“…Different 3D-printing technologies can be used to produce electromagnetic devices [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. In Farooqui et al and Fenn et al [ 1 , 2 ], the Fused Deposition Modelling (FDM) technology has been used to build a cross-polarized (CP) microstrip fed patch antenna in Farooqui et al [ 1 ] and a conformal antenna array in Fenn et al [ 2 ], respectively.…”

“…In Kaddour et al [ 5 ], a Selective Laser Sintering (SLS) process has been used to polymerize polycarbonate (PC) and ABS in other to develop a dual-polarized unidirectional wideband antenna, with metallic parts obtained with electroplating. In Gjokaj et al [ 6 ], a Vivaldi antenna operating in the Ku band has been described as well as its manufacturing process, the so-called Polyjet 3D-printing. In this case, the metallization has been created with a first deposition by sputtering of a Titanium and Copper compound, then used as a base for an electroplating process.…”

In this work, the application in Radiofrequency Identification (RFID) of different additive manufacturing (AM) 3D-printing technologies is discussed. In particular, the well-known Fused Deposition Modeling (FDM) technology is compared with the promising Digital Light Processing (DLP), which is based on the photopolymerization of liquid resins. Based on the research activity of the authors on this topic, a brief introduction to the fundamentals of 3D-printing in electromagnetics as well as to the different applications of both FDM and DLP in realizing Radio Frequency (RF) devices, is firstly given. Then, a comparison of the two technologies is deeply faced. Finally, after evaluated the rugosity of substrates produced with both techniques to verify the potential impact on the design of electromagnetic structures, the two techniques are both exploited for the realization of the dielectric parts of a tunable RFID tag with unconventional shape. It consists of two elements interlinked one each other. The movement between them enables tuning of the resonance frequency as well as the impedance of the antenna. Despite the differences in terms of losses, rugosity, resolution, and dielectric constant, both techniques guaranteed satisfactory values of tag sensitivity, maximum reading range, and tunability. Nevertheless, the careful analysis of the results proposed at the end of the paper suggests how the selection of one technique over the other must be taken considering the specific application constraints.

“…Also, for the Ku-band, the design, production and measurements of an Ultra-Wideband (UWB) Vivaldi antenna were presented in [81]. The antenna's structure was printed with the material VeroWhitePlus [68], sputter-deposited with Ti and Cu, and followed by electroplating with copper to reduce conductor losses.…”

“…Bearing in mind what was mentioned earlier, 3D printing is a potential solution for the antennas production, since [55], [57], [82], [83], [89], [94] PLA Dielectric r = 2.7 tan δ = 0.008 @ 1 MHz [140] [72], [76], [90], [95], [101], [122] Vero White Dielectric r = 2.97 tan δ = 0.0285 @ 1.5 GHz [141] [67], [71], [81], [82], [ [127], [128], [129], [130], [138] it allows the rapid development of compact, robust and lightweight objects at a low cost that can be implemented in sensors for monitoring the everyday life.…”

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.

“…However, this approach is limited by ink conductivity, which besides being an expensive supply can degrade antenna efficiency. On the other hand, [47] shows another use of AM in developing a UWB antenna. An interesting approach to metallization is carried out by sputtering which creates a thin copper (Cu) layer followed by electroplating to achieve a thick Cu layer.…”

This paper presents the design, manufacture, and experimental validation of a novel 3-D pixel antenna with volume-filling characteristics, and the design is based on our Method of Moments (MoM) solver that is efficiently coupled with a global/local optimizer for tailoring the antenna shape and concurrently selecting the location of the feeding port and shorting straps. The design, aimed at operating in the ISM bands of 2.45 GHz and 5.8 GHz, has dimensions under one-tenth of wavelength at the lowest frequency of operation. The optimization results are cross-validated using a commercial full-wave simulator, with a deviation of the reflection coefficient across the operating bands within 3%, showing also a high antenna efficiency of 99.6% and a gain of 1.06 and 4.53 dBi at the matching frequencies, with radiation patterns predominantly oriented towards the top hemisphere. Tolerance and parameter sensitivity studies were also performed. A scaled-up prototype of the antenna was built at a very low cost using standard additive manufacturing techniques, featuring a very good agreement between simulation and measurements, which proves the feasibility of this new kind of complex shape antennas in further applications where compact internal antennas are required.
