Abstract
Unique photonic beamformer and remoting head for phased array antennas in broadcast mode wireless communications is proposed that enables flexible antenna array upgrades via software and flexible front-head attachments. This array controller capability leads to user defined changes in number of antenna elements, antenna aperture shape, antenna aperture size and antenna carrier frequency. Experimental proof-of-concept flexible beamforming results are described that generate the desired set of phase shifted radio frequency signals. The flexible beamformer is particularly suited for generating multiple broadcast antenna beams.
