Abstract
The present disclosure provides a phased-array antenna and a control method thereof. The phased-array antenna includes two parallel substrates attached by sealant into a cavity filled with liquid crystals, a plurality of phase-shifting units is provided in the cavity defined. Each unit comprises: a power feeder electrically connected to a radio frequency signal terminal, a radiator electrically connected to the power feeder, a ground electrode electrically connected to a ground signal terminal but electrically insulated from the power feeder and the radiator respectively, and a driving electrode electrically connected to a control signal wire. The orthographic projections of the driving electrode, the power feeder, and the ground electrode overlap on one substrate.
