1. An antenna, comprising:
a plurality of radiator columns, each radiator column having a plurality of radiator clusters;
a phase shifter/calibration board having a plurality of input ports and a plurality of phase shifters, each of the plurality of phase shifters is coupled to a corresponding input port via an input trace, each input trace is capacitively coupled to provide a representative power signal to one of a plurality of power dividers, wherein each phase shifter has a plurality of phase shifter output traces having an output port, each of the output ports is coupled to a corresponding radiator cluster of a corresponding radiator column, wherein a subset of the plurality of phase shifter output traces have a designated meander pattern that collectively provides phase matching between the output ports, wherein a first designated meander pattern is adjacent to a second designated meander pattern, wherein the first designated meander pattern and the second designated meander pattern include at least two turns of 90 degrees, and wherein meander turns of the first designated meander pattern are staggered relative to meander turns of the second designated meander pattern, wherein the plurality of power dividers sums the plurality of representative power signals into a single calibration signal; and
a plurality of RF cables, each of the plurality of RF cables couples a given phase shifter output port to its corresponding radiator cluster of its corresponding radiator column, wherein the plurality of RF cables have the same length.
