摘要

提出了一种基于重叠缺陷接地结构的小型双频无线电力传输系统。一个频带用于供电,另一个频带用于数据传输。所提出的缺陷地面结构可以引导两个不同的谐振频率。因此,与文献[9]相比,制备的WPT器件在不改变其他性能的情况下,尺寸缩小了近50%。制作的器件尺寸为15mm ×15 mm。在WPT距离为12.5mm时,在0.45 GHz和0.95 GHz频段的实测效率分别为71%和73%。

Compact Dual-Band Wireless Power Transfer Using Overlapped Single Loop Defected Ground Structure
This paper presents a compact dual-band wireless power transfer (WPT) system using overlapped defected ground structure for biomedical applications. One band for power and another for data transfer. The proposed defected ground structure can channel two distinct resonant frequencies. As a result, the fabricated WPT device has almost 50% reduction in the size without changing other performances compared to ref. [9]. The fabricated device is 15 mm ×15 mm. The measured efficiency is 71% and 73%, respectively at 0.45 GHz and 0.95 GHz at WPT distance of 12.5mm.
