Abstract
Antenna means for a portable radio communication device is disclosed. It includes a radiating first element having a meander geometry being relatively flat and without any complete loops or turns, a radiating second element having a meander, helical, rectangular or straight geometry. The first and second elements interact to provide one or more modes of antenna operation and the first element feeds the second element in at least one operational mode. Further, an extendable and retractable feature of the second element is disclosed, as well as an antenna adapter for external connection of the inventive antenna means to an auxiliary antenna.
