摘要：
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.
