Abstract
Provided are a liquid crystal phase shifter and an antenna. The liquid crystal phase shifter includes a first substrate, a second substrate, a liquid crystal layer, and at least one phase shift unit. The first substrate includes a first flexible substrate and a first liquid crystal alignment layer located on a side of the first flexible substrate close to the second substrate. The second substrate includes a second flexible substrate and a second liquid crystal alignment layer located on a side of the second flexible substrate close to the first substrate. The phase shift unit includes a microstrip line and a phased electrode. The microstrip line is located between the first flexible substrate and the first liquid crystal alignment layer, and the phased electrode is located between the second flexible substrate and the second liquid crystal alignment layer.
