Abstract
Liquid crystal antenna, splicing liquid crystal antenna, and method of forming liquid crystal antenna are provided. The liquid crystal antenna includes support structures, liquid crystals, a first substrate and a second substrate. The first substrate and the second substrate are arranged oppositely, the support structures are arranged between the first substrate and the second substrate, the first substrate includes first metal layers arranged on a side of the first substrate facing the second substrate, the second substrate includes a second metal layer arranged on a side of the second substrate facing the first substrate. The second metal layer includes functional part and spacers, the functional parts and the first metal layers are stacked along a first direction perpendicular to the second substrate, and the functional parts at least partially overlap the first metal layers. The support structures are arranged between the spacers and the first metal layers.
