Abstract

See full text

A phase shifter and a method for operating the same, an antenna and a communication device are provided. The phase shifter includes: a first substrate and a second substrate opposite to each other; a dielectric layer between the first substrate and the second substrate; a first electrode on a side of the first substrate proximal to the second substrate; a second electrode on a side of the second substrate proximal to the first substrate; and a ground electrode on a side of the second substrate distal to the first substrate. The dielectric layer includes liquid crystal molecules, and the first electrode and the second electrode are configured to control rotation of the liquid crystal molecules according to different voltages respectively received by the first electrode and the second electrode. The second electrode has a one-piece structure.
