Parameter analysis and reader architectures for broadband 13.56 MHz RFID systems

The underlying paper deals with HF RFID systems and the influences of different parameters on the entire system and the effects for ‘very high data rates’ (VHD) up to 6.7 Mbit/s. After a short introduction to 13.56 MHz RFID systems, characteristic parameters such as Signal to Carrier Ratio, quality factor, bandwidth and energy are pointed out in the context of VHD. Based on that different reader concepts will be evaluated and the implementation of a testplatform will be shown. Finally dynamic effects of the system will be explained, which have to be taken into account for VHD transmissions.
