Abstract :
This paper introduces new transponder-design concepts which aim to enhance the working range in passive HF RFID systems. Sideband theory, system architecture, chip design, verification and interdependencies will be discussed. Test- chip measurements show a decrease of 40% in field strength requirements for operation. The working range enhancement compared to products currently available on the market is at least 20% depending on the reader unit setup.
