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.

Grooves around aperture antennas are known to be instrumental in obtaining directive antenna patterns. The shapes of the grooves are often restricted to rectangular or triangular due to manufacturing difficulties in traditional metal machining, and because of this reason, the effect of groove shape on antenna performance is often overlooked. The aim of this study is to analyze different groove shapes with the help of additive manufacturing. Waveguide slot fed, dual cavity aperture antenna with grooves is designed and the effect of groove shapes on antenna performance is studied at Ku band. Two antennas with and without grooves are built using 3D printing technology. Measured antenna performance reveals 5 GHz bandwidth covering 10 to 15 GHz for Ku-band satellite communications and part of the X-band applications. Proposed antenna achieves 13.25 dBi peak gain at 14 GHz and the gain is better than 11.25 dBi over the entire Ku-band uplink and downlink frequency bands. K E Y W O R D S

“…eyond its initial success enabling cost-effective free-form prototyping, additive manufacturing (AM) allows for enhanced performance within a single monolithic component, thus consolidating its relevance for the RF industry [1] - [4]. Recent examples evidence the possibility to upgrade the capabilities of an RF component by increasing its complexity without impacting the AM process [5], [6]. The present contribution intends to extend this principle to the design of directive antennas for inter-satellite links (ISLs) in smallsatellite constellations.…”

This article investigates the potential of additive manufacturing for the fabrication of complex antenna geometries with enhanced performance at K-band. Stereolithography is here used to 3D-print a novel topology of dual-polarized leaky-wave antenna that allows for the control of its aperture illumination both in phase and magnitude. The antenna consists of a modulated triple-ridge square waveguide perforated on its top wall with crossed slots of different sizes. An orthomodetransducer is integrated within the structure for dual-mode operation. Monolithic implementation of this compound threedimensional structure is only possible thanks to additive manufacturing. In addition, low weight and compactness are attained comparing to classical milling. The present proposal is validated through the manufacturing of a low sidelobe levels prototype suitable for intersatellite links. The corresponding measured results are in very good agreement with full-wave predictions.
