Title:
ANTENNA DEVICE AND MANUFACTURING METHOD THEREFOR, CONTROL METHOD, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/070522
Kind Code:
A1
Abstract:
The present disclosure provides an antenna device and a manufacturing method therefor, a control method, and an electronic device. The antenna device comprises a first substrate structure, a second substrate structure, and a liquid crystal layer located between the first substrate structure and the second substrate structure. The first substrate structure comprises a first substrate and multiple antenna patches located on a first side of the first substrate. The second substrate structure is located on the sides of the multiple antenna patches far away from the first substrate, and comprises a second substrate and a metal layer having multiple gaps, the metal layer being located on the second side of the second substrate close to the first substrate. One gap corresponds to one antenna patch, the region where the orthographic projection of each gap on the first substrate overlaps the orthographic projection of the corresponding antenna patch on the first substrate is a first region, the orthographic projection of each gap on the first substrate further comprises a second region and a third region, and the third region is located between the second region and the third region.
