Radio Frequency Identification (RFID) is widely developed this last past years. It's consist on identify devices automatically and in real time by radio waves. One of the frequency band allocates for RFID applications is in the UHF band (860-960MHz). Nevertheless UHF RFID systems have a relatively narrow band-pass. To enhance it there are actually some research which applied Ultra Wide Band (UWB) technologies for RFID applications [1]-[3]. UWB systems offers several advantages as high data rate, localization and tracking, low power consumption, low cost, immunity to multi-paths, small sizes etc.. . One application to have a tag which can works on UHF RFID and UWB band is to feed the UWB chip thanks to UHF antenna and to respond in UWB band. In this paper we submit two antennas' prototypes, one for readers and the second one for tags. Reader and tag's antennas are designed to work in all UHF RFID band (860-960MHz) and European UWB band (6-8.5 GHz). Specifications, simulations, measures and perspectives are presented.
