N2 - This paper presents a miniature defected ground structure-based wireless power transfer (WPT) system sup-porting dual-band operation. Firstly, the resonator design is accurately determined to exhibit the optimal surface current distribution. The 15-by-15 sq. mm resonator is further optimized to present the dual-band functionality. Afterward, the resonators are properly coupled at a 10 mm transfer range, resulting in WPT efficiency of 79% at 0.9 GHz and 60.5% at 1.8 GHz. Additionally, the misalignment impact on the WPT performance is evaluated and results demonstrate the robustness within a specific range of horizontal and vertical shifts.
