Resumo:	This paper presents a NF-focused antenna based on a low-cost dielectric planar lens. The working principle is based on the variation of dielectric material density in order to obtain a variation in the effective ?_r. A prototype in the 28GHz band is designed and manufactured with a 3D printer using Polylactic Acid (PLA) material. The breadboard is simulated with a full wave tool and measured in an XYZ planar range, resulting in a very good agreement between simulations and measurements.
