Increasing the RFID readability range using wireless power transmission enhancements

In this paper we propose a possible solution to increase the readability range of an inductive coupled based radio frequency identification (RFID) system. The solution is based on the introduction of a resonant printed spiral coil (PSC) in between the reader and the tag in order to enhance the magnetic field and therefore increase the detection range of the RFID reader. The results obtained proved this to be an effective technique, by more than doubling the readable range of the RFID system.
