Abstract
An antenna system for a communication card provides wireless or radio frequency (RF) communication with other networks or communication systems. The antenna system includes an antenna attached to a retractable platform that is selectably movable between an extended position and a retracted position. When wireless communication is desired, the retractable platform is located in the extended position and the antenna is substantially disposed outside of the body of the communications card. When wireless communication is not desired, the retractable platform and antenna are stored inside the body of the communications card in the retracted position. Desirably wireless communication is automatically available when the retractable platform is in the extended position, and wireless communication is automatically unavailable when the retractable platform is in the retracted position.
