Abstract
Generally, this disclosure provides systems and methods for a modular antenna array using radio frequency (RF) and baseband (BB) beamforming. A system may include a plurality of antenna modules, each of the antenna modules further including an array of antenna elements coupled to an RF beamforming circuit, the RF beamforming circuit to adjust phase shifts associated with the antenna elements to generate an antenna beam associated with the antenna module; and a central beamforming module coupled to each of the antenna modules, the central beamforming module to control the antenna beam associated with each of the antenna modules and to generate signal adjustments relative to each of the antenna modules, wherein the arrays of antenna elements of the antenna modules combine to operate as a composite antenna beamforming array.
