Abstract

The present invention relates to an apparatus supplying power wirelessly and which prevents harmonic radiation. The undesirable occurrence of harmonic radiation in an apparatus supplying power wirelessly can be reduced so as to solve electromagnetic interference problems. A harmonic antenna for absorbing and canceling harmonic radiation is added to the signal reception antenna for transmitting power, thereby blocking the harmonics generated by a non-linear device with no loss of reception power so as to decrease electromagnetic interference and increase efficiency.
