Abstract
The paper shows the practicability of entirely manufacturing complex antennas, as a folded reflectarray operating in Ku band, by using a low cost plastic 3D printer. All the antenna parts have been printed, not only the antenna supports, but also the feeder, the polarizer, and the reflectarray substrate. Then, the plastic parts have been opportunely metalized or by using conductive silver based spray, or by sticking on it an adhesive copper sheet appositely cut with a vinyl cutter plotter. Some strategies to reduce the influence of the not accurate knowledge of the material characteristics, and a few manufacturing tricks are also reported.
