3D Printing of Ka band Orthomode Transducers

In this paper, the advance of an on-going research activity jointly developed by CNR-IEIIT, IIT and Politecnico di Torino in the design and SLM manufacturing of high performances microwave devices is reported. In particular, two prototypes of Ka-band Orthomode Transducers, based on a novel AM-oriented layout, are presented. All the component building blocks, such as, coupling junction, bends and twists are integrated in a single mechanical part suitable for 3D printing.
