“…As of 2014, however, 11% of manufacturers have switched to 3D‐printed parts for volume production . 3D printing has also been employed in the development of circuit boards, however, production of such electronics has required a 2‐step process where (1) a 3D shape is first printed and then (2) a conductive liquid/ink is deposited onto the shape . In the realm of 3D‐printed electrical devices, the production of microwave antennas via 3D printing has also seen innovations evident by the development of specialized 3D printers specifically for electromagnetic devices .…”

“…In the realm of 3D‐printed electrical devices, the production of microwave antennas via 3D printing has also seen innovations evident by the development of specialized 3D printers specifically for electromagnetic devices . Various electromagnetic devices have been developed using 3D‐printing methods include transmission lines, microstrip filters, sensors, waveguides, resonators, antenna pads, and frequency selective surfaces . So far these devices are fabricated using the 2‐step process requiring not just 3D printers, but specialty extrusion and curing methods for the conductive inks .…”

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.

“…There has recently been a growing interest for additive manufacturing in the production of high performance and monolithic microwave passive components with production time and cost competitiveness . The production of rectangular waveguide T‐junction with fused deposition modeling (FDM) technique is a good alternative to traditional methods in terms of reduced weight, flexible applicability, and being monolithic for complex geometry.…”

Three‐dimensional (3D) printed rectangular waveguide T‐junction is presented with in‐phase and equal power division by means of iris and septum at 10–15 GHz frequency range to use the waveguide feed network for array antenna. The proposed T‐junction structure is designed and fabricated with 3D printing, as novelty, that is a good alternative to traditional methods in terms of reduced‐weight, cost, flexible applicability, and being monolithic for complex geometry. After making the skeleton of T‐junction from acrylonitrile butadiene styrene, metal plating process is applied over the all surfaces with copper. Transmission and reflection characteristics and electric‐field distribution of the structure are obtained with CST Microwave Studio software. Qualitative agreement is obtained between measurement and simulation with ∼7 dB shift and that shift is because of high precision and low surface roughness on 3D printed junctions. Unlike studies in the literature, the proposed study provides two points, as a novelty: First is that the fabrication of rectangular waveguide T‐junction with 3D printing is made. Second is that the return loss of T‐junction is improved by changing the geometry of iris and septum.
