Abstract
A liquid crystal phase shifter includes a first substrate and a second substrate which are disposed oppositely, and a liquid crystal layer located between the first substrate and the second substrate. A first metal film layer is disposed on a side of the first substrate facing the second substrate. A second metal film layer is disposed on a side of the second substrate facing the first substrate. The first metal film layer and the second metal film layer are both patterned metal film layers. The first substrate and the second substrate are both PCBs. The present disclosure further provides a liquid crystal antenna, including the abovementioned liquid crystal phase shifter. The present disclosure further provides a manufacturing method of the liquid crystal phase shifter.
