The invention discloses a millimeter wave antenna for low-orbit satellite communication. The millimeter wave antenna comprises a dielectric substrate, a first circular polarization radiator, seven conductor columns, a 90-degree arc, a second circular polarization radiator, a ground plane and a feed point. The dielectric substrate is provided with four layers of conductors. The first circularly polarized radiator is arranged on the first layer and provides a first Ku wave band mode and a first Ka wave band mode. And seven conductor columns are vertically connected with the four layers of conductors and are uniformly arranged on the left side of the first circularly polarized radiator in a semi-arc manner. The circle center of the 90-degree arc is the projection of the first circle center on the second layer, and the second end of the 90-degree arc is connected with the first circularly polarized radiator through a through hole, so that the polarization of the first Ku wave band mode and ...
