Abstract
A phase shifter and a method for manufacturing the same are provided. The phase shifter includes a substrate, a signal line on the substrate, ground lines in pairs and on the substrate, and at least one film bridge on the substrate and spaced apart from the signal line. Two adjacent ground lines of the ground lines are on both sides of the signal line and spaced apart from the signal line, respectively, and both ends of each film bridge are on the two adjacent ground lines, respectively. The signal line is in a space surrounded by each film bridge and the substrate. Each film bridge includes a metal layer opposite to the signal line, the metal layer has a plurality of openings therein, and the plurality of openings penetrate through the metal layer in a thickness direction of the metal layer.
