Abstract: An antenna includes: a dielectric layer having first and second surfaces opposite to each other; a radiating layer on the first surface, and having therein a slit; a first shielding layer on the second surface, and being electrically connected to the radiating layer; a first insulating layer on an upper side of the radiating layer; and a switch unit on an upper side of the first insulating layer, and corresponding to the slit. Each switch unit includes: a first electrode, a second insulating layer, a connecting portion, and a second electrode on the first insulating layer sequentially. Orthogonal projections of the first and second electrodes on the dielectric layer overlap each other. The connecting portion is connected to the second electrode to form a gap between the first and second electrodes. Orthogonal projections of the second electrode and a corresponding slit on the dielectric layer overlap each other.

Abstract: A phase shifter includes: a first substrate; a signal electrode and a reference electrode on at least one side of an extension direction of the signal electrode; a first insulating layer covering the reference and signal electrodes; and at least one phase controlling unit above the first insulating layer. Each phase controlling unit includes a main body portion and at least one connection portion. Orthogonal projections of the main body portion and the signal electrode on the first substrate at least partially overlap each other. The main body portion and the first insulating layer have a gap therebetween, and the connection portion is connected between the main body portion and a portion of the first insulating layer covering the reference electrode. The main body portion includes first sub-electrodes short-circuited with each other, and at least some of the first sub-electrodes are connected to a same connection portion.

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.
