Direction-of-arrival estimation takes a great researching interest in such tasks as direction-finding, sonars and wireless communications and is used to determine radio sources. The antenna arrays forms used have been studied like uniform linear arrays, rectangular and circular arrays. The main advantage of linear arrays for direction-findings is that has the narrow beam of the radiation pattern, but the scan is only capable for azimuth space. The application demanding as azimuth as elevation scanning make use of planar arrays. In present the papers which devote to comparable research of direction-of-arrival estimation via planar arrays, consider only one or two types. The main task of this paper is to begin deeply comparing the planar arrays for DOA estimation for the azimuth and elevation scanning.
