Abstract: The present invention relates to a wireless power transceiving system which includes: a TX resonator for transmitting power wirelessly through resonance; and an RX resonator installed at a certain distance from the TX resonator for receiving the transmitted power wirelessly. The impedance of the TX resonator (Ztx) and the impedance of the RX resonator (Zrx) are determined to make the value of an S parameter measured between the RX resonator and the TX resonator have a preset value. The present invention is able to define the efficiency of the TX resonator and the RX resonator, transmitting power and receiving power depending on the TX impedance (Ztx) and the RX impedance (Zrx). By determining the transmitting efficiency of a wireless power transmitting resonator using the S parameter, it is possible to develop a wireless power transmitting resonator with power transmitting efficiency higher than a certain value and manage the efficiency of the resonator regardless of structure or material.
