Abstract

This work proposes a fabrication approach for 3D printed waveguide paths
based on a combination of an optimized electroless silver plating
process with a waveguide-specific design rule for general metal plating
by introducing large scale non-radiating slots into the broad and narrow
waveguide walls with a periodicity shorter than quarter of the guided
wavelength. Experimental fabrication of straight sections of the
proposed slotted waveguide with various gap dimensions yields an optimum
gap size as result of a trade-off between silver plating quality and
leakage losses through the sidewall gaps Moreover, a successful
practical application of the proposed approach is presented in terms of a
3D printed multiple bend waveguide interconnect in three different
space dimensions which imposes a complex task for conventional
manufacturing techniques due to the need of multiple cutting planes for
split block assembly. The proposed approach benefits of low cost,
moderate handling effort and independence of the concrete geometry to
manufacture making it therefore especially interesting for distribution
and feeding networks in the context of rapid prototyping, automotive and
space related applications.
