A front-end antenna system for transmitting and receiving one or more beams and including at least one of a radio frequency (RF) stage, an intermediate frequency (IF) stage, and a digital stage includes one or more beam networks configured to form one or more signal streams over the one or more beams, where each beam network from among the one or more beam networks comprises a beamformer network, a switching network, or a combination thereof. The front-end antenna system includes an array of antennas configured to output each of the beams in a selected spatial region from among a plurality of spatial regions, where one or more antennas from among the array of antennas are multiport antennas. The front-end antenna system includes a plurality of transceivers that electrically couple the array of antennas and the one or more beam networks.
