Classification: CPC H | IPC H

Claim 0:
1. A liquid crystal phase shifter, comprising: a first substrate and a second substrate opposite to each other, a liquid crystal layer, a first electrode, and a second electrode that are between the first substrate and the second substrate, a first shielding electrode on a side of the first substrate distal to the liquid crystal layer, and a second shielding electrode on a side of the second substrate distal to the liquid crystal layer, wherein
the first electrode and the second electrode are configured to generate an electric field when being provided with different voltages, respectively, to change a dielectric constant of the liquid crystal layer so as to adjust a phase shifting degree of a microwave signal; and
the first shielding electrode and the second shielding electrode are configured to shield radiation generated by the first electrode and the second electrode when the different voltages are applied to the first electrode and the second electrode, respectively.
