Design of a wireless charging system composited of antenna and circuits in HF band

This work present a systematic design procedure of wireless charging system operating at the frequency 13.56MHz different from the ones used in the current standards. Such a mechanism of power transfer is based on the magnetic induction coupling in terms of electromagnetics. What more important, this work describes both of the design details of loop antenna for magnetic coupling and the circuit of charging. Measurement data are provided in this report.
