This paper presents a rigorous analysis of a satellite antenna mounted onto its platform using the Dual-Grid FDTD method. In the first step of the method, the isolated antenna is analyzed. The study of the surrounded antenna is carried out in the second step of the DG-FDTD method. The results obtained in this realistic test case show the significant influence of the environment over the antenna.
