Aperiodic and non-planar array of electromagnetic scatterers, and reflectarray antenna comprising the same

The application discloses a one or two dimensional array of electromagnetic scatterers n scatterers (ED), whereby the aforementioned scatterers (ED) are arranged aperiodically on a curved line or surface (S). Further, the application describes a reflectarray antenna comprising at least one such array of electromagnetic scatters (ED) and at least one receiving and / or transmitting feed (F), cooperating with said array to generate an antenna beam A method for designingand manufacturing sais array and said antenna is explained. The method optimizes in a several stages all degrees of freedom in order improve the performance of reflectarrays, increase the flexibility thereof and/or the conformity thereof with design specifications (radio pattern) and / or allowing said specifications to be satisfied with a smaller number of scatters.
