Abstract
The disclosure provides a liquid crystal antenna including: a first substrate; a second substrate facing the first substrate; a third substrate facing the second substrate such that the second substrate is between the first substrate and the third substrate; a liquid crystal layer between the first substrate and the second substrate; a transmission line on a surface of the first substrate adjacent to the liquid crystal layer; a ground electrode on a surface of the second substrate adjacent to the liquid crystal layer; a feeder line and a radiation patch both on a surface of the third substrate, wherein the transmission line and the ground electrode form a signal transmission circuit, and the transmission line and the liquid crystal layer form a phase shifter. In addition, the disclosure also relates to a method for manufacturing the liquid crystal antenna and an electronic device including the liquid crystal antenna.
