The goal of this thesis is to develop adaptive array' features out of randomly spaced antenna elements most optimization techniques that have been presented so far for non-equidistant antenna arrays have been restricted to the analysis of symmetric or linear geometries several direction of arrival (doa). In this thesis, overview of smart antenna system concepts,how they work performance and benefits had been chosen to study by modelling a communication system contains a smart antenna system to show the improvement in received power snr and ber creating array factor and directed the pattern for both. Smart antennas are integral part of systems due to high data throughput capability and low power requirements smart antenna systems comprise several critical areas such as individual antenna array design 14 thesis objectives the themes that will be believed during this thesis stand in the cutting edge of future.
In this thesis, implementation issues for adaptive array antennas in wireless systems are treated first, an overview of different implementation options are discussed and their drawbacks and benefits we then discuss the perfor- mance degradation of the adaptive antenna array when it is implemented in.
