Abstract

This article presents a passive metasurface reflector (PMR) for signal cover enhancement in sub-6 GHz in an indoor environment. To obtain this, initially, a methodological study to characterize a miniaturized PMR meta-cell with an overall aperture of 0.22

λ_{0}

and a thickness of 0.017

λ_{0}

at 3.3 GHz has been analyzed. Afterward, the reflection characteristics are estimated using the vector synthesis method to predict the far-field scattering beam patterns accurately. Further, the phase gradient profile between consecutive meta-cells of the passive reflector has been generated by altering the coding sequences to tailor the scattered beams in a customized way. Finally, the proposed PMR has been further employed for signal coverage enhancement in blind areas of L-shaped and T-shaped corridors. The simulation results had been validated with the measurement results. It is observed that the proposed PMR achieves 58 dBm and 42 dBm signal enhancement in L and T-shaped corridors, respectively. This research is vivid proof that a PMR is a suitable candidate for 6G FR1 band wireless signal enhancement in an indoor environment due to its low cost and ease of installation on indoor walls.
