EMI Shielding Materials in Drones
Year: 2024
Type: article
Abstract: The rapid advancement of UAV technology has increased system complexity, particularly in cellular network applications where UAVs work alongside ground-based base stations. A major challenge is electromagnetic interference (EMI) in the radiofrequency (RF) band, caused by components such as motors and power supplies, which can disrupt communication signals. Effective shielding is crucial to ensure uninterrupted UAV operation, as external EMI from base stations can jeopardize UAV electronics, leading to unintended flight paths or loss of communication. This review explores enhanced security measures for UAV electronics in RF environments, proposing three materials for EMI shielding: reduced graphene oxide (RGO), electrically conductive epoxy resins filled with polyaniline (PANI) and polypyrrole (PPy), and hybrid polymer composites using a polyvinylidene fluoride (PVDF) matrix with few-layer graphene (FLG) and nickel spinel ferrites (NSF).
