Abstract
The invention utilizes small, narrow-band and frequency adaptable antennas to provide coverage to a wide range of wireless modes and frequency bands on a host wireless device. The antennas have narrow pass-band characteristics, require minimal space on the host device, and allow for smaller form factor. The frequency tunability further allows for a fewer number of antennas to be used. The operation of the antennas may also be adaptably relocated from unused modes to in-use modes to maximize performance. These features of the antennas result in cost and size reductions. In another aspect, the antennas may be broadband antennas.
