  • On the design and implementation of efficient antennas

    HF‐RFID systems, like their LF counterparts, operate based on inductive magnetic coupling, as shown in Figure 1.This sets up a two‐way communication link between an RWD and a passive tag and allows for power transfer to a tag at any position inside the three‐dimensional (3D) interrogation zone of the RWD.
