Abstract: An antenna and its fabrication method, and a display device are provided. The antenna includes a substrate, a radiation electrode, a first dummy electrode, and a feed line. The radiation electrode, the first dummy electrode, and the feed line are disposed on the substrate. The feed line is coupled and connected to the radiation electrode. The first dummy electrode and the radiation electrode are adjacent but not connected to each other. Along a first direction, an orthographic projection of the radiation electrode to a plane where the substrate is located is a first projection, and an orthographic projection of the first dummy electrode to the plane where the substrate is located is a second projection. There is a first interval between the first projection and the second projection; and the first direction is perpendicular to the plane where the substrate is located.
