Abstract We designed and manufactured a rechargeable battery charger that can be charged quickly by sending power wirelessly to smart devices with wireless charging capability. For this purpose, the impedance matching of the magnetic induction type antenna and the design of the circuit module capable of highly efficient transmission and reception are applied to the integrated antenna module, which makes it compact for portable use. Also, the maximum power value and power detection technique for transmission efficiency optimization were applied to design the structure considering the convenient structure and design.
