ABSTRACT:
The invention relates to apparatus for converting electromagnetic waves with a particular polarization into waves having circular polarization wherein a single or multi-layer conductor grid structure is placed in front of the radiation aperture. If it is necessary due to spatial requirements of the radome, the circular polarization grid may be non-planar and according to the invention the geometric development of the grid structure can be determined by projecting a desired grid structure disposed in the radiation aperture plane upon a non-planar such as a cone-shaped surface. The manufacture of the grid structure can be accomplished by first forming the grid structure on a surface such as plastic with conducting strips or members formed thereon and so arranged such that when the plastic sheet is formed into a cone by removing a pie-shaped segment the desired non-planar pattern results.
