Title:
TUNABLE PHASE SHIFTER AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/020792
Kind Code:
A1
Abstract:
The present application provides a tunable phase shifter and an electronic device, and relates to the technical field of microwave radiofrequency. The tunable phase shifter comprises a first substrate and a second substrate; a tunable dielectric layer; a first electrode layer comprising a reference electrode; and a second electrode layer comprising a first transmission line and a second transmission line. A first branch is provided on the first transmission line and a second branch is provided on the second transmission line, the orthographic projections of the first branch and of the second branch on the first substrate at least partially overlapping with the orthographic projection of the reference electrode on the first substrate. The tunable phase shifter provided by the present application forms an electric field by means of the first branch, the second branch and the reference electrode, thereby achieving a phase shifting effect.
