PLANAR FRACTAL METAMATERIAL RESONATOR AND ENERGY FLUX INCREASING APPARATUS FOR WIRELESS POWER TRANSFER

摘要

A planar fractal metamaterial resonator for wireless power transmission according to an embodiment of the present invention includes a substrate; and a fractal metamaterial resonator formed on the substrate. The fractal metamaterial resonator includes: a fractal split ring resonator (SRR) including an inner conductor and an outer conductor surrounding the inner conductor; a first capacitor in a form of a lumped element formed in a division gap of the inner conductor; and a second capacitor in a form of a lumped element formed in a division gap of the outer conductor. The inner and outer conductors are extended in a fractal structure, respectively, so that the size of the resonator for wireless power transmission resonating at a frequency of 6 MHz adjacent region including 6 MHz, 6.78 MHz, and 13.56 MHz and a frequency of 6 MHz or less may be reduced and the wireless power transmission efficiency may be improved.
