Patent attributes
The present disclosure relates to a curved conformal frequency selective surface (FSS) radome. The radome includes a dielectric radome and a curved conformal FSS array arranged on an outer wall of the dielectric radome, where the dielectric radome includes a dome, a circular truncated cone and a hollow cylinder which are integrally formed from top to bottom, and the curved conformal FSS array is formed by periodically arraying foldable FSS units on an outer surface of the dielectric radome, the foldable FSS unit being of an axially symmetrical and centrally symmetrical gap structure, and having an overall shape consisting of foldable gaps on a left side, an upper side, a right side and a lower side, the four foldable gaps being sequentially connected in a square shape, and remaining parts of the foldable FSS unit except for the four foldable gaps being all metal patches.
