Abstract: This disclosure relates to an antenna array circuitry for analog beamforming, the antenna array circuitry comprising: a plurality of antenna elements, wherein each antenna element is configured to receive a respective analog signal (r(1,t), r(2,t), r(N,t)), wherein the plurality of antenna elements is adjustable based on a code-word, wherein the code-word comprises respective phase configurations (θp(1), θp(2), θp(N)) of the plurality of antenna elements, wherein the code-word is based on a superposition of a predetermined set of basic code-words, wherein each basic code-word associates with a corresponding sub-beam, wherein a main radiation lobe of the corresponding sub-beam points in a predefined spatial direction.
