A System Study for RFID

RFID transponders that are based on polymer integrated circuits have the potential to be produce d at high volume and low cost, due to the usage of soluble polymer semiconducting materials in printing processes. In this work, the concept of designing and simulating a passive polymer RFID transponder is presented. Models of the component soft he overall RFID-system, consisting of the reader and the polymer transponder, are derived. Simulation and measurement match well and show that inductive coupled polymer transponders can be operated at the standardized frequency of 13.56 MHz with a read range of at east 5cm. The read range is basically limited by the antenna design and the polymer rectifier. With the realized system simulation, the information transmission from the transponder to the reader can be simulated for various antenna designs, coding schemes and perturbations due to motion of the transponder.
