Abstract

A phase shifter and an electronic device are provided and belong to the field of communication technology. The phase shifter includes opposite first and second substrates; a tunable dielectric layer therebetween. The first substrate includes a first dielectric substrate; first and second transmission lines on a side of the first dielectric substrate close to the tunable dielectric layer; the first transmission line includes a first main line and at least one first branch connected to a side of an extending direction thereof; the second transmission line includes a second main line and at least one second branch connected to a side of an extending direction thereof; the first and second main lines are arranged side by side with a first gap therebetween. The second substrate includes a second dielectric substrate and a first electrode layer on a side of the second dielectric substrate close to the tunable dielectric layer.
