Abstract :
This paper presents a new passive wireless sensor platform on the basis of the intermodulation communication principle. The platform utilizes a quartz crystal or other mechanical resonator and it enables a narrow bandwidth and ID-code to the sensor. A previously presented theory for predicting the intermodulation response of the sensor is elaborated and verified by a simulation. The concept is experimentally demonstrated at 1.2 GHz.
