Beskrivning

Near-field communication (NFC) enables the exchange of information between close devices.The antenna is the indispensable element to transform an electronic device into an NFC system. For both theory and practice, this book presents in detail the design technologies of different antennas. They must meet the NFC ISO 18 092 and 21 481 standards as well as specifications by the NFC Forum for industrial applications, by EMVCo for banking applications and payments, and by CEN for public transport.In a particularly pedagogic way, Antenna Designs for NFC Devices enables designers of communicating object systems and the Internet of Things (IoT) to have access to the mysteries of the design of NFC antennas.
