This paper describes the design, fabrication and characterization of a 42 GHz compact lens antenna integrated in a backhaul terminal radome. The proposed lens concept relies on the use of hybrid design that mixes a single refractive bulk zone and dielectric structured zones. This allows overcoming usual Fresnel lens efficiency limitations occurring in compact configurations. The antenna is composed of a small microstrip patch array feeder and of a radome integrated square lens. Radome was manufactured using an additive manufacturing technique. The fabricated antenna was fully characterized and exhibit characteristics suitable for point-to-point backhaul applications.
