Abstract

This article presents the design of a 3D-printed wideband planar graded index (GRIN) lens operating on the Ka band from 25 to 40 GHz. The frequency band was chosen to cover candidate frequencies for the new 5G technology such as 28 and 38 GHz bands. The designed lens is composed of ten concentric rings. The lens shows a good wideband behavior, with a maximum gain on the broadside above 25 dB on the whole band. For the construction, the lens will be manufactured using 3D-printing with low-loss dielectric filaments. The different permittivity values of each ring are obtained by varying the infill percentage of the sections on the 3D-printing process.
