  • Patent number: 11329697
    Abstract: The present invention broadly relates to a multi-layer electromagnetic coupler arrangement, for encoding an RFID tag, suitable for being used in a printing device. The coupler arrangement employs a differential transmission line loop, as a coupling element arranged on a top surface layer of the multi-layer arrangement, which is arranged close to a metallic ground plane layer for shielding on the side opposite the top surface. Coupling is achieved by inductive coupling in the reactive near field and based on the fact that each RFID tag comprises a current loop, itself. The differential property of the transmission line loop is achieved by feeding the terminals of the loop with signal parts having a phase shift of 180° with respect to each other. The feeding components are arranged on the opposite side of the ground plane with respect to the top surface layer comprising the current loop.
