Abstract
The present disclosure provides a phase shifter and antenna. The phase shifter includes a first substrate, a second substrate and a first dielectric layer between the first substrate and the second substrate. The first substrate includes: a first base substrate and a transmission line on a side of the first base substrate proximal to the first dielectric layer. The second substrate includes: a second base substrate and a reference electrode on a side of the second substrate proximal to the first dielectric layer. An orthographic projection of the reference electrode on the first base substrate at least partially overlaps an orthographic projection of the transmission line on the first base substrate. The reference electrode is provided with a first opening therein, and a length of the first opening along the first direction is not less than a line width of the transmission line.
