Abstract
A phase shifter, a phase shifter array, an antenna array and an electronic device are provided and belong to the field of communication technology. The phase shifter includes: first and second dielectric substrates opposite to each other, a first transmission line and a second transmission line on a side of the first dielectric substrate close to the second dielectric substrate, patch electrodes on a side of the second dielectric substrate close to the first dielectric substrate, and a tunable dielectric layer between a layer where the transmission lines are located and a layer where the patch electrodes are located; wherein orthographic projections of two ends of each patch electrode on the first dielectric substrate overlap with orthographic projections of the first and second transmission lines on the first dielectric substrate, respectively; and at least two of the plurality of patch electrodes are connected to different first bias voltage lines.
