MIMO based chipless RFID system

Chipless RFID systems are perhaps the most eligible candidate for catering the demand of low-cost multiple item tagging in future. However, the absence of a microchip in chipless tags limits the processing capabilities hence the RFID reader has to improvise most of the processing. In the mean time researchers have focused on applying MIMO antenna technology and decoding techniques in chipped RFID systems to utilize its unique spatial multiplexing capability and high diversity gains. However, applying the same techniques in chipless RFID systems is still a challenge due to less processing power available at the tag. This paper proposes a novel MIMO based multi-resonator chipless RFID systems and its validity is verified using Matlab simulations.
