“…However, the antenna manufacturing process requires additional effort, since the structure had to be divided into 3 sub-arrays due to the limited size of the utilized SLA printer. This 3D printing technique was also used to develop a Yagi-Uda Loop antenna operating at 2.45 GHz [59]. The material used was a resin (FormLabs Durable [60]) with a dielectric constant of 2.78 and a loss tangent of 0.06.…”

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.

“…Despite presenting proper gain and good efficiency, the construction process makes this strategy prohibitive, because it is very cumbersome and a spray coating is necessary to apply. One of the main limitations of 3D printing is the ability to produce metallic elements [ 10 ]. In this sense, a liquid metal alloy was used to produce a Yagi-Uda Loop Antenna, operating at 2.45 GHz using a low-cost manufacturing process.…”

With the rise of 5G, Internet of Things (IoT), and networks operating in the mmWave frequencies, a huge growth of connected sensors will be a reality, and high gain antennas will be desired to compensate for the propagation issues, and with low cost, characteristics inherent to metallic radiating structures. 3D printing technology is a possible solution in this way, as it can print an object with high precision at a reduced cost. This paper presents different methods to fabricate typical metal antennas using 3D printing technology. These techniques were applied as an example to pyramidal horn antennas designed for a central frequency of 28 GHz. Two techniques were used to metallize a structure that was printed with polylactic acid (PLA), one with copper tape and other with a conductive spray-paint. A third method consists of printing an antenna completely using a conductive filament. All prototypes combine good results with low production cost. The antenna printed with the conductive filament achieved a better gain than the other structures and showed a larger bandwidth. The analysis recognizes the vast potential of these 3D-printed structures for IoT applications, as an alternative to producing conventional commercial antennas.

“…For example, metallic parts are always problematic to create and often need some further manufacturing process to be prototyped. They can be printed, even for high-frequency applications, but using most complex and costly devices As for Vat-polymerization 3D printing technologies, in [6], an interesting hollow structure has been printed with SLA to realize a Yagi-Uda loop antenna utilizing liquid metal to fill the microfluidic channels; in [7], an X-band horn antenna fabricated by an SLA 3D printer in barely 3 h has been described.

One of the most promising and exciting research fields of the last decade is that of 3D-printed antennas, as proven by the increasing number of related scientific papers. More specifically, the most common and cost-effective 3D printing technologies, which have become more and more widespread in recent years, are particularly suitable for the development of dielectric resonator antennas (DRAs), which are very interesting types of antennas exhibiting good gain, excellent efficiency, and potentially very small size. After a brief survey on how additive manufacturing (AM) can be used in 3D printing of antennas and how much the manufacturing process of DRAs can benefit from those technologies, a specific example, consisting of a wideband antenna operating at 2.4 GHz and 3.8 GHz, was deeply analyzed, realized, and tested. The obtained prototype exhibited compact size (60 × 60 × 16 mm3, considering the whole antenna) and a good agreement between measured and simulated S11, with a fractional bandwidth of 46%. Simulated gain and efficiency were also quite good, with values of 5.45 dBi and 6.38 dBi for the gain and 91% and 90% for the efficiency, respectively, at 2.45 GHz and 3.6 GHz.
