1. A phase shifter, comprising:
a first substrate and a second substrate arranged opposite to each other;
a medium layer located between the first substrate and the second substrate, wherein a dielectric constant of the medium layer is adjustable;
a phase shift unit, wherein the phase shift unit comprises a transmission line and a phase control electrode, the transmission line is arranged between the first substrate and the medium layer, and the phase control electrode is arranged between the second substrate and the medium layer; and
a plurality of first wires, wherein the plurality of first wires are used for regulating an electric field between the transmission line and the phase control electrode, and an orthographic projection of the plurality of first wires onto the first substrate is parallel to an orthographic projection of the transmission line onto the first substrate, the orthographic projection of the plurality of first wires onto the first substrate is on both sides of the orthographic projection of the transmission line onto the first substrate, and the plurality of first wires are spaced from the transmission line by a first distance in a line width direction of the transmission line.
