Abstract (en)
[origin: WO2007045665A1] A multiple resonant antenna unit (AT2) comprises a current feed area (SPI) from which only a single, spiral-like antenna branch (AZI) emanates. The total course of this spiral-like antenna branch (AZI) forms a first resonant antenna structure for a low frequency range and at least one partial section (SE15) inside the total course of this spiral-like antenna structure (AZI) forms a second resonant antenna structure for a higher frequency range.
