Herein, by using 3D printing technology and data‐driven surrogate model‐assisted optimization method, design of a ceramic material‐based nonuniform nonplanar microstrip filter is taken into the consideration in a computationally efficient and low‐cost manner. For this aim, 3D EM model of the proposed design had been used for generating training and validation data sets. Then commonly used state‐of‐the‐art regression algorithms had been used for creating accurate and fast surrogate models to create a mapping between inputs of the model and outputs of the unit element design. After that, Grey Wolf Optimization algorithm had been used for design optimization of a bandpass filter. Then, via the use of 3D printer, the optimally designed filter had been prototyped and its performance characteristics are measured. As a result, by using 3D printer technology, ceramic material, and the proposed method, design optimization of nonuniform nonplanar microstrip filter can be achieved in a computationally efficient way.

“…Following the conductive filaments, two possible solutions available on the market are the Protopasta filament [120], a conductive PLA with a conductivity of σ ≈ 6.67 S/m, and the BlackMagic 3D graphene-enhanced PLA filament [121], with a conductivity of σ ≈ 166 S/m. The authors in [122] selected the Black Magic 3D filament to manufacture a 5.8 GHz patch antenna due to its higher conductivity compared with Protopasta. To build the antenna, a Lulzbot Taz 5 dual print head 3D printer with a printing resolution of 0.1 mm, [123], was used in order to simultaneously print the substrate in PLA and the conductive patch and ground plane of the antenna in BlackMagic.…”

printing technology is an area of research that has received great attention in the last decade and it is pointed out by many as the future of manufacturing. 3D printing can be described as an additive process that creates a physical object from a digital model, depositing materials layer by layer. The ability to quickly produce complex structures at a reduced cost and without wasting materials is the main reason why this additive manufacturing technique is increasingly being used instead of conventional manufacturing processes. 3D printing has been applied in several scenarios, including automotive, maritime and construction industry, healthcare, as well as in the antenna research field. This paper reviews the current state-of-the-art of 3D printed antennas. Firstly, an overview of 3D printing technology is presented and then a vast number of 3D printed antennas, categorized by their construction process, are described. Finally, the main advantages and some of the limitations of using 3D printing technology in the construction of Radio Frequency (RF) structures are presented.

“…Advancement in printing equipment enables printing microwave devices with complex geometries using a variety of materials. These merits have made 3‐D printing an alternative pathway for rapid prototyping of RF and microwave passive components, such as waveguides, 2,3 filters, 4‐6 magic‐T, 7 antennas, 8‐14 and so on. The three most popular 3‐D printing techniques in the microwave field are fused deposition modeling (FDM), stereolighography (SLA) and selective laser sintering or melting (SLS/SLM) 15 .…”

In this article, two Ka‐band (26.5‐40 GHz) waveguide attenuators designed for three‐dimensional (3‐D) metal printing are presented. These designs are based on long waveguides with elliptical cross‐sections, so that the waveguide structure can be self‐supported during printing. Bended waveguide and helical waveguide are utilized by the two attenuators, respectively, to achieve reduced overall sizes. The attenuations are fixed, however, these can be altered by varying the length/height of waveguides. The limitation of 3‐D metal printing process on surface roughness is also used to provide attenuation. Therefore, the proposed attenuators can cope with printing process with relatively poor surface finish. The prototype designs are fabricated using a metallic selective laser melting (SLM) process and are measured to have good electrical performance across the full waveguide band. The measured attenuation values are in the range of 3.7 to 6.3 dB for the bended waveguide attenuator and 4.3 to 6.3 dB for the helical waveguide attenuator. Both attenuators are measured to have a good return loss (S11 < −20 dB) across the whole Ka‐band. This demonstrates that 3‐D metal printed attenuators could be an attractive alternative to the conventional designs based on absorbing materials, particularly for applications demanding high powers.
