TY - JOUR AU1 - Hehn, Tobias AU2 - Zimmer, Felix AU3 - Klein, Markus AU4 - Holtmannspötter, Jens AB - The additive manufacturing of electronics allows the printing of complex structures, such as antenna matrixes, motors, and system-in-packages, directly into a three-dimensional shape. This freedom enables new design approaches for various applications in different fields. The additive manufacturing system under investigation uses inkjet technology, which is capable of applying a conductive and a non-conductive ink layer-by-layer at the desired places. This layer-by-layer approach creates a rough outline of the conductive material that negatively impacts high-frequency signal transmission. This article proposes a blockwise printing strategy to smooth the contours of the conductive material, enhancing its high-frequency properties. The evaluation of representative geometries, resembling printed samples that can be obtained using a custom slicing software, showed that the blockwise strategy reduced electrical losses by a factor of two compared to the conventional layer-by-layer approach. Numerical simulations demonstrated that this method achieves improved impedance performance in materials with low-loss tangents. These findings highlight the potential of alternative additive manufacturing strategies to optimize high-frequency performance in electronic devices.
