3D printing is becoming increasingly popular due to its convenience, ease of use, and low cost. Companies such as Ford, General Electric Aviation, and many others are using 3D printing for rapid prototyping before investing time and money in volume manufacturing. However, development in 3D‐printed microwave antennas has remained limited. In this study, a parametric analysis of solely (one step process) 3D‐printed 5.8 GHz patch antennas using commercially available conductive and dielectric materials is presented. Effects of tool path and layer resolution on the substrate material's complex permittivity and radiative material's conductivity are explored. These antennas will utilize commercially available conductive PLA filament (Black Magic) based on graphene as the material for the radiating elements and ground plane. Dielectric PLA will be used in place of the substrate.
