“…For these reasons, in the open literature, 3D printing based on material extrusion is mainly employed to build only the dielectric structure of the antenna, falling back on alternative solutions to provide the metallisation [4–27]. Many types of antennas operating at very different frequencies and many techniques to realize the conductive parts have been adopted in these works.…”

Additive manufacturing (AM) 3D‐printing technology is increasingly bringing benefits even in electromagnetics, with interesting prospects of application. Apart from the use of additive manufacturing for realising dielectric components of suitably shaped antennas, the ambitious target is, undoubtedly, the fully 3D realisation of radiofrequency and microwave circuits as well as radiating structures, including, therefore, conductive parts. In this regard, 3D‐printable filaments with interesting conductive properties are being produced. However, their rigorous conductivity characterisation is still missing, making it difficult to estimate the real behaviour of the final 3D printed electromagnetic device. To fill this gap, the conductivity of one of the most interesting conductive filaments, named Electrifi, is first experimentally evaluated in a frequency range as large as 0.72–6 GHz, accounting also for its roughness. Then it has been validated by designing, realising, and testing three fully 3D‐printed antennas. Specifically, two bow‐tie antennas, operating at 2.8 and 4 GHz, respectively, and an ultrawideband antenna, borrowed from the existing literature, operating between 1 and 7 GHz. The good agreement between simulated and measured results demonstrates the reliability of the performed electrical conductivity characterisation, even in the design of efficient radiating structures entirely realised with thermoplastic materials with copper nanoparticle additives.

“…Interest in LWAs has endured since it was first discovered. Various types of LWAs have been developed, such as substrate integrated waveguide (SIW)-LWA using line sources for endfire radiation [10], SIW-LWA, such as the butterfly [11], new reconfigurable 1-D LWA Fabry-Perot [12], multilayer SIW composite right left-handed (CRLH) dependent on LWA [13], SIW double periodic CRLH LWA [14], circularly polarized half-mode SIW (HM-SIW) [15], LWA based on SIW with transverse slotted rectangular waveguide [16], novel 3D half width microstrip based on LWA [17], HW-MLWA with stub loaded for beam steering [18], LWA with loaded shorted via [19], and full width microstrip LWA wideband for two symmetrical beam scanning [20]. However, most studies on LWA have focused on continuous beam scanning without focusing on how the bandwidth can be increased to obtain a wide scanning range.…”

This paper presents a new technique to enhance impedance bandwidth of single layer half width microstrip leaky wave antenna (HW-MLWA) with continuous main beam scanning. The enhancement is realized by etching four circular slots on the radiation element. Two of the circular slots are placed close to the feed port, and the others are close to the matching load. The wide main beam scanning is between +12 • and +70 • when operation frequency sweeps between 4.3 GHz and 6.5 GHz. A comparison between the Uniform HW-MLWA (reference) and the proposed HW-MLWA with circular slots is provided to study the effectiveness of the added circular slots. The proposed HW-MLWA is fabricated and tested. The measured impedance bandwidth is 49.9% (4.28 GHz to 7.13 GHz) with peak gain 10.31 dBi at 5 GHz, hence the proposed antenna can be considered as a suitable candidate for C-band applications.

Antenna Design Using Modern Additive Manufacturing Technology: A Review

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.
