We present the RF model and correlation with measurements in K band (18.7 GHz) of a 5.1 m diameter deployable reflector antenna in lightweight mesh technology. The RF model includes the manufactured surface shape, electrical properties of the lightweight mesh, a designed and non-circular rim as well as feed tower and truss. Good agreement between main beam shape as well as sidelobe and grating lobe positions between measured and predicted patterns is found.
