Claim 0:
1. A twin beam base station antenna, comprising:
a first radio frequency (“RF”) port;
a second RF port;
an array that includes a plurality of columns of first frequency band radiating elements that are configured to form an antenna beam that provides coverage to a predefined area; and
a beamforming network coupled between the first and second RF ports and the array, the beamforming network including a first frequency dependent power divider,
wherein the beamforming network includes a 90° hybrid coupler having a first input coupled to the first RF port, a second input coupled to the second RF port, a first output coupled to the first frequency dependent power divider and a second output coupled to a second frequency dependent power divider, and
wherein a first output of the first frequency dependent power divider is coupled to a first of the first frequency band radiating elements through a 180° phase shifter and a second output of the first frequency dependent power divider is coupled to a second of the first frequency band radiating elements.
