Abstract :
This paper presents the use of surface acoustic wave resonators (SAWRs) in passive remote identification and sensor system in the European 433.92 MHz ISM-band. The identification device consists of a SAWRs parallel circuitry and is connected via matching network to the Tx/Rx antenna. The narrowband interrogation was the main criteria for the device development. An integrated sensor function was added by sensitive SAWR. Depending on application a direct peak frequency change or a differential frequency method are feasible. Theoretical and experimental results of the SAW resonator identification tag (RESTAG) with 5 and 12 bits respectively are presented and discussed. The device was developed and optimized for the identification and temperature measurement.
