Adaptive Smart Antenna of Aperiodic Array
In this paper, aperiodic antenna array, where inter-element spacing between antenna elements is non-uniform, is used for beamforming of smart antenna. Here, least mean square (LMS) algorithm is used for adaptive beamforming of smart antenna. Side lobe level (SLL) of antenna radiation beam causes interference for other users and should be reduced in mobile network. Aperiodic array produces lower side lobe level compared to uniform array. The aim of this research work is to investigate nature of adaptive beamforming at different angles using aperiodic array with reduced side lobe level while producing main beam and null towards the desired directions.
