1. An apparatus, comprising:
an antenna array comprising a plurality of antenna elements formed by waveguide structures embedded within a substrate and positioned about a longitudinal axis of the substrate to form at least two concentric ring arrangements of antenna elements;
feed elements coupled to the waveguide structures on an end opposite of apertures of the waveguide structures, and configured to couple radio frequency (RF) energy for the antenna array in accordance with a beamforming configuration;
wherein the beamforming configuration comprises a first ring 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 ring of the antenna elements configured to receive RF energy using at least one among a 4:2 and 8:2 second beamforming configuration.
