Abstract
An antenna that functions as an approximately balanced antenna that is structurally asymmetric but electrically symmetric includes a first antenna element that is extendable and retractable, a second fixed antenna element, an unbalanced transmission line feeding the first and second antenna elements, and a balanced-unbalanced convertor. At a time of extending the first antenna element, the first and second antenna elements are supplied an electric power from the unbalanced transmission line through the balanced-unbalanced convertor, so that the first and second antenna elements cooperate to function as an antenna.
