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.
