Abstract
A magnetic resonant coil system for enhancement of wireless power transfer efficiency of NFC devices was proposed. The NFC system consists of resonant coils arrange between source coil and device coil. The effects of resonant coil was measured using a 13.56MHz RFID reader and tag system and simulated by 3D RF simulator. The measurement results from RFID reader and tag show that the maximum distance of signal transmission is increased by 96.72% and received voltage of RFID tag is grew by 17.95% thanks to the magnetic resonant coils.
