Abstract
This paper presents for the first time the wireless power transfer (WPT) system that is fully dependent on the etched slot on the ground plane. At first, the defected ground structure-based resonator with the circuit area of 20-by-20 sq. mm and a rectangular defect was proposed. Then, it was changed to three rectangular slots to achieve resonance at the desired frequency. Subsequently, the resonators with optimized parameters were aptly utilized to design the WPT system that works at 2.4 GHz. The operating frequency complies with the practical medical body area network band and, therefore, can be employed to the biomedical implants. It has been demonstrated that the perfect coupling can be observed at a distance of 10 mm. As a consequence, at this distance the obtained simulation results of WPT show 67% efficiency and the figure of merit of 0.335.
