Abstract :
A reflector antenna configuration is presented that allows beam steering in a wide conical coverage by a two-axes reflector rotation about the focus, while keeping fixed the feed. This approach is able to limit gain loss by high utilization of reflector surface and high reduction of phase errors on the aperture plane. A parametric study has been carried out as function of the antenna geometrical parameters and illumination function.
