Abstract:
A loop antenna includes: a pair of first linear elements, a feed point connected with each of the first linear elements, a first variable impedance element, one end of which is connected with one end of the first linear elements, a second variable impedance element, one end and the other end of which are electrically connected with the other end of the first variable impedance element and the other end of the first linear elements, and a second linear element, one end and the other end of which are electrically connected with the other end of the first variable impedance element and the other end of the first linear elements. A self-resonance coil receives power fed to the feed point of the loop antenna and transmits the received power to a receiving self-resonance coil.
