Abstract

Surface acoustic wave (SAW) RFID tags are promising devices for the identification of work pieces in an industrial environment. Their practicality was tested using different types of ID tags operating in the 2.45 GHz ISM band with a code volume of 2²⁰- 2³⁶. The tags were produced to withstand temperatures up to 350degC. The performance was assessed by measuring the probability of identification as a function of distance. A reading range of several meters was demonstrated, showing that the tags are appropriate for industrial processing lines. Readout of two tags within one antenna beam (anticollision) was demonstrated.
