Smart base station antenna

This paper presents a novel hybrid beam steering scheme for mobile cellular applications. In this scheme, a linear equispaced sensor array of N antenna elements at the base station is used to form a fixed beam pattern in a fixed number of directions covering the cell area. In addition an adaptive pilot beam also is formed by using the same set of antenna elements whose direction can be made to be variable depending upon the traffic requirements. The advantages of the proposed scheme are illustrated by computer simulation results
