2D Beam-steering with non-symmetrical beam using non-symmetrical integrated lens antenna

This article presents an integrated lens antenna design that allows two-dimensional beam-steering with a non-symmetrical beam. The lens design is based on a traditional integrated lens concept. It is shown that, with a simple modification, the beam-shape can be changed without compromising the beam-steering properties. The limitations and properties of the proposed design are studied. Beam-steering properties of two lens designs are tested with radiation pattern measurements at 77 GHz.
