Abstract
This paper presents a new wideband foldable orbital angular momentum (OAM) reflectarray antenna. The antenna consists of three parts: The first part is the upper linearly polarized grid (LPG), which can transmit one linearly polarized wave through its orthogonal linearly polarized wave at the same time. The second part is the lower dual-polarized OAM reflectarray, which can generate high gain OAM vortex electromagnetic wave. It plays the role of polarization torsion on the linearly polarized wave emitted by the feed-source at the same time, so as to realize the folding performance of the ref-lectarray, which reduces the longitudinal profile of the reflectarray antenna. The third part is the wi-倪涛，陈官韬
