Executive Summary

This paper presents a Dual Beam Array (DBA) for higher-order sectorization of a cellular site. This technique provides a means of cost-effective boosting network capacity without the use of additional frequency spectrum. The DBA comprises of a multi-column array and a beam forming circuit, which produces two overlapping beams with adjustable beam patterns. The proposed antenna is an adjustable cylindrical sector array, composed of three separate linear array columns. This structure allows for the formation of two overlapping beams with amplitude and phase excitations which can be implemented using a compact and low loss circuit.
