Various new conductive materials with exceptional properties are utilized for the preparation of electronic devices.Achieving ultra-high conductivity is crucial to attain excellent electrical performance.However,there is a lack of systematic research on the impact of conductor material thickness on device performance.Here,we investigate the effect of conductor thickness on power transmission and radiation in radio-frequency(RF)and microwave electronics based on MXene nanosheets material transmission lines and antennas.The MXene transmission line with thickness above the skin depth exhibits a good transmission coefficient of approximately-3 dB,and the realized gain of MXene antennas exceeds 2 dBi.Additionally,the signal transmission strength of MXene antenna with thickness above the skin depth is higher than 5-μm MXene antenna approximately 5.5 dB.Transmission lines and antennas made from MXene materials with thickness above the skin depth exhibit stable and reliable performance,which has significant implications for obtaining high-performance RF and microwave electronics based on new conductive materials. 展开更多
