Abstract:
An antenna means for transmitting and receiving RF signals adapted for a mobile radio communication device comprising:a ground plane means arranged to be connected to ground of the circuitry of a radio communication device,a conductive radiating structure having a shape of a band,the conductive radiating structure having a first A and a second B essentially parallel, closely spaced and opposed surfaces,the radiating structure having in a first end a feed portion arranged to be coupled to circuitry of the radio communication device,the radiating structure having a second end being a free end, whereinthe conductive radiating structure being divided by bent portions into a number of sections along its length,the first surface A of a first section of said sections facing the first surface A of a second section of said sections, being consecutive to the first section, andthe second surface B of a third section facing the surface B of a consecutive section,wherein the radiating structure has a flexibility so as to enable the radiating structure to be compressed, whereby at least two of the sections are connected to each other, in order to short-circuit the radiating structure and thus making it inoperative, and further to be expanded to disconnect the connection between the sections, in order to make the antenna means operative.
