The present application belongs to the technical field of microwave antennas. Disclosed are a millimeter wave antenna, a millimeter wave antenna array, and an active module. The millimeter wave antenna comprises: a surface choke structure, a radiation metal sheet, and a metal ground provided with a feed gap, wherein the surface choke structure comprises several metal via holes provided on a dielectric substrate 7, the dielectric substrate 7 is arranged on the metal ground, and the radiation metal sheet is electrically connected to the metal ground by means of the metal via holes; and the surface choke structure is used for suppressing the interference caused by surface waves on the radiation performance of the antenna. A surface wave choke structure is used, such that the problem of skewing of a digital array antenna pattern caused by an environmental factor and surface wave interference can be effectively solved; moreover, the surface wave choke structure is arranged inside an antenna, such that a space occupied on a base material (such as a PCB and a chip package) is reduced, and the advantage of low costs is achieved.
