A mm-Wave RFID system based on the EPC-Gen2 protocol

The importance of radio frequency identification (RFID) is expressed by the vast amount of commercial applications using this approach. Worldwide, billions of the RFID systems are operated in the HF (13.56 MHz) and UHF (868 and 915 MHz) frequency range. These RFID implementations suffer from rather large antennas required for a reliable and efficient operation. Increasing the operating frequency overcomes this physical constraint.
