Abstract: The implementation of smart antenna techniques in advanced wireless systems like 5G Mobile Communications, is expected to have a significant impact on the efficient utilization of the spectrum, the minimization of the cost of establishing new wireless networks, the optimization of service quality, and realization of the transparent operation across multi technology wireless networks. Nevertheless, its success relies on two considerations that have been often overlooked when investigating smart antenna technologies: first, the smart antennas features need to be considered early in the design phase of future systems (top-down compatibility); second, a realistic performance evaluation of smart antenna technique needs to be performed according to the critical parameters associated with future systems requirements (bottom-up feasibility). In this paper an overview of the different types of smart antenna techniques are discussed with an insight to switched beam array and adaptive antenna array elaborated with necessary equations.
