© 2017 IEEE. A technique for the design of low side-lobe pyramidal horn antennas loaded with a thin single-layer metasurface lens is extended using a subwavelength-size element. The single dielectric lens is printed on both sides with two identical subwavelength metallic square-ring resonators arrays. By placing the metasurface lens inside an existing standard horn antenna, both amplitudes and phases of electromagnetic waves can be controlled. An example is given of a metamaterial lens and horn (metahorn) antenna that simultaneously possesses high gain and low sidelobes. The measurement of this metahorn shows a 35-dB reduction of the first sidelobe level in the E plane, compared with that of the original air-filled standard pyramidal horn.
