Abstract
Rapidly and Emerging trends of mobile communication and ever growing demand of mobile users created the need for new technologies that could satisfy this need under limited bandwidth provided to telecom companies .Smart antenna systems are one of these technologies which could provide directed radiation pattern towards desired direction , better capacity and reduce interference .which affects used bandwidth antennas are not smart; it is the overall system that tell them what to do is smart. Smart antenna Systems had two main parts Beam forming, which the radiation pattern is shaped and directed through it, and Direction of Arrival (DOA) algorithm that detects the user‘s location and uses it to direct the pattern. The antennas in the array interact constructively in the desired direction and destructively in other directions. 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 Linear and Planar Arrays. Generate the Signal, modulation and transmit it through channel expose with added Noise. Simulation and resultsobtained Using MATLAB toindicated Preference of using smart antenna over conventional single element antennaand it Provide a way better performance.
