Abstract: A liquid crystal antenna and a method for forming a liquid crystal antenna are provided. The liquid crystal antenna includes a first substrate; a second substrate opposite to the first substrate; and a liquid crystal layer disposed between the first substrate and the second substrate. A first conductive layer is disposed on a side of the first substrate facing toward the second substrate; a second conductive layer is disposed on a side of the second substrate facing toward the first substrate; the second conductive layer at least includes a plurality of radiation electrodes; an external metal layer is disposed on a side of the first substrate facing away from the liquid crystal layer; and the external metal layer is connected to a fixed potential.
