Title:
FREQUENCY SELECTIVE SURFACE UNIT, FREQUENCY SELECTIVE SURFACE STRUCTURE, ELECTRONIC DEVICE, AND RADOME
Document Type and Number:
WIPO Patent Application WO/2023/159637
Kind Code:
A1
Abstract:
A frequency selective surface unit, comprising a dielectric substrate, a first resonance pattern, and a second resonance pattern. The first resonance pattern is disposed on the dielectric substrate, and the first resonance pattern comprises a plurality of protrusions. The second resonant pattern is disposed on the dielectric substrate; and an interval is formed between the second resonance pattern and the first resonance pattern in a direction parallel to the plane in which the dielectric substrate is located and/or in a direction perpendicular to the dielectric substrate.
