Abstract
A single-band metamaterial absorber (MTMA) for Internet-of-Things (IoT) networks, working at 5.8 GHz, is presented. The proposed unit cell with a size of(16\times 16)mm(^{2})has circular and square rings designed on a Rogers RO4350B substrate with a thickness of 1.54 mm. The material properties of the absorber are extracted and used to show the double negative metamaterial behavior. The real and imaginary values of impedance demonstrate the matching of MTMA with the free space. Furthermore, MTMAs with various configurations are designed to validate the impact on the absorption level and operating frequency. All array configurations exhibit nearly perfect,(99.9\%)absorbance. The physical mechanism of MTMA is discussed using an electric field and surface current distributions. The obtained results of the study reveal that the proposed MTMA can be used to charge low-power IoT devices.
