    Abstract: 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.

    Abstract: A phase shifter includes first and second dielectric substrates opposite to each other and a plurality of phase shift units between the first and the second dielectric substrates; the phase shift unit includes first and second electrode layers and an adjustable dielectric layer between the first and the second electrode layers; orthographic projections of the first and second electrode layers on the first dielectric substrate at least partially overlap each other, and at least one accommodation cell of the phase shift unit is defined in a region where the orthographic projections of the first and second electrode layers on the first dielectric substrate overlap each other; the adjustable dielectric layer is in at least the accommodation cell; and cell gaps of the accommodation cells of at least a part of the plurality of phase shift units are different from each other.
