Base station clustered adaptive antenna array

摘要

A base station clustered adaptive antenna array includes a plurality of clusters of antenna elements. Each cluster is spaced away from an adjacent cluster by a first predetermined spacing related to receive-mode beamforming and includes a plurality of transmit-receive antenna elements. Each element within the cluster is spaced away from an adjacent element by a second predetermined spacing related to transmit-mode beamforming. In order to reduce the visual impact of the antenna array, each cluster is included within a single exterior housing or radome. A medial receive-only antenna element may be provided between adjacent clusters to enhance beamforming for reverse link reception.
