An improved method is presented to account for blockage effects in the analysis of reflector antennas. Commonly this is done by introducing shadows on the reflector surface according to the location of the obstacles when performing the physical optics (PO) integration. By using physical optics blocka...
Faceted reflectors are widely utilised in the application of satellite deployable antennas. The sensitivity analysis with respect to surface deformation is an essential part in the error evaluation for distorted reflector antennas. In this study, the sensitivity analysis of electrical radiation performance...
