Holographic antenna with isolation components and electronic device

A holographic antenna, comprising a first dielectric substrate, a second dielectric substrate, a waveguide structure, a radiation layer and a plurality of switch units;

• wherein the first dielectric substrate is on a waveguide port of the waveguide structure;
• the radiation layer is on a side of the first dielectric substrate away from the waveguide structure, and the radiation layer is provided with a plurality of slits;
• the second dielectric substrate is on a side of the radiation layer away from the first dielectric substrate;
• the plurality of switch units are between the second dielectric substrate and the radiation layer, and are in one-to-one correspondence with the plurality of slits;
• wherein the holographic antenna further comprises a plurality of isolation components between the second dielectric substrate and the radiation layer;
• an orthographic projection of each of the plurality of isolation components on the first dielectric substrate is a first pattern, and an orthographic projection of each of the plurality of slits on the first dielectric substrate is a second pattern;
• at least one of the first patterns is between two of the second patterns adjacent to each other, and a first distance is between the second pattern and the first pattern closest to the second pattern,
• wherein each of the plurality of slits extends in a second direction, and for any one of the second patterns, two of the first patterns are on both sides of the second pattern extending in the second direction, respectively.
