The proposed reflector with discretely distributed impedance is designed as a planar Fresnel lens. The surface of the lens consists of several alternating even and odd Fresnel zones. The surface of the zones if one group, for example the odd zones, a coated with high-conductive material. The zones of the other group, for example the even zones, a coated with material that provides the surface impedance (the ratio between the module of the vector of electric field strength and the module of the vector of the magnetic field strength) exceeds the characteristic impedance of free space.
