“…A Q-band (33-50 GHz) Luneburg lens was printed by Nguyen in 2010 [17], with 55-65 GHz bandwidth and 21 dBi gain. A W-band corrugated horn and waveguide were printed by SLA using UV-polymer in 2011 [18]. They were printed in split pieces and metal plated in postprocess.…”

The 3D printing technology is catching attention nowadays. It has certain advantages over the traditional fabrication processes. We give a chronical review of the 3D printing technology from the time it was invented. This technology has also been used to fabricate millimeter-wave (mmWave) and terahertz (THz) passive devices. Though promising results have been demonstrated, the challenge lies in the fabrication tolerance improvement such as dimensional tolerance and surface roughness. We propose the design methodology of high order device to circumvent the dimensional tolerance and suggest specific modelling of the surface roughness of 3D printed devices. It is believed that, with the improvement of the 3D printing technology and related subjects in material science and mechanical engineering, the 3D printing technology will become mainstream for mmWave and THz passive device fabrication.

“…MMW rectangular waveguides, feed horns, filters and other hollow passive components exhibit high aspect ratio channels that can be challenging to metallize. Previous studies relied on the splitblock technique where the component is split into two or more pieces that are separately coated and subsequently aligned and assembled [2]. This is an expensive and time-consuming process that often leads to degraded performance.…”

Abstract-A stereolithography-based manufacturing process for monolithic high aspect ratio components for mm-wave and sub-mm-wave applications is demonstrated. A 25 mm long straight waveguide and a diagonal horn antenna, both for the WR-3.4 band (220-330 GHz), are manufactured and characterized. The waveguide is found to exhibit transmission losses close to the theoretical minimum for Cu, and the performance of the diagonal antenna in terms of cross-polarization and directivity matches closely a metallic split-block reference antenna. These results confirm the high surface quality and mechanical accuracy of the employed 3D printing and plating techniques and thus validate the process for rapid manufacturing of monolithic components up to 330 GHz.

“…Recently, 3D printing technology has been attempted for horn antenna fabrication. For example, Timbie reported a dielectric 3D-printed, W-band (75-110 GHz) corrugated horn antenna, which was first printed in split pieces, then metal plated and finally assembled [6]. Chieh proposed a Ku-band (10-16 GHz) corrugated horn antenna by dielectric 3D printing [7], which went through the same process as [6].…”

Featured Application: This paper introduces the application of metallic 3D printing technology to fabricate K-band-stepped, double-ridged horn antennas. The proposed antennas feature comparable performance with commercial counterparts with lower cost and a reduced turnaround time.Abstract: This paper presents K-band-stepped, double-ridged square horn antennas fabricated by metallic 3D printing technology in copper (85% copper and 15% stannum) and aluminum alloy (89.5% aluminum, 10% silicon, and 0.5% magnesium). Compared with the popular dielectric 3D-printed horn antenna, the metallic counterpart features better mechanical robustness in terms of material. Moreover, the metallic horns are printed in one piece in one run, different from the dielectric horns that are printed in split pieces and electroplated, they simplify the process and thus result in reduced cost. The agreement between the simulation and measurement results verified the antenna's performance. Both the 3D-printed copper and aluminum alloy antenna have an impedance bandwidth across the K-band, with a maximum gain of 13.23 dBi @ 25 GHz and 13.5 dBi @ 24 GHz, respectively. The metallic, 3D-printed horn antennas are preferable alternatives to replace traditionally-fabricated antennas.
