Efficient Metasurface-Based Wireless Power Transfer System for ISM Band Applications

A new metasurface design for effective wireless power transfer systems is described in this article. A metasurface with an extensive range of phase shift is designed using of hexagon-shaped unit cell. The presented metasurface for 2.4 GHz ISM band applications has been developed and examined. This metasurface offers the ability to transmit any incoming waves as planar waves. To set up a Wireless Power Transfer (WPT) system, two Triangular Microstrip Antennas (TMSAs) operating at 2.39 GHz and 2.42 GHz are analyzed. Based on scattering responses of 3 × 3 array metasurface is proposed to increase the Power Transfer Efficiency (PTE) from 18.17% to 22.95%. This proposed WPT arrangement offers higher PTE performance to make sure that the suitable design.
