Abstract: A liquid crystal phase shifter and an antenna are provided. The liquid crystal phase shifter includes: first and second substrates opposite to each other, a liquid crystal layer, a first electrode, and a second electrode that are between the first and second substrates, 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. The first and second electrodes 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. The first and second shielding electrodes shield radiation generated by the first and second electrodes when the different voltages are applied to the first and second electrodes, respectively.
