Abstract
A phase shifter and a preparation method thereof, and an electronic device. The phase shifter includes: an adjustable dielectric layer, arranged between a first electrode layer and a second electrode layer, and including a first support structure, wherein the first support structure is arranged on at least one side of a first region, and an orthographic projection of the first support structure on a first base plate is at least non-overlapping with an orthographic projection of the first region on the first base plate. The phase shifter provided in the present application is arranged in the non-capacitive overlap region between the first base plate and the second base plate through the first support structure, which can not only provide good support, but also reduce or even eliminate the impact on phase shifting, achieving large phase shift amount, high uniformity of phase shift degrees, and low loss.
