Title:
ANTENNA DEVICE AND PHASED ARRAY ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/188903
Kind Code:
A1
Abstract:
This antenna device includes: a strip conductor layer; a radiating conductor layer that continues from the strip conductor layer; a ground conductor layer that faces the strip conductor layer and the radiating conductor layer; a liquid crystal layer between the strip conductor layer and the radiating conductor layer, and the ground conductor layer; and an oriented film between the strip conductor layer and the radiating conductor layer, and the liquid crystal layer. The oriented film is provided such that the orientations of liquid crystal molecules of the liquid crystal layer are different in a first region that overlaps the strip conductor layer and a second region that overlaps the radiating conductor layer.
