Figure 1

Sketch of the reflectarray mounted on a small satellite, including the diagram of the antenna optics under consideration. The reflectarray is elliptical and comprised of microstrip patches of variable size. The feed horn is placed in the XZ plane of the reflectarray coordinate system \((\hat{x}_r, \hat{y}_r, \hat{z}_r)\) and generates an incident field on its surface which is reflected back by the reflectarray.
