Abstract

Electromagnetic radiation is becoming a major concern worldwide as the use of portable communication devices increases. So, it is essential to utilize safe communication devices. A compact wide-band antenna of size 12 × 8.5 × 0.33 mm3 and a metamaterial array contribution for Specific Absorption Rate (SAR) reduction are proposed in this paper. In this paper, an array structure of split ring resonators, SRR, which have a negative refractive index, is attached to the proposed MSPA to achieve SAR reduction by 89.88% in the 28 GHz range. Furthermore, the proposed antenna maintains other performance characteristics like high gain (7.7 dBi), radiation efficiency (82%), wide bandwidth (0.8 GHz), and fewer losses (-23 dB). However, this consequential antenna has been built on a low-loss Rogers RT 5880 substrate and a full ground-plane structure using CST microwave software.
