Abstract
In this paper a reflectarray design for a membrane spaceborne antenna to be used in a typical SAR mission is presented. An L-Band reflectarray, with a dimension of 10 by 6 meters on Kapton foil substrate, has been designed. To evaluate the tolerance to the membrane deformations, a model for the surface wrinkles and sag is developed and their effects on the antenna performance are analyzed. Finally, a full-wave numerical analysis has been performed and the result are presented.
