Abstract
In this article, a new wireless power transfer (WPT) design is proposed for improving the efficient of system. The suggested system contains two spiral defected ground structure (DGS) resonators coupled back-to-back. The spiral DGS alone acts as band stop filter (BSF), and when the two resonators are coupled back-to-back, a BSF is emerged leading to WPT system. The DGS resonators are loaded through chip capacitors for miniaturization. The proposed structures are fabricated and tested. The proposed system has a highest efficiency of 97.7% at a transmission distance of 10 mm which is suitable for biomedical applications. Both simulated and experimental results are in good concurrence.
