Zusammenfassung:An RFID transponder includes an antenna, including a radiating element or elements, a parasitic radiating element or elements, the radiating element being matched to create a first polarization vector to be excited. The parasitic radiating element is arranged to sweep round the antenna at proximity of the radiating element so that the parasitic element is extending on two to all sides of the radiating element. The parasitic radiating element is matched to create a second polarization vector to be excited, the second polarization vector being perpendicular to the first polarization vector.
