In this paper, some numerical results on the possibil-ity to design a 3D-printable dielectric ReflectArray (RA) antenna with beam steering capabilities are presented. The adopted unit-cell consists of a single-layer dielectric element perforated with a square hole, whose side is varied to change the phase of the reflection coefficient. Since the unit-cell behavior is quite stable with the direction of arrival of the incident field, it is used to design a 52 × 52 reflectarray working in Ka-band. Its numerical characterization proves that the RA is able to provide less than 2 dB of gain losses over a scanning range of ±30° in the vertical plane.

Abstract
In this paper, some numerical results on the possibil-ity to design a 3D-printable dielectric ReflectArray (RA) antenna with beam steering capabilities are presented. The adopted unit-cell consists of a single-layer dielectric element perforated with a square hole, whose side is varied to change the phase of the reflection coefficient. Since the unit-cell behavior is quite stable with the direction of arrival of the incident field, it is used to design a 52 × 52 reflectarray working in Ka-band. Its numerical characterization proves that the RA is able to provide less than 2 dB of gain losses over a scanning range of ±30° in the vertical plane.| File | Dimensione | Formato | |
