Shunt Resistance Variation for a Constant Power Supply in UHF RFID Tags
Résumé
In the case of short reader-to-tag distances, shunt resistance diverts current in order to protect the chip but this affects the chip power supply and the delta radar cross section. This paper presents a shunt resistance law variation which keeps a constant power supply in the RFID chip and the impact of this law on the delta radar cross section.
