Abstract: An antenna structure includes a first substrate and a second substrate. There is a dielectric layer between the first substrate and the second substrate. The first substrate includes a first dielectric substrate, and a radiation patch and a micro-strip arranged on the first dielectric substrate. The radiation patch and the micro-strip are on one side of the first dielectric substrate away from the second substrate. Orthographic projections of the micro-strip and the radiation patch on the first dielectric substrate do not overlap. The radiation patch has at least one first slot away from the micro-strip. The second substrate includes a second dielectric substrate, a feed structure arranged on one side of the second dielectric substrate close to the first substrate, and a ground layer arranged on one side of the second dielectric substrate away from the first substrate. The feed structure is electrically connected to the micro-strip.

Abstract: Provided are a phase shifter, a driving method therefor and an antenna. The phase shifter includes a first substrate and a second substrate, which are disposed opposite to each other, and a first dielectric layer disposed therebetween; the first substrate includes: a first base, and a first reference electrode layer disposed on a side of the first base close to the first dielectric layer, and including first reference electrodes insulated and spaced apart from one another and each having a first opening; the second substrate includes a second base, first transmission lines on the second base and spaced apart from one another; the first transmission lines are in one-to-one correspondence with the first reference electrodes; an orthographic projection of a first transmission end of each first transmission line on the second base at least partially overlaps that of the first opening corresponding thereto on the second base.

Abstract: Provided is an antenna unit, including a first substrate and a second substrate that are oppositely disposed, a liquid crystal layer located between the first substrate and the second substrate, and a third substrate located on a side of the second substrate away from the liquid crystal layer. The first substrate includes a first base substrate and a radiation unit layer. The second substrate includes a second base substrate and a ground layer. The radiation unit layer and the ground layer face the liquid crystal layer. The third substrate includes a third base substrate and a feed structure layer, wherein the feed structure layer is located on a side of the third base substrate away from the second substrate.
