Abstract: A holographic leaky-wave antenna includes a first waveguide structure, a first dielectric substrate, a radiation layer, and a first reference electrode layer. The first dielectric substrate is arranged on the first waveguide structure and has a first gap with the waveguide structure. The first reference electrode layer is arranged on a side of the first waveguide structure distal to the first dielectric substrate. The radiation layer is arranged on a side of the first dielectric substrate distal to the first waveguide structure, and has a plurality of slit openings therein. The holographic leaky-wave antenna further comprises a plurality of feeding ports configured on the first waveguide structure, and an orthogonal projection of each of the plurality of feeding ports on the first dielectric substrate does not overlap with an orthogonal projection of the first reference electrode layer on the first dielectric substrate.
