Abstract: 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.
