RFID benefits and limitations are outlined in this work, showing some future challenges enabling RFID technology to play a key role in the Internet of Things. Some open issues and possible solutions are discussed to improve the reliability of RFID systems. In particular, the multipath phenomena is addressed, proposing metamaterial absorbers as a possible hardware solution for multipath reduction in indoor scenario. The potentialities of a fractal based metamaterial absorber are demonstrated. A very high versatile MA-cell is designed, offering both miniaturized sizes as well as multi-band and/or broad-band behavior, within the RFID UHF-band.

Abstract
RFID benefits and limitations are outlined in this work, showing some future challenges enabling RFID technology to play a key role in the Internet of Things. Some open issues and possible solutions are discussed to improve the reliability of RFID systems. In particular, the multipath phenomena is addressed, proposing metamaterial absorbers as a possible hardware solution for multipath reduction in indoor scenario. The potentialities of a fractal based metamaterial absorber are demonstrated. A very high versatile MA-cell is designed, offering both miniaturized sizes as well as multi-band and/or broad-band behavior, within the RFID UHF-band.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
