Sub-coil in reader antenna for HF RFID volume detection improvment

Abstract : This paper proposes a reader antenna, improving the inductive coupling with a small coil whatever its position or orientation against the reader antenna. Sub-coils are inserted and the turn number is optimized in order to improve efficiency of the inductive coupling in the case of HF RFID volume detection in keeping constant the magnetic energy generated by the reader.
