Title:
PHASE-SHIFT CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/074045
Kind Code:
A1
Abstract:
The present disclosure provides a phase-shift control system and method. The system comprises: a capacitance measurement module, used for measuring a capacitance value between a signal transmission line and a ground layer; and a voltage control module, separately connected to the signal transmission line and the ground layer in a liquid crystal phase shifter and used for adjusting a voltage according to an actual measured value of a dielectric constant of a liquid crystal layer until the difference value between the voltage and a target voltage is less than or equal to a preset deviation.
