frequency band, a third element having a resonant frequency in a third frequency band, and a ground element for grounding the first, second and third elements. The first, second and third elements and ground element may be metallic elements formed on a PCB (printed circuit board), wherein the first element is connected to a signal feed, and wherein the PCB is mounted to a metallic support frame of a display unit of the portable device.
