3-D Printed Horn Antennas and Components Performance for Space and Telecommunications

In this work, a study of the performance of several antennas and components, manufactured using an accurate stereolithography three-dimensional printer and resin for maximum accuracy and detail, is carried out. Electroless plating of the components to cover the pieces with a thick copper layer to improve their mechanical resistance is undertaken. Several SatCom horn antennas and components are designed, manufactured, and tested. A detailed study of a spline horn antenna and a filter is covered. These results are compared to the metallic lathe manufactured versions. Conclusions are derived from these tests, which are useful to improve additive manufactured components in future versions.
