“…This concept of using unique features on each unit is prohibitively costly when using traditional photographically, but easy to integrate on an AM production process with no added cost. The manufacturing process of RF front-end devices has been benefiting from additive manufacturing (AM) techniques and their capabilities, such as rapid prototyping and conformal designs, that traditional manufacturing cannot achieve [27]. The underlying concept of AMEF is to intentionally modify the fingerprint of RF transceivers and leverage its uniqueness to enhance the security of wireless systems.…”

Physical layer security is increasingly being exploited as a technique to enhance the security of wireless communications. Wellknown hardware security techniques leverage unintended manufacturing process variations or fixed unique hardware structures in the semiconductors for identification of different copies of an RF system. The fundamentally different concept of engineering a unique fingerprint for each antenna produced, by leveraging additive manufacturing, is presented in this work. To the best of the author's knowledge, this is the first application of the concept of radio frequency (RF) fingerprint engineering using additively manufactured (AM) antennas for hardware-based security mechanisms. AM engineered fingerprints (AMEF) are based on intentional features added to antenna's geometries using 3D printing, enabling more accurate signal source identification and classification. Such unique features per unit produced would be prohibitively costly by using traditional photolithographic processes. The AMEF concept is validated using AM right hand circularly polarized (RHCP) truncated corner probe fed (TCPF) patch antennas and a testbed setup with software-defined radios and MATLAB implementations to create, transmit, receive, and prepare a convolutional neural network (CNN) to classify the transmitted raw I/Q data of Wi-Fi signals (IEEE 802.11). The AMEF technique greatly improves the physical layer security performance limitations in large-scale applications where the features of the devices can overlap, at a low-cost and low production time impact, and it allows the use of the antenna features for both individual and type classification and identification of RF sources.

“…The literature reveals incremental advancements in reflectarray technology, including efforts to utilize inkjet printing for antenna fabrication, explore flexible substrates for enhanced mechanical versatility, and apply origami principles for deployable structures [1][2][3][4][5][6][7]. However, existing studies typically address these aspects in isolation, focusing on either the manufacturing technique, the substrate material, or the deployment mechanism without fully integrating these components into a singular, cohesive design.…”

This paper presents an innovative method for fabricating reflectarray antennas using inkjet printing technology on flexible substrates, markedly enhancing integration and manufacturability compared to traditional PCB methods. The technique employs inkjet printing to deposit conductive inks directly onto a flexible polyethylene naphthalate (PEN) substrate, seamlessly integrating feed and reflectarray components without complex assembly processes. This streamlined approach not only reduces manufacturing complexity and costs but also improves mechanical flexibility, making it ideal for applications requiring deployable antennas. The design process includes an origami-inspired folding of the substrate to achieve the desired three-dimensional antenna structures, optimizing the focal length to dimension ratio (F/D) to ensure maximum efficiency and performance. The feed and the reflectarray geometry are optimized for an F/D of 0.6, which achieves high gain and aperture efficiency, demonstrated through detailed simulations and measurements. For normal incidence, the configuration achieves a peak gain of 9.3 dBi and 48% radiation efficiency at 10 GHz; for oblique incidence, it achieves 7.3 dBi and 40% efficiency. The study underscores the significant potential of inkjet-printed antennas in terms of cost-efficiency, precision, and versatility, paving the way for new advancements in antenna technology with a substantial impact on future communication systems.

“…However, these designs focus on small aperture FPRs stowed on the exterior of the CubeSat buses. In [24], a large aperture (64.2 cm × 64.2 cm) origami-based deployable FPR was presented. However, the stowed dimensions of the FPR (13.5 cm × 10.0 cm × 6.2 cm) prevent it from being stowed within the volume of a standard CubeSat unit (1U = 10 cm × 10 cm × 10 cm).…”

Traditional high-gain antennas, like parabolic reflectors and phased arrays, are challenging to implement on small satellites (SmallSats) due to their reduced volume when stowed for launch. Therefore, a deployable volume-efficient Miura-ori (VEMO) reflectarray aperture is presented that achieves high gain (35.3 dBi) and high volume efficiency (96%). The design is based on a modified Miura-Ori origami folding pattern that allows for ultra-high volume efficiency and simple deployment. In its stowed state, the aperture fits in a cuboid volume (8.0 cm × 8.0 cm × 2.5 cm) that occupies just 16% of the volume of a 1U CubeSat. The aperture is deployed by releasing stored energy from strategically placed neodymium magnets in the magnetic longitudinal offset (MaLO) hinge system. The aperture has a large reflecting surface area (24.8 cm × 24.8 cm) that is stabilized by the MaLO hinges. The antenna operates in the K a -band (38 GHz), and provides low side lobe level (-17.5 dB), high cross-polarization discrimination (37.1 dB), and acceptable efficiency (27.4%). The main advantage of the proposed VEMO RA antenna is that it achieves high gain with a design that is straightforward, low-cost, and easily deployable while occupying only a small portion of the payload volume. These characteristics are ideal for many SmallSat applications, such as satellite communications, remote sensing, and deep space research.
