In this paper, we present an UHF-RFID tag mountable on metallic surfaces and capable to operate in the assigned frequency bands in Europe (866{869MHz) and USA (902{928MHz). Due to the proximity of these frequency bands, the dual-band functionality can be achieved through a perturbation method applied to a single band tag designed to operate at the intermediate frequency. The tag consists of an integrated circuit, an impedance matching network (where the perturbation method is applied) and a patch antenna. The considered antenna has been chosen because it has high e-ciency over metallic surfaces. The whole tag has been analyzed, designed and flnally fabricated. The read ranges measured in free-space are 9.5m and 7.5m at the European and USA frequency bands, respectively. By placing the tag on a metal surface, the read ranges increase up to 14m and almost 11m, respectively.
