Abstract: A lightweight convex waveguide lens for receiving and/or transmitting electromagnetic signals to/from one and/or multiple signal sources, with the ability to send and receive signals at the same time. This is achieved by assembling wave guiding channels (waveguides) in a structured array (super structure). The waveguides can be partly pre-assembled prior to assembly in the super structure.

Abstract: A waveguide lens antenna (WGLA) with especially wideband characteristics. The geometry of the WGLA is shaped to result in ideal phase shift over a maximum bandwidth. The specific convex shape makes it possible to modulate the phase of all waveguides to generate a plane wave over a much wider frequency band than has earlier been possible. The waveguides are circular symmetric oriented which result in a favourable S-parameter matrix and low cross polar level. The WGLA have scanning properties i.e. provide multiple beams by moving the feeds on the focal plane behind the WGLA.
