Abstract
An antenna mounted on and retractable into a casing of a portable radio communication apparatus. When the antenna is pulled out of the casing, it plays the role of a .lambda./2 whip antenna. Even when the antenna is retracted into the casing, it has substantially the same gain as when pulled out from the casing.
