Abstract
This work focuses on 13.56MHz NFC antennaas that will satisfy the operational requirement in horizontal orientations. The wavelength of 13.56MHz systems corresponds to about 22 m. However, the antenna size is a small fraction of that in size and the operating distance is in the range of the reader antenna's diameter. Hence, the interaction between the reader and the ring happens in the near field of the interrogator. This leads to the fact, that the fundamental working principle can be described by a transformer, the capacitive or inductive coupling between the reader and the ring. In order to achieve a good coupling, the structure is made of different coils aligned together according to the current flow to avoid the disturbance of the induced magnetic field. In short, the coupling and the magnetic field distributions between the two components, the reader and the ring are presented.
