Abstract :
This paper presents a cost effective solution for remote radiofrequency temperature sensing, taking advantage of a Schottky junction nonlinear characteristic and the device integration in a properly designed dual-frequency radiator. Once the proposed integrated active antenna is interrogated with a CW excitation, the level and phase of the third harmonic response signal gives information of the tag temperature to be controlled
