Abstract

A Beam shaping flat lens (BSFL) has been designed to shape a primary beam of a patch antenna into a desired pattern of a flat-top beam. Magnitude directivity functions of primary and desired beams are applied to calculate the required phase gradient profile using equation of the Generalized law of refraction (GLR). Resultant phase profile is practically implemented using a multilayer phase shift structures (PSS) radially distributed along the surface of the lens. Fifteen unique PSSs are arranged to create a flat lens of dimensions 75 x 75 x 3.35 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> with F/D ratio of 0.5 at 30 GHz. A flat-top beam of 60º beamwidth with ripple level of ± 1dB is achieved with good transmission properties.
