Abstract
An open slot antenna is formed in a planar conductor on a dielectric substrate. A tuning circuit is disposed toward an open end of the slot antenna and is used to select a resonant frequency of the antenna by electrically connecting one of multiple tuning elements across opposing sides of the slot. The tunable antenna so constructed may be incorporated into a handheld mobile communication device that can be operated in different geographic regions, each having different regional communication standards under which mobile communications are conducted.
