Abstract
A phase shifter and an antenna are provided. The phase shifter includes: oppositely arranged first and second substrates; a medium layer between the first and second substrates and having an adjustable dielectric constant; a phase shift unit including a transmission line and a phase control electrode, the transmission line being between the first substrate and the medium layer, and the phase control electrode being between the second substrate and the medium layer; and multiple first wires for regulating an electric field between the transmission line and the phase control electrode, an orthographic projection of the first wires onto the first substrate being parallel to an orthographic projection of the transmission line onto the first substrate, the orthographic projection of the first wires onto the first substrate being on opposite sides of the orthographic projection of the transmission line onto the first substrate.
