1. An antenna comprising:
a first dielectric layer having a first surface and a second surface arranged opposite to each other in a thickness direction of the first dielectric layer;
a radiation patch, which is arranged on the first surface of the first dielectric layer;
a first electrode layer, which is arranged on the second surface of the first dielectric layer, and at least partially overlaps with an orthographic projection of the radiation patch on the second surface;
wherein the first electrode layer has an inner recess, and openings of the inner recess face the radiation patch, and an orthographic projection of at least part of a radiation edge of the radiation patch on the first dielectric layer at least partially overlaps with an orthographic projection of the inner recess on the first surface; a depth of the inner recess is ¼ equivalent wavelength.
