This thesis presents a numerical analysis of beam aberration effects for ESA's new DSA4, utilizing Ticra’s Grasp software for accurate and efficient simulations. The study focuses on identifying optimal tilting angles for mirrors M8 and M12 to minimize beam aberration losses within ESA specifications. Additional tests evaluated the robustness of these compensations, considering a Left-Hand Circular Polarization (LHCP) Ka-Tx feed,, as well as various antenna pointing directions from the zenith.
