The transmission line includes signal line segments, any adjacent two of which have a gap therebetween to define a connection region. The phase shifter further includes at least one phase shifting unit each including: a film bridge extending in the first direction, a connection electrode extending in a second direction, and an interlayer insulating layer on a side of the connection electrode distal to the substrate. Both ends of the connection electrode are respectively connected with the first and second reference electrodes, and an orthogonal projection of the connection electrode on the substrate is in the connection region. Both ends of the film bridge are respectively connected with adjacent two signal line segments.
