2D MXenes in RF and Microwave Devices — Fact Fiction or Future?

Two-dimensional MXenes, particularly Ti3C2, are emerging as promising conductors for next-generation RF and microwave devices. Their unique combination of flexibility, tunable conductivity, and compatibility with additive manufacturing opens pathways for lightweight, conformal antennas and sensors. This workshop presentation examines the potential and limitations of MXenes in applications such as RFID antennas, 3D-printed antenna structures, and dip-coated flexible substrates. Key considerations include conductivity versus skin depth at microwave frequencies, the trade-offs between sheet resistance and mechanical compliance, and the manufacturability of scalable transmission lines. We will highlight whether these 2D materials represent a practical alternative to metals or remain a future promise.
