Abstract
An antenna means for a portable radio communication device, in particular a hand-portable mobile telephone, having at least one radiating element that has a meandering and cylindrical configuration. This structure is specifically advantageous in combination with an extendable and retractable whip antenna and, when having two or more meandering radiating elements, in multi-band radiating structures. The antenna device is suitable for manufacturing in large quantities, for example by a flexible printed circuit board technique.
