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, and a liquid crystal layer therebetween. The first substrate includes a first base plate and a first electrode thereon. The first electrode includes a main body structure on a side of the first base plate distal to the liquid crystal layer and at least one branch structure on a side of the first base plate proximal to the liquid crystal layer. The at least one branch structure is connected to the main body structure, and is spaced apart from each other in a lengthwise direction of the main body structure. The second substrate includes a second base plate and a second electrode thereon, and orthographic projections of the second electrode and the branch structure on the first base plate at least partially overlaps each other.
