Abstract

A wireless power receiving system includes two or more electrically small antenna arms and a common antenna ground. The two or more electrically small antenna arms are connected to the same common antenna ground and are close enough to one another to be strongly coupled. In some embodiments, the two or more electrically small antenna arms are tuned to the same functional frequency so that they load one another to create self-resonance. The wireless power receiving system receives the transmitted wireless power wave emitting from a wireless power transmitter without added lossy matching components.
