Abstract
A phase shifter, including: first and second substrates opposite to each other; an adjustable dielectric layer and a plurality of pillar supports between the first and second substrates; first and second conductive layers on sides of first and second substrates close to the adjustable dielectric layer, respectively, where patterns of the first and second conductive layers include at least one first electrode and at least one second electrode, respectively, orthographic projections of the at least one first electrode and the at least one second electrode on the first substrate at least partially overlap each other; orthographic projections of each of the plurality of pillar support, and the pattern of the first conductive layer on the first substrate do not overlap each other, and the pillar supports of the plurality of pillar supports close to an edge of the pattern of the first conductive layer are equally spaced apart therefrom.
