Abstract
The invention discloses a retractable antenna system for wireless communication devices. The invention allows the entire antenna assembly, including ground plane and impedance matching circuitry, to be moved away from the wireless communication device and extend beyond any housing, such as a portable computer, to improve antenna performance. The disclosed embodiments include movable sections which can move the ground plane and active radiating element of the antenna outside a housing which encloses or partially encloses the communication device, such as when a PC Card cellular modem is placed within the housing of a laptop or notebook computer. Other embodiments include sections which are detachable from the wireless communication device.
