One of the most rapidly developing areas of communications is Smart Antenna systems. This paper mainly concentrates on use of smart antennas in mobile communications that enhances the capabilities of the mobile and cellular system such a faster bit rate, multi- use interference, space division multiplexing (SDMA), increase in range, Multi path Mitigation and reduction of errors due to multi path fading and with one great advantage that is a very high security. The signal that is been transmitted by a smart antenna cannot be tracked or received by any other antenna thus ensuring a very high security of the data transmitted. This paper also deals the required algorithms that are needed for the beam forming in the antenna patterns.
