Base station clustered adaptive antenna array
First Claim
1. A base station clustered adaptive antenna array comprising:
- a plurality of clusters of antenna elements, wherein each cluster of the plurality is separated from an adjacent cluster of the plurality of clusters by a first predetermined spacing related to receive-mode beamforming, and wherein each cluster comprises a plurality of transmit-receive antenna elements, each transmit-receive antenna element spaced away from an adjacent element of the plurality of elements by a second predetermined spacing related to transmit-mode beamforming, the second predetermined spacing being less than the first predetermined spacing.

Abstract
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.
