ANTENNA APPARATUS, ELECTRONIC ASSEMBLY, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/065828
Kind Code:
A1
Abstract:
An antenna apparatus, an electronic assembly, an electronic device, a communication apparatus, and a method for manufacturing the antenna apparatus. The antenna apparatus comprises: a plurality of antenna unit arrays, wherein the plurality of antenna unit arrays each comprise antenna units, and each antenna unit comprises a transceiving unit configured to transmit and receive a signal and a phase modulation unit configured to perform phase modulation on the signal, wherein the phase modulation unit comprises a first metal layer extending in a first direction perpendicular to a first plane which comprises a plane formed by expanding the corresponding antenna unit array, a second metal layer extending in the first direction, and a liquid crystal layer located between the first metal layer and the second metal and extending in the first direction; and a bias component coupled to the antenna unit arrays in the first direction, wherein the bias component comprises bias line pairs coupled to the antenna units, and each bias line pair comprises a first bias line at least a portion of which extends in the first direction and is coupled to the first metal layer in the corresponding antenna unit, and a second bias line at least a portion of which extends in the first direction and is coupled to the second metal layer in the corresponding antenna unit.
