This paper presents a multiphysics analysis of a space-based communication satellite dish antenna. Electromagnetic losses due to induced high-frequency surface currents lead to partial, asymmetric heatingof the structure, causing stress and deformation. A final electromagnetic analysis is performed on the resultingdeformed structure to determine the effect of the deformation on the antenna pattern and overall performance.
