dc.description.abstract | This letter presents efficient near-field beamforming using two-layer planar loop array resonator for magnetic resonance wireless power transfer (MR WPT). This two-layer structure provides enhanced power transfer efficiency (PTE) of two important functions by adjusting the lumped capacitance of each loop: beamforming and ability of spatial position freedom and spatial alignment freedom with the receiver. The optimal capacitance of each loop can be found using a genetic algorithm (GA). The three types of two-layer loop arrays such as 1x1 and 4x4, 2x2 and 4x4, and 4x4 and 4x4 are designed at an operating frequency of 6.78 MHz. Overall, these two-layer loop arrays improve the overall simulated PTE compared with that of the 4 x 4 single-layer loop array. Especially, the two-layer loop array of 2 x 2 and 4x4 provides the most improved beamforming performance and spatial freedom among them. The measured PTE also increases by about 10% compared with that of the 4 x 4 single-layer loop array. | - |
