Parametric study of a double shifted “Bull's eye” structure at V-band for beamforming

We study a “Bull's eye” antenna with double shifted rings structure at 60 GHz. We conducted a parametric study of a symmetric configuration, and we predict that two lobes can be steered to opposite sides of the normal by up to 18.6°. This is a similar range to a single shifted “Bull's eye” antenna that we studied earlier, except the double structure produces two lobes. These two lobes can be created without sacrificing the efficiency or directivity relative to a single “Bull's eye” antenna.
