“…In the former case, the conductive parts have been obtained using copper adhesive tape, while in the latter a copper electroplating process has been carried out. In Heirons et al and Mirmozafari et al [ 3 , 4 ] a CP patch antenna and a linear array have been described as well, but this time the adopted manufacturing technology has been the Stereo Lithography (SLA) 3D-printing. In these cases, the conductive parts have been realized with inkjet printing in Heirons et al [ 3 ] and with an electroplating process in Mirmozafari et al [ 4 ].…”

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.

This paper introduces the first fully 3-D printed tunable microwave subsystem, consisting of 26 circuit elements. Here, a polymer-based 3-D printed Ku-band 4-element steerable phased-array antenna with fully integrated beam-forming network is demonstrated. Polyjet was adopted for fabricating the main body of the subsystem, as it is capable of producing a geometrically complex structure with high resolution over a large volume. Low-cost fused deposition modeling was chosen to manufacture the dielectric inserts and brackets for the phase shifters. The measured radiation pattern revealed that the phased-array antenna subsystem has total beam steering angles of 54 • and 52 • at 15 GHz and 17 GHz, respectively. Excellent input return loss behavior was observed across the optimum operational frequency range of 15 to 17 GHz, with a worst-case measured return loss of 12.9 dB. This work clearly shows the potential of using 3-D printing technologies for manufacturing fully integrated subsystems with complex geometric features.

Novel dielectric rod antennas (DRAs) are proposed in this article with the merits of low‐cost and easy fabrication. The printed log‐periodic dipole array is introduced as a feeding source. The cylinder‐shaped rods are perforated with air holes of different shapes and sizes to vary the spatial effective permittivity distribution, which mimics the arrangement of traditional multilayer rod antennas. Comparing with traditional multilayer rods, the proposed DRAs use only a single type of dielectric material while achieving similar bandwidth and gain increment performances. Thanks to 3D printing technology, the proposed antennas can be designed with much increased flexibility. Meanwhile, the fabrication cost and complexity can be drastically reduced, since only a single type of dielectric material is needed. Furthermore, both rod antennas were fabricated and measured. The proposed rod antennas have peak gains of 13.32 to 13.45 dBi, 1‐dB gain bandwidth of 25.2% to 26% and average gains of 12 to 12.5 dBi.
