Abstract
The present application provides a tunable phase shifter and an electronic device, which relates to the technical field of microwave radio frequency. The tunable phase shifter includes: a first substrate and a second substrate; and a regulatable dielectric layer. The first electrode layer includes a reference electrode. The second electrode layer includes a first transmission line and a second transmission line, the first transmission line is provided with a first branch, the second transmission line is provided with a second branch, and the orthographic projections on the first substrate of the first branch and the second branch and the orthographic projection of the reference electrode on the first substrate at least partially overlap. The tunable phase shifter according to the present application forms an electric field by using the first branch, the second branch and the reference electrode, which can realize the function of phase shifting.
