The invention discloses a satellite communication antenna based on a parallel differential driving mechanism and a servo control method thereof, and belongs to the technical field of antennas. The antenna seat frame is a two-degree-of-freedom parallel differential mechanism, the reflector adopts a microstrip planar array antenna, and a mathematical model method for establishing two independent degrees of freedom at the input end of the parallel differential mechanism and two independent orthogonal degrees of freedom at the output end of the parallel differential mechanism is provided. The method comprises the following steps of: providing a corresponding relationship between an azimuth angle and a pitch angle of an antenna and two degrees of freedom of an output end of an antenna seat frame, establishing a mathematical model solution of the azimuth angle and the pitch angle of the antenna, and establishing a mathematical model solution pointing to a theoretical position in antenna servo control on the basis o
