Abstract

This article presents a compact, wide-angle, polarization-insensitive metamaterial harvester that can efciently harvest electromagnetic (EM) energy in the S, C, X, and Ku bands. The harvester’s unit cell consists of a split ring resonator, two strip lines, and two split strip lines, giving it a total size of (10 × 10) mm2 . Each split gap is flled with a 50 Ω resistive load. The input impedance of the harvester is precisely designed to match that of free space, allowing for efcient absorption of EM power and appropriate redirection towards the resistive loads. The harvester’s performance is also evaluated for various polarization and incident angles, considering the Transverse Electric and Transverse Magnetic modes. The simulation results reveal that the proposed harvester exhibits a notably greater conversion efciency of around> 95%. The simulation outcomes were carefully validated through experimental tests conducted in an anechoic chamber using a 3× 3 cell array of the proposed design. This ensured the accuracy and reliability of the results. The strong correlation between the experimental data and the full-wave simulations strongly supports the efectiveness of the proposed harvester. Therefore, the demonstrated efciency and compact size make it a perfect ft for energy harvesting systems in wireless sensor networks.
