Graphene-Assembled Film-Based Reconfigurable Filtering Antenna with Enhanced Corrosion-Resistance

Corrosion-resistance is the key to improve reliability and service lifespan of highly integrated reconfigurable filtering antennae. However, conventional methodology for corrosion prevention cannot achieve desired effects, due limited intrinsic corrosion-resistance capacity traditional metal-based devices. Here, we developed a antenna based on graphene assembled film (GAF), featuring significant enhancement. The GAF-based exhibits comparable electrical performance when compared with copper-based antenna, can flexibly switch between two working modes, including ultra-wideband (UWB, 2.8–11 GHz) narrowband (NBF, 3.23–3.77 GHz). To further demonstrate GAF, salt spray test found that steady properties after over 336 h, while shows rapid degradation. simulated experimental results are in agreement, indicating proposed GAF be applied broader application prospects communication systems, especially severe environments.
