Abstract: A phase shifter, a fabrication method thereof, and an antenna are provided. The phase shifter includes a first substrate, a second substrate, a ground electrode disposed on a side of the first substrate facing towards the second substrate, a transmission electrode disposed on a side of the second substrate facing towards the first substrate, and liquid crystals filled between the first substrate and the second substrate. In a direction perpendicular to a plane of the second substrate, the transmission electrode overlaps with the ground electrode. The ground electrode is provided with a detection hollow part, and in the direction perpendicular to the plane of the second substrate, at least a part of the detection hollow part does not overlap with the transmission electrode.

Abstract: Provided are a liquid crystal phase shifter, a manufacturing method thereof, and a liquid crystal antenna. The liquid crystal phase shifter includes a first substrate, a second substrate, microstrips, a ground electrode, and liquid crystals located between the at least one microstrip and the ground electrode. The microstrip line is disposed on a side of the second substrate facing towards the first substrate and includes a first transmission line and a second transmission line that are each a coil and are nested with each other in a direction perpendicular to a plane of the second substrate. The coiling transmission directions of radio frequency signals transmitted on the first and second transmission lines are opposite. The ground electrode overlaps both the first transmission line and the second transmission line in the direction perpendicular to the plane of the second substrate.

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.
