Smart antenna systems is one of the most rapidly developing areas of communication. With effective Direction Of Arrival (DOA) and Beam forming techniques Smart Antenna Systems prove to be most efficient in terms of quality of signals in wireless communication. In this paper a brief overview of Smart Antenna along with a survey on high resolution direction of arrival estimation algorithms for array antenna systems is presented and compared for different parameters. It can help one understand the effectiveness of the DOA algorithms over others under certain parametric conditions.
