Abstract
A liquid crystal phase shifter and an electronic device. The liquid crystal phase shifter includes a first substrate and a second substrate arranged opposite to each other, a liquid crystal layer, a first electrode and a second electrode. The liquid crystal layer is between the first substrate and the second substrate. The first electrode is on the first substrate. The second electrode is on the second substrate. The second electrode includes a connection portion and a plurality of concentric annular structures, at least one of the concentric annular structures includes a plurality of protruded portions, at least another of the concentric annular structures includes a plurality of recessed portions, and the connection portion is electrically connected to each of the concentric annular structures.
