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.

Abstract: A phase shifter and a wireless communication device are provided. The phase shifter includes a first substrate, a radio frequency transmission line arranged on a side of the first substrate, and a bias line connected to the radio frequency transmission line. The bias line includes a first wire and a second wire. A sheet resistance of the second wire is greater than a sheet resistance of the radio frequency transmission line. The first wire and the radio frequency transmission line are connected and form an integrated structure. A line width of the first wire is less than a line width of the radio frequency transmission line. The second wire and the first wire form a lapping region in an extension direction of the first wire. In the lapping region, the second wire is arranged on a side of the first wire away from the first substrate.
