Adaptive/Smart antenna arrays allowed an antenna to steer the beam to any direction of interest (DOI) while simultaneously nulling interfering signals. In this paper an approach based on Least Mean Square (LMS) is incorporated to minimize the SLL and MSE of adaptive antenna arrays by varying the interelement spacing in between 0.5? to 1.0? with DAOA~10 deg. and IAOA~70 deg. LMS is a one of the most efficient gradient based approach of steepest decent that makes correction to the weight vector to minimize the MSE. After comparing with previous results of uniformly spaced elements with our proposed approach, superiority of our proposed approach is established.
