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.

A multibeam antenna and method of using the same are described. In one embodiment, the antenna comprises an aperture having a plurality of radio-frequency (RF) radiating antenna elements. The RF radiating antenna elements generate a plurality of beams simultaneously in different directions in response to a first modulation pattern for holographic beamforming applied to the plurality of RF radiating antenna elements to establish all beams of the plurality of beams such that antenna elements of the plurality of RF radiating antenna elements contribute to all beams in the plurality of beams concurrently. The antenna also includes a controller coupled to the aperture to generate the first modulation pattern.

Antennas such as flat panel, leaky wave antennas with directional coupler feeds and waveguides are disclosed. In one example, an antenna includes a surface having antenna elements, a guided wave transmission line, and a coupling surface. The guided wave transmission line provides a guided feed wave. The coupling surface is between and separates the guided wave transmission line and the surface having antenna elements. The coupling surface controls coupling of the guided feed wave to the antenna elements. The coupling surface can also spatially filter the guided feed wave to provide a more uniform power density for the antenna elements. The guided feed wave can be a high power density electromagnetic wave or a density radially decaying electromagnetic wave.
