Title:
LIQUID CRYSTAL ANTENNA AND PREPARATION METHOD THEREFOR, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/210825
Kind Code:
A1
Abstract:
Provided is a liquid crystal antenna, comprising: a first substrate; a second substrate, wherein the second substrate and the first substrate are arranged opposite each other; a third substrate, wherein the third substrate and the second substrate are arranged opposite each other, such that the second substrate is located between the first substrate and the third substrate; a liquid crystal layer arranged between the first substrate and the second substrate; a transmission line, wherein the transmission line is arranged on a surface, adjacent to the liquid crystal layer, of the first substrate; a grounding electrode, wherein the grounding electrode is arranged on a surface, adjacent to the liquid crystal layer, of the second substrate; and a feeder line and a radiation patch, wherein the feeder line and the radiation patch are arranged on one surface of the third substrate. The transmission line and the grounding electrode form a signal transmission line, and the transmission line and the liquid crystal layer form a phase shifter. In addition, the present disclosure further relates to a method for preparing the liquid crystal antenna, and an electronic device comprising the liquid crystal antenna.
