Abstract

In this work, an additively manufactured 3dB hybrid coupler is presented. While the geometrical structure is generated by an SLA printer from UV curable photopolymer resin as one single part, conductive coating is provided by an electroless silverplating process. The utilized slotted waveguide approach improves the solvent flow during metal plating and therefore enables the fabrication of complex waveguide struc- tures. Measured imbalance between the through and coupling port stays below 1.5dB over the entire E-Band, while the respective phase difference ranges only between 87◦ and 91◦ degrees despite the challenges of additive manufacturing in such frequency regions.
