Laser enhanced direct print additive manufacturing (LE-DPAM) technology has recently been demonstrated to achieve success in packaging of antennas with phase shifters to realize passive phased antenna arrays (PAAs). Utilizing LE-DPAM for PAAs operating in mm-wave bands brings out new challenges that need to be addressed. These challenges are associated with smaller antenna and feature sizes needed for mm-wave band operation, necessity of active circuits for amplification, and number of pads, pad size and pad locations of mm-wave beamformer IC packages. This paper presents our initial progress in scaling LE-DPAM based packaging of PAAs into the mm-wave band operation through consideration and demonstration of discrete components (i.e. antenna array elements and beamformer ICs) that form the PAA structure. Specifically, a stand-alone, passive, 2×2 LE-DPAM based 26 GHz antenna subarray is investigated for its performance. In addition, a 24.5 GHz – 27 GHz beamformer IC is packaged in a stand-alone test article using LE-DPAM and investigated for its mm-wave performance and thermal aspects.

Laser enhanced direct print additive manufacturing for mm-wave components and packaging
Direct print additive manufacturing (DPAM) is an additive manufacturing technique that combines fused deposition modeling with micro-dispensing. As a multimaterial 3D printing method it has proven to be effective for fabricating printed electronics that operate in the microwave frequency range. This paper discusses the addition of picosecond laser processing to the DPAM process, and the enhancements to high-frequency performance and design capability that are made possible. The use of laser-enhanced DPAM for 3D fabrication of transmission lines, passive components and packaging is discussed.

Radio frequency (RF) fingerprinting is a hardware-based authentication technique utilizing the distinct distortions in the received signal due to the unique hardware differences in the transmitting device. Existing RF fingerprinting methods only utilize the naturally occurring hardware imperfections during fabrication; hence their authentication accuracy is limited in practical settings even when state-ofthe-art deep learning classifiers are used. In this work, we propose a Chaotic Antenna Array (CAA) system for significantly enhanced RF fingerprints and a deep learning-based device authentication method for CAA. We provide a mathematical model for CAA, explain how it can be cost-effectively manufactured by utilizing mask-free laser-enhanced direct print additive manufacturing (LE-DPAM), and comprehensively analyze the authentication performance of several deep learning classifiers for CAA. Our results show that the enhanced RF signatures of CAA enable highly accurate authentication of hundreds of devices under practical settings.more » « less

Additive manufacturing (AM) is increasingly being shown as a viable technology for the fabrication of complex 3D structures. For microwave components, the combination of laser processing and AM techniques has been reported to enhance the performance and frequency limits of the devices. In this paper, a process to fabricate a 200 μm × 200 μm × 200 μm vertical interconnect that combines fused deposition modeling (FDM), micro-dispensing, and picosecond laser machining is studied. A test structure that includes two vertical transitions is designed, fabricated, and tested, as a performance benchmark. The 4 mm long structure shows a low dissipative loss (2.5 dB at 45 GHz) and excellent frequency response up to mm-wave frequencies. The described structure will help to enable the fabrication of high-performance structural RF electronics.more » « less

Abstract The advancement of additive manufacturing has significantly transformed the production process of metal components. However, the unique challenges associated with layer-by-layer manufacturing result in anisotropy in the microstructure and uneven mechanical properties of additive-manufactured metal products. Traditional testing methods often fall short of providing the precise mechanical performance evaluations required to meet industry standards. This paper introduces an innovative approach that combines a nondestructive Lamb wave sensing system with a wavenumber analysis method to characterize the mechanical properties of 3D-printed metal panels in multiple directions. Our method employs piezoelectric actuators (PZT) to generate Lamb waves and utilizes a laser Doppler vibrometer (LDV) for non-contact, two-dimensional grid acquisition of the wavefield. The anisotropic properties of the metal 3D-printed structure will be captured in the wavefield, offering an informative dataset for wavenumber analysis. The proposed analytical method includes multi-directional frequency wavenumber analysis and a least-squares-based dispersion curves regression. The integration of the above advanced analytical tools allows for the accurate characterization of the shear wave velocity and Poisson’s ratio of the plate structure. This precise characterization is crucial for ensuring the structural integrity and consistent mechanical properties of 3D-printed metal components. We validated our method using a 3D-printed stainless-steel plate, demonstrating its capability to effectively characterize the multi-directional mechanical properties of additively manufactured metal plates. We expect that our method can provide a nondestructive, time-efficient, and comprehensive quality control solution for additive manufacturing across various industries.more » « less
