Only conventional metals meet the requirements for emerging RF devices so far. A team of researchers in the US (Drexel University, Villanova University, industry) has developed Ti3C2Tx MXene microstrip transmission lines with low‐energy attenuation and patch antennas with high‐power radiation at frequencies from 5.6 to 16.4 GHz. The antenna was manufactured by spray‐coating from aqueous solution. They demonstrated that an MXene patch antenna array with integrated feeding circuits on a conformal surface has comparable performance with that of a copper antenna array at 28 GHz, which is a target frequency in practical 5G applications. The versatility of MXene antennas in wide frequency ranges coupled with the flexibility, scalability, and ease of solution processing makes MXene promising for integrated RF components in various flexible electronic devices…read more.
