The invention provides a wide-angle circularly-polarized super surface antenna comprising a super surface structure and a half-wavelength dipole antenna placed at a certain height right above the super surface structure. The super surface structure is formed by periodically extending super surface units in the x and y directions according to a certain period respectively, and a super surface unit m*n gap-free arrangement structure is formed, wherein m and n are natural numbers greater than or equal to 2. Each super surface unit is composed of a dielectric substrate, a grounding plate arranged on one side of the dielectric substrate, and a double-arrow-shaped metal patch arranged on the other side of the dielectric substrate. According to the invention, circularly-polarized radiation wave can be generated in a space above the dipole antenna, and by changing the sizes of the super surface units and the dipole antenna and the vertical distance between the super surface units and the dipole antenna, the super surface antenna is enabled to work in different frequency bands. The wide-angle circularly-polarized super surface antenna of the invention has a series of advantages of simple structure, easy frequency adjustment, wide circular polarization angle, radar scattering cross section reduction, and the like.
