Abstract :
Far-field radiation from coupled-resonant wireless power transfer antenna is discussed. When using a switching power supply to improve power transmission efficiency, antenna input voltage includes many harmonics. Since coupled-resonant wireless power transfer antenna is an electrically small antenna for fundamental frequency, this antenna has high radiation efficiency for harmonics frequency. In this report, far-field radiation for fundamental and harmonics frequency is discussed.
