Abstract
A retractable antenna system is disclosed that enables electronic devices to engage in wireless communication. A preferred embodiment includes a retractable antenna disposed within a cavity in the electronic device and an actuating mechanism for selectively extending and retracting the antenna from within the cavity. The antenna system is preferably disposed within the housing of a communications card such as a PC Card. The retractable antenna may be rigid or flexible, and may be a single piece design or telescopic. The antenna system may also include two or more retractable antennas, a light source attached to the antenna, a control mechanism used to determine antenna functionality based on the positioning of the antenna, and the retractable antenna may be connected modular portion of the communication card.
