Wireless power transfer in near-field communication using a current-controlled multi loops with a loaded capacitance

Wireless power transfer (WPT) in near-field communication (NFC) using current-controlled multi loops with a loaded capacitance is demonstrated in this work. The proposed multi loops antenna design gave low mutual inductance and transfer efficiency required within the operating distance of 1cm to 3cm...
