A Millimeter-Wave Fresnel Zone Plate Lens Design Using Perforated 3D Printing Material

This paper presents a novel Fresnel Zone Plate Lens (FZPL) using perforated 3D printing material at 60 GHz (λ
₀
= 5.45 mm). A gradient refractive index condition is controlled using the air-hole approach in the dielectric slab. This structure employs on conical horn antenna as a beam launcher for focusing applications. The proposed FZPL lens is a flat type lens with half phase correction properties. A recommended prototype planar lens is performed on the 3mm thickness of a plastic material with a constant relative permittivity. Throughout this paper, the lens antenna design process at millimeter wave frequency band has been demonstrated for V-band applications.
