In this paper, the design of a beam scanning, 3D-printed dielectric Transmitarray (TA) working in Ka-band is discussed. Thanks to use an innovative three-layer unit-cell that exploits tapered sections enhance bandwidth, 50 × elements transmitarray with improved scanning capabilities and wideband behavior has been designed experimentally validated. The measured radiation performances over coverage ±27 ∘ shown variation gain lower than 2.9 dB 1-dB bandwidth any case higher 23%. promising results suggest proposed TA technology valid alternative realize passive multibeam antenna, additional advantage it can be easily manufactured using 3D-printing techniques.
