Analysis and synthesis of supershaped dielectric lens antennas

IET Microwaves, Antennas and Propagation, 2015
: A novel class of supershaped dielectric lens antennas, whose geometry is described by the three-dimensional (3D) Gielis formula, is introduced and analysed. To this end, a hybrid modelling approach based on geometrical and physical optics is adopted in

Scan-optimized Integrated Lens Antennas

27th European Microwave Conference and Exhibition, 1997
In this paper the scan properties of integrated lens antennas with a quarter-wavelength matching layer are analyzed. For beam scanning on and within a cone, optimum feed positions are determined. It appears that for beam scanning on a cone the elliptical lens is the best choice if a small scan angle is required while the extended hemispherical lens ...
