Abstract: A low profile and broadband sequential rotation array of circularly-polarized metasurface antenna elements at Ka-band is proposed in this paper. The antenna element includes a ...

Abstract: A novel approach by utilizing the fast mechanical rotation of arrays has been proposed for low sidelobe levels by integrating the rotational time-varying radiation pattern in a short time.
