Abstract :
The paper describes theoretical and mainly experimental evaluation of power transfer from a primary to a secondary coil and a transmission of an on-off signal back with an inductive coupling of pair of identical RFID antennas for 125 kHz band. Their function uses principles of RFID systems. The impact of conductive parts around the coils was also examined. The results were intended to design a simple telemetry system which transfers temperature data from a special rotor.
