Abstract: A phase shifter and an antenna device are provided. The phase shifter includes a substrate, a signal line on the substrate, ground lines in pairs on the substrate, and a capacitance adjusting component. Two ground lines in a same pair of ground lines are on both sides of the signal line and spaced apart from the signal line, respectively. The capacitance adjusting component includes a film bridge, and both ends of the film bridge are on the two ground lines, respectively. The signal line is in a space enclosed by the film bridge and the substrate. The capacitance adjusting component is configured to adjust a capacitance between the film bridge and the signal line to a target capacitance when the capacitance adjusting component receives a bias voltage, and the target capacitance has a linear correlation with a magnitude of the bias voltage.
