ANTENNA AND COMMUNICATION SYSTEM

The present disclosure provides an antenna and a communication system, and belongs to the technical field of communications. The antenna of the present disclosure comprises a first substrate and a second substrate that are disposed opposite one another. The first substrate comprises: a first dielectric substrate, having a first surface and a second surface that are disposed opposite one another; a reference electrode layer, provided on the first surface; at least one first radiation portion, which is provided on the second surface and which at least partially overlaps with the orthographic projection of the reference electrode layer on the first dielectric substrate; and at least one feed structure, which is provided on the second surface, is electrically connected to the first radiation portion, and at least partially overlaps with the orthographic projection of the reference electrode layer on the first dielectric substrate. The second substrate comprises: a second dielectric substrate, which is disposed op
