A versatile ultra high frequency radiofrequency identification (UHF RFID) antenna system is proposed. Spatial, polarization and radiation pattern diversity is demonstrated with a very reduced number of components. The diversity contribution of such an antenna is then characterized in terms of radio coverage in a RFID portal environment. Radio coverage in complex environment is greatly improved compared to the classical geometry.
