Recently, the most important technology used in 4G and 5G mobile communications is adaptive smart antenna. The smart antenna is a retrodirective transmit and receive radio signal system. The design of smart antenna of λ/2 dipole array using sign least mean square (SLMS) and variable step-size SLMS (VS-SLMS) algorithms is reported in this paper along with comparative results between these two algorithms regarding adaptive beam formation in a cellular network. VS-SLMS algorithm can produce lower side lobe level (SLL) compared to SLMS algorithm, and also, the convergence of VS-SLMS algorithm is better.
