This study proposes a compact dual-polarised directive radiator whose complex prototyping is enabled by additive manufacturing. In addition to monolithic implementation, stereolitography followed by metal coating, it also provides high radio-frequency performance, low cost and low weight. Dual-channel simultaneous operation is supported thanks to the integration of an orthomode transducer within the...
This paper presents a set of additive manufactured (AM) monolithic waveguide-based feed-chain and antenna components, namely a Ku-band diplexer, a Ka-band dual-polarized directional antenna and W-band straight waveguides. These components provide representative examples of the current capabilities of AM technologies. Examples are provided over a large frequency spectrum and for diverse applications...
In this paper an additive manufactured (AM) W-band monolithic feed chain is presented. The feed chain, which consists of a corrugated horn antenna and a turnstile orthomode transducer (OMT), operates over the entire W-band (75–110 GHz) and fulfills typical RF specifications for a chosen space-borne radiometer application (RL > 20 dB, IL < 1 dB and Xpol < −30 dB). Both the OMT and the horn...
