Abstract
A beamforming network includes a three-dimensional discrete lens with front and back apertures, each comprising a plurality of discrete elements. Each discrete element of the back aperture is homologous to a respective discrete element of the front aperture. The discrete lens further comprises a plurality of transmission lines connecting respective pairs of homologous discrete elements. The beamforming network can further include a feed array that illuminates the back aperture when the lens is working in transmission, and/or receives signals from the back aperture, when the lens is working in reception. A ratio of a size of the back aperture and a size of the front aperture defines a zooming factor whose value is different from unity, so that angles of emergence of beams of electromagnetic radiation emitted by the front aperture are either tilted towards or away from a center axis compared to angles of incidence on the back aperture.
