Abstract :
This contribution evaluates backscatter radio frequency identification (RFID) systems on the body of a human being at 900MHz and 2.45GHz. The systems are composed of different on-body antennas. Custom-built monopole antennas act as a best-case reference, while less efficient patch antennas are used to give an insight in practical system implementations. The evaluation of these systems is based on channel transfer function measurements, which allows to deduce outage probabilities of the RFID systems. These probabilities give an insight in the system performance in forward and backward link and help to identify the limitations in the backscatter communication to realize a reliable system.
