In this article, tag and reader multi-standards RFID antennas are presented. These antennas are matched on one the UHF RFID regulate frequency band (860-960 MHz) and on the ECC UWB frequency band (6-8.5 GHz). Tag is composed of two antennas, one match for the RFID applications with classical RFID input impedance, one for UWB matched at 50 Ω. Tag sizes are limited to credit card sizes (85x54 mm). Reader antenna is an association of a bowtie and a dipole antenna and it is matched on 50 Ω on twice bands. There is no sizes' specification for reader antennas. The substrate is FR4 0.8 mm thick for tag antennas and 1.6 mm for reader antennas. Epoxy's relative permittivity is 4.4 and its dielectric loss tangent is 0.02. Design rules, simulations, measures and perspectives are exposed.
