Abstract
Provided are wireless power transmitting method and apparatus using dual-loop in-phase feeding. The wireless power transmitting apparatus includes a generator configured to generate a Radio Frequency (RF) signal, an amplifier configured to amplify the generated RF signal, a matching circuit configured to be connected to the amplifier to perform impedance matching, a first resonator configured to comprise a first feeding loop connected to the matching circuit and transmit wireless power using a signal provided through the first feeding loop, and a second resonator configured to comprise a second feeding loop connected to the matching circuit and transmit wireless power using a signal provided through the second feeding loop, wherein the first and second feeding loops are formed in a manner that allows magnetic fields respectively generated by the first and second resonators to be excited in the same direction and in phase.
