Characterization of Harmonic Signals Backscattered by Conventional UHF RFID Tags
This paper presents the impact of the non-linear behavior of UHF RFID chips on the backscatter radiated signals by commercial RFID tags. In particular we analyze and quantify the power level of the third harmonic backscattered signals by the tags. The study shows the presence of a third harmonic signal for all tested UHF RFID tags, including tags equipped with the most recent chips. The measurement shows that the level of the radiated third harmonic signals is strong enough to be detected and potentially processed. In addition, if the radiated power of the third harmonic signal varies from one tag to another having the same chip and different antennas, this variation is minor considering identical tags.
