摘要： A phase shifter, a manufacturing method thereof and an electronic device are provided. The phase shifter includes opposite first and second substrates, and a tunable dielectric layer and first isolation components therebetween. The first substrate includes a first dielectric substrate and a first electrode on a side of the first dielectric substrate close to the tunable dielectric layer; the second substrate includes a second dielectric substrate and a second electrode on a side of the second dielectric substrate close to the tunable dielectric layer; the phase shifter includes a phase shift region and a peripheral region; the phase shift region includes overlapping regions; the first electrode and the second electrode are both in the phase shift region, and orthographic projections of the first electrode and the second electrode on the first dielectric substrate at least partly overlap with each other in the overlapping regions, to form overlapping capacitors.

摘要： The present disclosure relates to a liquid crystal phase shifter, a method for operating the liquid crystal phase shifter and an antenna. The liquid crystal phase shifter includes a first substrate, a second substrate, a liquid crystal layer and at least one adjustment unit. The one of the at least one adjustment unit includes a first electrode, a second electrode and a control circuit. The control circuit comprises a driving sub-circuit, a switching sub-circuit and a reset sub-circuit. The driving sub-circuit is configured to input a voltage to the first electrode. The reset sub-circuit is configured reset a voltage of a control terminal of the driving sub-circuit.

摘要： Provided are a phase shifter, a method for manufacturing the same, and an electronic device. The phase shifter includes: a first substrate and a second substrate that are oppositely arranged, and heat conduction structures arranged between the first substrate and the second substrate. Orthographic projections of the heat conduction structures and orthographic projections of phase shifting units on the same substrate do not overlap each other.
