Design and Analysis of 3D Printed Slotted Waveguides for D-Band
using Stereolithography and Electroless Silver Plating
This work demonstrates the feasibility of entirely
additively manufactured slotted waveguides in combination with
an electroless silver plating process for applications in the
D-Band frequency range. Design rules are adjusted towards
the requirements at 110-170 GHz and analyzed with respect to
the limitations of conventional desktop SLA- and DLP printers.
Measurements obtained in this work reach attenuation levels in
the order of 20-35 dB/m, hence keeping up with conventionally
manufactured waveguides. Furthermore, it is shown, that the
slotted waveguide behaves similar to a conventional waveguide
by comparison with simulation models.
