Abstract (en)
The present application provides a phase shift control system and method, the system includes: a capacitance detecting module, used for detecting a capacitance value between a radio frequency transmission line and a ground layer; and a voltage controlling module, connected to a radio frequency transmission line of a liquid crystal phase shifter and a ground layer of the liquid crystal phase shifter, and used for adjusting, based on an actual measured value of a dielectric constant of a liquid crystal layer, a voltage until a difference value between the voltage and a target voltage is less than or equal to a preset deviation.
