Title:
PHASE SHIFTER AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/184078
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of communications, and provides a phase shifter and an electronic device. A phase shifter of the present disclosure, comprising: a first dielectric substrate, a first feed structure, a second feed structure, and a phase-shifting structure. The phase-shifting structure comprises a first signal electrode, a first reference electrode, a first insulating layer, and at least one phase control unit, wherein the phase control unit is provided on the side of the first insulting layer away from the first dielectric substrate; the phase control unit comprises at least one membrane bridge; a gap is formed between the bridge surface of the membrane bridge and the first insulating layer, and the bridge surface of the membrane bridge overlaps the orthographic projections of the first signal electrode and the first reference electrode on the first dielectric substrate. The first feed structure comprises a second signal electrode, and the second feed structure comprises a third signal electrode, wherein the second signal electrode and the third signal electrode are respectively connected to a first end and a second end of the first signal electrode. The phase shifter further comprises at least one first bias signal line, wherein the first bias signal line is connected to the second signal electrode or the third signal electrode.
