Abstract

A miniaturized design of metamaterial-inspired split-ring-resonators- (SRRs-) loaded loop structure is proposed for enhanced wireless power transmission (WPT) applications. The magneto-inductive coupling between transmitting and receiving loops is enhanced by respectively embedding a pair of SRRs inside the loops. The sizes of both the loop and SRRs are reduced by capacitive loading. The fabricated 13.56-MHz prototype design is very compact and measures only 49 mm × 49 mm. Though small in size, the impedance matching is also achieved by the capacitive loading. The proposed structure exhibits a satisfactory level of power transmission efficiency (PTE) of about 58%, comparable to the 64.2% PTE obtained in [1] with diameter of 80 mm.
