Abstract
A liquid crystal antenna includes an upper substrate, a lower substrate, a liquid crystal layer, a first metal layer, and a second metal layer. The liquid crystal layer is disposed between the two substrates. The first metal layer is located between the lower substrate and the liquid crystal layer, and includes two opposite differential signal lines electrically connected to two electrode wires, respectively. The two differential signal lines and the two electrode wires form a mirror symmetry with a virtual ground line being an axis of symmetry. The second metal layer is located between the upper substrate and the liquid crystal layer, and includes a plurality of line segments arranged at intervals. Vertical projections of the line segments overlap with the two differential signal lines. The second metal layer forms a mirror symmetry with a virtual symmetry plane including the virtual ground line and perpendicular to the two substrates.
