Abstract:
1. A radio frequency identification tag adapted to work at a frequency between 850 MHz and 950 MHz, comprises: a dielectric core plate including a face side and a back side, and an inlay comprising a dielectric substrate, a planar inverted F antenna comprising two electrically conductive plates of different size, one attached to the face side of the dielectric core plate and the other to the back side of the dielectric core plate and either one of which is capable of being used as a ground plate and the other one is capable of being used as a resonating antenna element on a surface of the substrate, the plates being electrically connected by at least one short circuit element arranged on an outer surface of the dielectric core plate, and an integrated circuit on a chip electrically connected to the electrically conductive plates, the inlay being wrapped around the core plate so that one of the electrically conductive plates is attached to the face side of the dielectric core plate, and the other electrically conductive plate is attached to the back side of the dielectric core plate.
