Abstract
A holographic antenna includes first and second dielectric substrates, a waveguide structure, a radiation layer, a plurality of switch units and a plurality of isolation components; 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 has a plurality of slits; the second dielectric substrate is on a side of the radiation layer away from the first dielectric substrate; the switch units and the isolation components are between the second dielectric substrate and the radiation layer; orthographic projections of each isolation component and each slit on the first dielectric substrate are first and second patterns, respectively; at least one first pattern is between two adjacent second patterns, and a first distance is between the second pattern and the first pattern closest to the second pattern.
