In this paper, we propose a highly efficient multi-directional beam steering (MDBS) metasurface for the 28 GHz mm-Wave band, designed using a high periodicity supercell (5.76λ) and surface impedance modulation (SIM). The MDBS metasurface follows the generalized phase law of reflection and achieves eleven distinct beam steering directions with high reflection efficiencies of 98.26% for TE mode and 93.04% for TM mode. The design is polarization-independent and functions for various incident angles simultaneously, making it a robust solution for extending 5G coverage in non-line-of-sight (NLoS) scenarios. The performance of the proposed metasurface is validated through both full-wave simulations and experimental measurements, demonstrating its capability as an efficient, compact, and scalable solution for next-generation mm-Wave communication systems.
