  1. 1. Multiplexing NFC Antennas : An evaluation of the technique and its limitations

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datavetenskap

    Författare :Viktor Gustafsson; Per Ottosson; [2023]
    Nyckelord :AAT; BER; DSR; Impedance; Multiplexer; NFC; Wireless Technology;

    Sammanfattning : Introduction This study aims to investigate the possibility of driving multiple NFC antennas with a single NFC-controller by using a multiplexer. An artifact was developed and experiments were conducted in order to evaluate the design choice and in addition, to observe the impact of a multiplexer in an NFC system with respect to the number of successful tag detections, bit error rate (BER), the utilization of automatic antenna tuning (AAT) and the physical distance to the NFC tag.
