Base station antennas are provided. A base station antenna includes a plurality of arrays of radiating elements. The antenna includes a downlink radio frequency (RF) feed network that is configured to filter downlink portions of different frequency bands and that couples the filtered downlink portions of the different frequency bands to the arrays. Moreover, the antenna includes an uplink RF feed network that couples uplink portions of the different frequency bands to the arrays and that is separate from the downlink RF feed network.

Abstract:
Systems and methods for operating an antenna providing a coverage area using beamforming and carrier aggregation techniques. The proposed system aims to optimize the use of carrier aggregation for beamforming systems. The system may include a beamforming module coupled to first array and second arrays of radiating elements, the first array being configured to provide wireless coverage on a first frequency carrier in a first coverage area, and the second array being configured to provide wireless coverage on a second frequency carrier in a second coverage area. The beamforming module may be configured to receive one or more indicators associated with one or more user equipments (UEs) in the coverage area. Based on the one or more indicators, the beamforming module may be configured to dynamically adjust, in the RF domain, at least one of a location of the second coverage area and a size of the second coverage area.
