ABSTRACT:
A drawer (70) and antenna (e.g., 78) can be extended from a computer for wireless communications, and retracted when not in use. The antenna and its circuit board (56) are slidably attached to the drawer, which is slidably attached to an antenna housing (30) located within the computer. A door (74) is pivotally attached to a bottom plate (60) of the drawer to cover a slot (40) in the side of the computer. For wireless communications, the antenna, circuit board and drawer are extended through the slot and project out the side of the computer. The bottom plate, door and a cover over the circuit board function as a ground plane for the antenna. The effective dimensions of the ground plane can be varied by sliding the circuit board relative to the drawer.
