Abstract
A method uses a rack and gear system for retracting an antenna when a wireless device is opened. Particularly, sliding a cover to open the device moves first and second sliding racks attached on opposite sides of the sliding cover. The racks drive a first gear and a second gear, respectively. The first gear drives an antenna rack. An antenna is attached to the antenna rack, such that driving an antenna rack extends or retracts the cover.
