(a) Normalized magnetic field generated by the commercial transmission antenna with dimensions (318 mm × 338 mm × 30 mm). (b) Magnetic field strength along the line (0,0,Z) as a function of the distance Z normal to the transmission antenna for different input power Pin (1, 4, and 8 W). (c) Scattering parameters for the electromagnetic energy transfer between the coils when the NFC coil is located at the centre of the transmission antenna (0,0,0). (d) Simulated power in the NFC coil at different distance Z normal to the primary antenna with Pin = 8 W.
