| Description | Warwick have utilised commercial polymeric and metallic 3D Printing technologies to support the manufacture of communication antennas and array antennas. A range of 3D Printing technologies have been employed, including polymer Material Jetting (followed by metallisation), Vat Polymerisation, and metal laser Powder Bed Fusion (PBF), with the advantages and disadvantages of each approach being identified. Material Jetting and Vat Polymerisation provide good (smooth) surface quality and good resolution (detail) but the secondary metal coating results in some loss in antenna performance. Direct metal PBF offers highly conductive metallic antenna components but at reduced accuracy and higher surface roughness, but improved performance over their polymer counterparts.Measurement results of the two antenna prototypes are compared. It is shown that 3D Printing technologies can produce wideband high-gain antennas at 140 GHz having a 14.2% bandwidth with a maximum gain of 15.5 dBi. Warwick have utilised the Vat Polymerisation 3D Printing technique for the manufacture of high dielectric constant (interact with electromagnetic waves strongly) ceramic-polymer composites that, although not directly applied here, have the potential to provide impact in future antenna design and manufacture within the consortium. |
| Exploitation Route | The use of direct and indirect 3D Printing methods to manufacture antennas and antenna arrays that offer good performance can be exploited by many sectors where lower cost communication systems are required. Industry can adopt this now proven approach to novel antenna designs. The proven ability to 3D Print structures using polymer-ceramic high dielectric composites can be exploited by EM modellers and EM system designers to create novel EM modification devices such as waveguides, lenses, reflectors and metamaterials. |
