Abstract

See full text

The present disclosure provides a phase shifter, a method for fabricating the same, and an antenna. The phase shifter includes a substrate, first and second transmission lines spaced apart from each other on the substrate, and at least one phase control element on the substrate. Each phase control element includes a membrane bridge and a transmission line extension which is on the substrate, between the first and second transmission lines, and electrically coupled to the first transmission line; the membrane bridge is on a side of the transmission line extension distal to the substrate, opposite to and spaced apart from the transmission line extension, and electrically coupled to the second transmission line. The membrane bridge is configured to move a portion of the membrane bridge in response to the first and second transmission lines being applied with different voltages, to change a distance from the transmission line extension.
