Novel 3D-Printed Reconfigurable Origami Frequency Selective Surfaces with Flexible Inkjet-Printed Conductor Traces

This work outlines the first-of-its-kind integration of 3D and inkjet printing additive manufacturing processes for the realization of tunable origami structures. The outcome of this process demonstrated a tremendous structural strength improvement over paper-based origami structures, also featuring very good potential for more complicated origami-inspired designs. A mm-wave 4D tunable Miura-shaped frequency selective surface (FSS) is demonstrated using this process. This FSS shows both frequency and bandwidth tunability, and has excellent angle of incidence rejection.
