Perspectives on Huygens’ Metasurfaces for Antenna Beamforming

In this paper some perspectives on Huygens’ metasurfaces for antenna beamforming are described. Both paired, as well as, single metasurface approaches are described for beamshaping of elementary feeding sources in close proximity. Such metasurfaces are capable of controlling the far-zone radiation patterns of these feeding sources, including the shape of the beams and their sidelobe levels.
