A Study on Spatial Correlation Characteristic of Array Antenna for Multi Antenna System

Channel Modeling for Fifth Generation Cellular Networks and Wireless Sensor Networks

“…For mobile terminals, ignoring the mutual coupling, antenna spacing of about λ/2 is suggested, as they are usually surrounded by scatterers providing a rich multipath environment. For elevated base stations, however, an inter-element separation of more than 10λ may be required to maintain a similar correlation coefficient [10]- [12].…”
