Dual linearly polarised 3D printed Phoenix cell for wide band metal only reflectarrays

摘要

This study shows the potential of additive manufacturing for the fabrication of 3D Phoenix phase-shifting cell. With traditional microstrip printing technology, the cell has many advantages. Here, the authors demonstrate that the 3D printed version of the cell exhibits very good intrinsic performances in the 17-21 GHz frequency band. A deep insight into the operation mode of the cell is drawn in order to have a better understanding of its behaviour. Different prototypes are fabricated and measured to validate experimentally the numerical results.
