In this paper, some preliminary results on the scanning capabilities of a dielectric, 3D-printable Transmitarray (TA) are presented. In a previous work, it was already proved that the TA presents a wide-band behavior, thanks to the use of an innovative dielectric unit-cell, composed of three layers: the central one has a square hole, whose constant size is changed to control the phase of the incident field; the two identical, external ones present a truncated pyramid hole, acting as a wide-band matching circuit. Here, it is shown that the behavior of the unit-cell stays almost the same for different angles of incidence, and this makes it particularly convenient for the realization of beam scanning antennas.

Abstract
In this paper, some preliminary results on the scanning capabilities of a dielectric, 3D-printable Transmitarray (TA) are presented. In a previous work, it was already proved that the TA presents a wide-band behavior, thanks to the use of an innovative dielectric unit-cell, composed of three layers: the central one has a square hole, whose constant size is changed to control the phase of the incident field; the two identical, external ones present a truncated pyramid hole, acting as a wide-band matching circuit. Here, it is shown that the behavior of the unit-cell stays almost the same for different angles of incidence, and this makes it particularly convenient for the realization of beam scanning antennas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
