Abstract

This paper proposes a novel method of contactless power transfer from a transmitting antenna to a receiving antenna. This method involves electromagnetic coupling of near-field antennas at resonance. However, the exact manner in which method this method can be used to design antennas and circuits has not been clarified. Therefore, this study focuses on defining the exact frequency and efficiency required fore electromagnetic coupling on the basis of the antenna theory, circuit theory, experimental observations, and electromagnetic computations and experiments.
