1. A base station antenna, comprising:
a first radio frequency (“RF”) port;
a second RF port;
a third RF port;
a first array of radiating elements that includes a first radiating element, wherein the first radiating element includes first and second radiators each having a first polarization direction, and the first radiator is fed solely by the first RF port;
a second array of radiating elements that includes a second radiating element, wherein the second radiating element includes a third radiator having the first polarization direction so that the second radiator and the third radiator are each fed solely by the second RF port; and
a first power divider having a first input that is coupled to the second RF port, and first and second outputs that are respectively coupled to the second and third radiators.
 
15. A base station antenna, comprising:
a first radio frequency (“RF”) port;
a second RF port;
a first array of radiating elements that includes a first radiating element having first and second radiators that each have a first polarization direction and third and fourth radiators that each have a second polarization direction; and
a second array of radiating elements that includes a second radiating element, the second radiating element comprising a cross-dipole radiating element having a fifth radiator having the first polarization direction and a sixth radiator having the second polarization direction,
wherein the first and second radiators are coupled to the first RF port and not to the second RF port the third radiator and the sixth radiator are coupled to the second RF port and not to the first RF port.
 
19. A base station antenna, comprising:
a first radio frequency (“RF”) port;
a second RF port;
a third RF port;
a first column of radiating elements that includes a first radiating element having first through fourth radiators and a third radiating element that is coupled to the second RF port;
a second column of radiating elements that includes a second radiating element, the second radiating element comprising a cross-dipole radiating element having a first dipole radiator and a second dipole radiator that is coupled to the third RF port; and
a three port power divider having an input coupled to the first RF port, a first output that is coupled to the first radiator of the first radiating element and a second output that is coupled to the first dipole radiator of the second radiating element.
