The invention belongs to the field of satellite mobile communication and relates to a circularly polarized antenna design, in particular to a circularly polarized dipole antenna for satellite communication. The circularly polarized dipole antenna has the advantages of wide band, wide wave beam and good low-elevation angle circular polarization performance. The circularly polarized dipole antenna comprises a dielectric substrate, a metal reflecting plate, four dipole antenna radiation arms, four parasitic patches, four metal conductive walls and a coaxial feeder; the conductive walls capable ofbroadening lobes are applied to the circularly polarized crossed dipole antenna in a combined manner; the metal reflecting ground plate, the conductive walls and the parasitic patches jointly form magnetic dipole antennas; lobe broadening is carried out on the basis of the complementation of the radiation patterns of the magnetic dipoles and the electric dipoles, so that gain at a low elevation angle can be improved; and thus, the circularly polarized dipole antenna for satellite communication has the advantages of wide band, wide wave beam, low elevation angle, good circular polarization performance, simple structure and easiness in installation, and is more suitable for satellite communication.
