Claim 10:
11. An antenna array, comprising:
antenna elements comprising waveguide structures arranged into concentric sets about a central axis, the waveguide structures each comprising apertures at first longitudinal ends and feed points at second longitudinal ends;
wherein each set among the concentric sets are sized to emit or receive, at corresponding apertures in accordance with a beamforming configuration, radio frequency signals having a frequency range specific to that set;
wherein the beamforming configuration comprises a first set of the antenna elements configured to transmit RF energy using at least one among a 4:2 and 8:2 first beamforming configuration, and a second set of the antenna elements configured to receive RF energy using at least one among a 4:2 and 8:2 second beamforming configuration.
