A 440MHz wireless SAW-based temperature sensor has been proposed on a 41o YX LiNbO3 piezoelectric substrate. Reflective delay line composed of an interdigital transducer (IDT) and several reflectors was used as the sensor element. A high frequency of 440MHz allowed a compact antenna to be designe...
