Abstract :
Near Field Communication (NFC) technology evolved from a non-contact radio frequency identification (RFID) technology and intercommunication technology. Sensor reader, contactless card and peer to peer features integrate to a single chip. This chip could communicate with compatible devices by the identification and data exchange at a short distance. The technology was a simple merger of RFID technology and network technology at first, but it has evolved into a short-range wireless communications technology, which develops very quickly. This paper introduces the concept and characteristics of NFC technology first. Then, starting from the antenna coil used by NFC technology, this paper accomplished the theoretical analysis, Matlab simulation, HFSS and ADS2009 joint simulation respectively, and improved design an antenna impedance matching approach.
