Antenna polarization is a parameter that describes the vector spatial orientation of electromagnetic waves radiated by an antenna. Since the electric field and the magnetic field have a constant relationship, the polarization direction of electromagnetic waves radiated from the antenna is generally directed in a space of an electric field vector. When the antenna polarization mode of the receiving end is consistent with that of the antenna, a larger signal can be obtained, and the receiving end is mainly used for resisting interference. For example, when the vertically polarized satellite receiving antenna is directed to two satellites of horizontal polarization and vertical polarization, the vertically polarized signal can be successfully received, and the horizontally polarized signal can be suppressed. In order to fully utilize spectrum resources and avoid interference, satellite broadcasting generally adopts a multi-polarization mode.
