A Novel Efficient Design for Wireless Power Transfer Employing T-Slot Defected Ground Structure

Abstract

This work suggests a novel model for short-range wireless power transfer (WPT) technology. The construction achieves strong power transmission using coupled resonators composed of a T-slot defected ground structure (DGS) and incorporated with two chip capacitors. The design works at 1.05 GHz and attains power transfer efficiency of 97.8 % at a distance of 10 mm with a size of 25 mm × 25 mm. Good concurrence between the simulated, theoretical, and measured data has been obtained.
