Abstract
An antenna means to be mounted on a personal telephone is disclosed. The antenna means comprises a helical radiator, an elongated radiator extendable through the helical antenna, and a coupling means for activating the extendable elongated radiator, when in extended position. A more compact antenna means, with less need for receiving depth inside the telephone, is achieved by permitting the extendable elongated radiator, when in a retracted position, to extend at least partially inside the helical radiator. In the extended position the elongated radiator may be coupled to the telephone directly or via the helical antenna.
