Abstract
The present disclosure provides a holographic antenna and an electronic device, and belongs to the field of communication technology. The holographic antenna includes a resonant structure, which includes a first and a second dielectric substrate opposite to each other, a first electrode layer on a side of the first dielectric substrate close to the second dielectric substrate, a second electrode layer on a side of the second dielectric substrate close to the first dielectric substrate, and a tunable dielectric layer between the first and second electrode layers. The first electrode layer includes slit openings therein, and the second electrode layer includes patch electrodes thereon; orthographic projections of a slit opening and a patch electrode corresponding to each other on the first dielectric substrate at least partially overlaps with each other; and the orthographic projection of the slit opening on the first dielectric substrate at least includes an arc segment.
