| Abstract Scope |
Additive manufacturing has revolutionized the realm of RF electronics, enabling the rapid prototyping and fabrication of electromagnetic structures using nontraditional materials. These materials, while allowing for significant flexibility in system form factors, present numerous design challenges such as substrate curvature, high surface roughness, and connection reliability. For example, the placement of discrete packages using conductive inks may result in wicking, causing unintentional shorting and poor component adhesion. This work demonstrates solutions to many of these issues, including the use of anisotropically conductive inks, printed press-fit PCB interconnects, RF-transparent protective coatings, and printed interposers for various package sizes. As a case study, we utilize these techniques to fabricate an RF detection system within a doubly-curved E-glass laminate, including printed antennas, vias, and transmission lines. Our work can offer unique and innovative ideas towards how additively manufactured RF circuits may be applied to meet novel design goals within existing systems. |
