Abstract :
To evaluate radiation loss and conductor loss which are the cause of deterioration in the wireless electric power transmission, a calculation method of a transmission electric power, a radiated power, and a conductor loss as a ratio to the input electric power is proposed. The dependency of these ratios on the resistance and the reactance of the receiving circuit are clarified for the short distance wireless electric power transmission between small dipoles, and the method to improve the transmitting efficiency is investigated.
