Abstract :
We present the main results of a study on the use of anisotropic metasurfaces to realize an antenna radiating a circularly polarized field in an isoflux shaped beam pattern, suitable for LEO satellite application. We summarize the theory on which the design process is founded and provide a numerical validation relevant to an already manufactured antenna prototype. Measurement results will be presented during the oral session.
