Abstract: An antenna transceiver architecture for a modular metasurface antenna and method for using the same are disclosed. In some embodiments, the antenna architecture includes a plurality of metasurface antenna tiles, where each metasurface antenna tile of the plurality of metasurface antenna tiles having one or more feed ports individually fed when in operation to support one or more independent beams, and wherein the plurality of metasurface antenna tiles comprise a plurality of sub-arrays of metasurface antenna tiles. In some embodiments, the antenna architecture also includes a plurality of digital back ends (DBEs) coupled to the plurality of metasurface antenna tiles, where each DBE is operable to: adjust time delays of one or more of received signals arriving from metasurface antenna tiles of the one sub-array of metasurface antenna tiles as part of time delay beamforming and combine the received signals in a digital domain to produce one or more beamformed signals, and delay transmit signals fed to the plurality of tiles in the digital domain by adjusting time delays of one or more of the transmit signals as part of time delay beamforming.

Abstract: A combining apparatus for use in a satellite communication system and a method for using the same. In one embodiment, the apparatus comprises: a plurality of antennas that each have a transmit aperture and a receive aperture and are operable to receive correlated signals from a satellite, wherein the receive aperture is operable to receive one of the signals from the satellite and determine its signal quality; a combiner communicably coupled to the plurality of antennas to combine multiple signals received from the plurality of antennas into one signal, wherein the combiner is operable to determine which signals received by the plurality of antennas are to be combined into the one signal based, at least in part, on at least one signal quality metric regarding the signals, the at least one signal quality metric being received from one or more tracking receivers external to the combiner; and a modem communicably coupled to receive the one signal from the combiner, wherein the modem is operable to send information to the plurality of antennas via the combiner as if only a single antenna is coupled to the combiner and the combiner is operable to aggregate information for the modem received from antennas in the plurality of antennas as if one single antenna provided the information to the combiner.
