Abstract: An antenna apparatus comprising at least one antenna array configured to produce a beam to facilitate wireless communication with at least one other antenna apparatus is described, in which the beam can be electronically steered in an associated beamforming plane by beamforming circuitry. The at least one antenna array has an associated antenna array plane, and an antenna array rotation mechanism is configured to rotate each antenna array in its associated antenna array plane to cause its beamforming plane to rotate. Methods for operating such an antenna apparatus, and for deploying an antenna apparatus in a wireless communication network, are also described.
