摘要：

In this letter, an additively manufactured 3 dB hybrid coupler is presented. While the geometrical structure is generated by a stereolithography (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 structures. Measured imbalance between the through and coupling ports stays below 1.5 dB over the entire E-band, while the respective phase difference ranges only between 87 degrees and 91 degrees despite the challenges of additive manufacturing in such frequency regions.
