Abstract
A hybrid antenna including a dielectric lens-antenna in the shape of an extended hemispherical dielectric lens than is operated in the diffraction limited regime. The dielectric lens-antenna is fed by a planar-structure antenna. The planar antenna is mounted on the flat side of the dielectric lens-antenna, using it as a substrate. An optimum extension distance is found experimentally and numerically for which excellent beam patterns and simultaneously high aperture efficiencies can be achieved. The hybrid antenna is diffraction limited, space efficient in an array due to its high aperture efficiency, and is easily mass produced, thus being well suited for focal place receiver arrays.
