摘要： There is provided a phase shifter including a substrate, a signal line on the substrate, ground lines disposed in pairs on the substrate, and at least one film bridge. Two ground lines of the ground lines are on two sides of the signal line and are respectively spaced apart from the signal line. Each film bridge includes a plurality of connection walls and a bridge floor structure that is opposite to the substrate. The connection walls are respectively on the two ground lines. The bridge floor structure includes a phase shifting electrode and at least one pair of adsorption electrodes respectively connected to two sides of the phase shifting electrode. The phase shifting electrode is opposite to the signal line. Two adsorption electrodes in each pair are respectively opposite to the two ground lines, and are respectively connected to the connection walls on the two ground lines.

摘要： 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.

摘要： The present disclosure discloses a dimming mirror and a manufacturing method thereof, and a dimming apparatus. The dimming mirror includes a dimming layer including a plurality of dimming units. Each of the dimming units includes a first driving structure and a second driving structure opposite to each other, and an elastic supporting structure disposed between the first driving structure and the second driving structure. The first and second driving structures and the elastic supporting structure enclose a dimming chamber. The first and second driving structures are configured to adjust a dimming angle of the dimming unit by adjusting a gap width of the dimming chamber, such that a response wavelength of the dimming mirror is adjusted. The present disclosure facilitates the improvement of the flexibility of the dimming mirror.
