Abstract: A phase shifting surface (PSS) array with variable beam angle is introduced in this paper. It operates at Ku band and contains two layers of PSS. The feeding beam can realize 360° scanning in azimuth plane and can be steered up to 78° in the elevation by rotating two PSS synchronously and reversely. PSS array is also fabricated and measured, presenting the well agreement with the designed data. The PSS array has thin profile. It is a new kind of mechanical phased array.
