Title:
CONTROL METHOD FOR LIQUID CRYSTAL REFLECTARRAY ANTENNA, AND DEVICE, APPARATUS, PROGRAM AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/226707
Kind Code:
A9
Abstract:
The present disclosure belongs to the technical field of antenna control. Provided are a control method for a liquid crystal reflectarray antenna, and a device, an apparatus, a program and a medium. The method comprises: acquiring the distance between a liquid crystal reflectarray antenna and a feed source antenna, a target array surface temperature of the liquid crystal reflectarray antenna, and beam control data; calculating a target reflection phase of the liquid crystal reflectarray antenna on the basis of the distance and the beam control data; querying a driving voltage mapping relationship to find a target driving voltage matching the target reflection phase and the target array surface temperature, wherein the driving voltage mapping relationship comprises: a mapping relationship between the driving voltage, the array surface temperature and the reflection phase of the liquid crystal reflectarray antenna; and according to the target driving voltage, controlling the liquid crystal reflectarray antenna to compensate for the target reflection phase with a phase. Therefore, the influence of an operation temperature on a reflection phase of a liquid crystal reflectarray antenna is reduced.
