Abstract
The present disclosure provides a phase shifting device, a driving method thereof, and an antenna. The phase shifting device of the present disclosure includes: data lines, scan lines and phase shifting units. Each phase shifting unit includes: a switch sub-circuit and a phase shifter. Control terminals of the switch sub-circuits in a same row are coupled to a same scan line, first terminals of the switch sub-circuits in a same column are coupled to a same data line, and a second terminal of each switch sub-circuit is coupled to a phase shifter included in the phase shifting unit to which the switch sub-circuit belongs. Each switch sub-circuit is configured to transmit, in response to a switch control signal provided by the scan line, a data voltage signal provided by the data line to the phase shifter to drive the phase shifter.
