Abstract
A spatial filter, a driving method thereof and an electronic device are provided, and belong to the field of wireless communication technology. The spatial filter of the present disclosure includes at least one filter structure; wherein each filter structure includes a first substrate, a second substrate opposite to the first substrate, and a dielectric layer between the first substrate and the second substrate; wherein the first substrate includes a first dielectric substrate and at least one first electrode on a side of the first dielectric substrate close to the dielectric layer; the second substrate includes a second dielectric substrate and at least one second electrode on a side of the second dielectric substrate close to the dielectric layer; and the at least one first electrode intersects with the at least one second electrode, which defines at least one resonant unit configured to filter an electromagnetic wave.
