“…A direct write (DW) technology, aerosol jet printing (AJP) is well suited to print conductive and dielectric traces for RF applications [31,32] because it can be used to print a wide range of inks with viscosities from 1 to 1000 cps. Moreover, the relatively large stand-off distance (3-5 mm) offers advantages for conformal surface and complicated devices [33].…”

In this paper, we report the use of additive manufacturing methods to fabricate a high aspect ratio, low noise amplifier (LNA) for a handheld active sensor device operating at up to 1 GHz. The new form factor LNA incorporates a modification of a square-shaped commercial off-the-shelf (COTS) LNA into a 5:1 aspect ratio device without a loss in RF performance. For rapid prototyping, we employ both subtractive and additive manufacturing technologies, such as milling, extrusion-based syringe printing, and aerosol jet printing techniques to fabricate both small form factor and high aspect ratio devices. The 5:1 aspect ratio LNA demonstrated a 20% smaller form factor, a gain of 25 dB, and an NF less than 3 dB over an operating frequency range up to 1 GHz, comparable to the COTS LNA. Design, simulation, and experimental results are given to highlight the advantages of 3D printed hybrid electronic technology over the conventional PCB fabrication method for rapid prototyping of RF electronic devices.

“…To solve this integration issue, a ramp transition was introduced from a dummy chip. These kinds of transitions have the potential to provide a wide bandwidth over the other 1215. https://doi.org/10.1017/ 1212 , conventional solutions [11]. Figure 2(a) shows the transition concept where a chip can be placed on a substrate and a ramp can be made with a dielectric material starting from the edge of the chip to the substrate.…”

Main aim behind this study is to utilize 3D printing technique for designing and fabrication of a flexible wideband Vivaldi antenna for the upcoming 5 G systems. Frequency bands starting from 24 up to 65 GHz are receiving particular attention as they have potential for both high data rate communications and high-resolution radar applications. A Vivaldi antenna is used for its very wideband properties and planar design. The radiating structure covers a bandwidth of 25–65 GHz for a match better than −10 dB and demonstrates reasonably high gain and efficiency performance. The simulated radiation efficiency of the antenna remains above 90% for the entire bandwidth. Hence, the main advantage of this approach is that wideband or switched transceivers for future 5 G communications can be integrated using this concept without the need of complex matching networks.

“…The Ag ink from Clariant has a sheet resistance of 0.024 Ω/Square and the Au ink from UTDots has a sheet resistance of 0.129 Ω/Square. Both inks have been demonstrated in printed FHE devices such as strain gauges, capacitor electrodes, interconnects and coplanar waveguide (CPW) lines [13][14][15][16][17]. An Optomec AJ300 aerosol jet printer was used for this work.…”

The effects of atomic oxygen (AO) in low earth orbit and the physical effects of space launch on printed materials were studied for aerosol-jet printed Au and Ag through a 6 month exposure period on the Materials International Space Station Experiment (MISSE). RF and DC test platforms were designed for two printed electronics-compatible substrates (Rogers CLTE-XT and Ferro L8) to assess the amount of degradation caused by AO exposure in space. A passivation layer of CORIN-XLS applied over the printed metal traces was also studied for its effectiveness. Both bare and passivated test structures of printed Ag and Au traces were exposed to low earth orbit on the 10th MISSE mission. The effects of AO and the 6 month space exposure on the samples are reported here.
