Strongly coupled resonance magnetic for RFID applications

Wireless power and data transfer (WPDT) through the strongly coupled magnetic resonance (SCMR) method at an RFID frequency is reported. The proposed system consists of four single resonant loops, in contrast to the two resonant loops traditionally used in RFID. The paper addresses SCMR high Q-factor and low bandwidth with a tradeoff to achieve high bandwidth for data transfer comparable to RFID.
