Abstract

Disclosed is an electronic device including a resonator that generates an induced current by electromagnetic coupling. The resonator includes a first conductor, a plurality of second conductors, a one end of each of the second conductors being electrically coupled to a first point of the first conductor, and an other end of each of the second conductors being electrically coupled to a second point of the first conductor, and at least one impedance load connected with the second conductors in series or in parallel. Thus, the resonator may generate current through the first and second conductors.
