Design and Implementation of a Long-Range RFID Reader for Passive Transponders


This paper presents a long-range RF identification (RFID) reader that has proven to work at up to 5 m with 2-W effective radiated power transmit power at 868 MHz. For the validation, a phase-shift keying backscatter modulator has been implemented, thus complementing the reader to form a complete passive RFID system focused on backscattering communication… (More)
