Holographic leaky-wave antenna and electronic apparatus

A holographic leaky-wave antenna, comprising:

• a first waveguide structure;
• a first dielectric substrate;
• a radiation layer;
• a first reference electrode layer;
• and
• a plurality of switching units;
• wherein the first dielectric substrate is arranged on the first waveguide structure, and there is a first gap between the first dielectric substrate and the first waveguide structure;
• the first reference electrode layer is arranged on a side of the first waveguide structure away from the first dielectric substrate;
• the radiation layer is arranged on a side of the first dielectric substrate away from the first waveguide structure, and has a plurality of slit openings therein;
• and
• the first waveguide structure comprises at least one feeding port, and an orthographic projection of the at least one feeding port on the first dielectric substrate does not overlap with an orthographic projection of the first reference electrode layer on the first dielectric substrate;
• and the plurality of switching units are in one-to-one correspondence with the plurality of slit openings, and are configured to independently control switching states of their corresponding slit openings.
