High performance lens antenna systems

A cascaded lens system associated with a lens antenna system, comprises:

• a focusing lens configured to receive a collimated beam associated with a source antenna circuit and focus the collimated beam, in order to convert the collimated beam from spatial domain to spatial frequency domain, thereby forming a focused beam associated with the focusing lens;
• and
• a collimation lens configured to couple to the focused beam and collimate a select spatial frequency component associated with the focused beam, thereby forming a real collimated beam.

A lens antenna system, comprising:

• a waveguide array comprising a set of waveguides, wherein each of the set of waveguides is configured to convey electromagnetic waves associated with a communication circuit;
• and
• a lens coupled with the set of waveguides and configured to receive the electromagnetic waves associated with one or more waveguides of the set of waveguides, in order to provide one or more output antenna beams.
