1. An antenna for use in a Massive MIMO (Multiple Input Multiple Output), comprising:
a gradient index sphere having a diameter; and
a plurality of radiators disposed on the gradient index sphere along an azimuthal plane and at an angular spacing, each of the plurality of radiators having a corresponding beamwidth,
wherein the diameter and the angular spacing are configured whereby the corresponding beamwidth of each of the plurality of radiators is substantially uniform and whereby the corresponding beamwidth is substantially equal to the angular spacing, wherein the diameter is 500 mm, and the angular spacing is 10 degrees, and wherein each of the plurality of radiators is configured to radiate in a C-Band.
