Özet

Additive Manufacturing (AM) is a rapidly developing set of methods with lots of benefits. This technology promises fast, cheap and lightweight fabrication for the antennas and waveguides. Different AM technologies such as Fused Filament Fabrication (FFF), Stereolithography (SLA), Material Jetting and Powder Bed Fusion are used to fabricate antennas operating at various frequency bands and provide desirable results. To test the feasibility of the AM technologies for antenna manufacturing, a specific antenna has been modeled and fabricated via FFF and SLA type of 3D printers. The fabricated antennas are coated with copper spray and aluminum and the radiation parameters are measured. The accordance of the measurement results with the simulations and CNC machined pair have been inspected.
