Document Type and Number:
WIPO Patent Application WO/2023/245590
Kind Code:
A1
Abstract:
The present disclosure belongs to the technical field of communications. Provided are a holographic antenna and an electronic device. The holographic antenna of the present disclosure comprises a resonant structure. The resonant structure comprises a first dielectric substrate and a second dielectric substrate, which are opposite each other, a first electrode layer arranged on the side of the first dielectric substrate close to the second dielectric substrate, a second electrode layer arranged on the side of the second dielectric substrate close to the first dielectric substrate, and a tunable dielectric layer arranged between the first electrode layer and the second electrode layer. The first electrode layer has a plurality of slot openings, the second electrode layer comprises a plurality of patch electrodes, and orthographic projections of one patch electrode and one slot opening on the first dielectric substrate at least partially overlap each other; and an orthographic projection of each slot opening on the first dielectric substrate at least comprises an arc segment.
