1. A phase shifter, comprising a first substrate and a second substrate disposed opposite to each other, and a dielectric layer disposed between the first substrate and the second substrate; the first substrate comprises a first dielectric substrate and a first electrode arranged on a side of the first dielectric substrate close to the dielectric layer; the second substrate comprises a second dielectric substrate and a second electrode arranged on a side of the second dielectric substrate close to the dielectric layer;
the phase shifter has a phase shift region and a peripheral region; the phase shift region comprises at least one group of overlapping regions, and each group comprises a plurality of overlapping regions arranged at intervals along a transmission direction in which a microwave signal is transmitted; the first electrode and the second electrode are both located in the phase shift region, and orthographic projections of the first electrode and the second electrode on the first dielectric substrate are overlapped at least partially in the overlapping regions to form a plurality of capacitors;
the phase shifter further comprises a first auxiliary structure and a second auxiliary structure; the first auxiliary structure is located in the peripheral region and arranged on a side, close to the dielectric layer, of the first dielectric substrate; the second auxiliary structure is located in the peripheral region and arranged on a side, close to the dielectric layer, of the second dielectric substrate.
