1. A base station antenna, comprising:
first through fourth radio frequency (“RF”) ports;
a plurality of radiating elements that each includes a first radiator, a second radiator, a third radiator and a fourth radiator that are arranged in a box or loop configuration;
a first combiner having a first input that is coupled to the first RF port, a second input that is coupled to the second RF port, a first output that is coupled to the first radiator of a first of the radiating elements and a second output that is coupled to the second radiator of the first of the radiating elements; and
a second combiner having a first input that is coupled to the third RF port, a second input that is coupled to the fourth RF port, a first output that is coupled to the third radiator of the first of the radiating elements and a second output that is coupled to the fourth radiator of the first of the radiating elements,
wherein the first through fourth RF ports are coupled to a single radio and operate in a same frequency band.
