Beamforming is a vital component in space division multiple access (SDMA) and currently employed sectorial beamforming that radiates throughout sector(s) is not sufficient for next generation communication systems. Hence, massive Multiple-Input Multiple-Output (MIMO) having large number of antenna elements is employed in 5G and beyond communication systems that has capability to provide practically realizable SDMA. However, such setups are not economical as large number of antenna elements are employed. Present disclosure provides systems and methods that implement electro-mechanical beam tilting based approach, that uses a single antenna element coupled with a meta-surface mounted on top which provides a directional beam leading to an improvement in signal to noise ratio (SNR). The meta-surface-based beamforming architecture of the system provides an improved bit error rate (BER) and spectral efficiency (SE) with huge reduction in number of antenna elements without using phase-shifter.
