Breakthrough in Surface Printing Technology! Dalian University of Technology drone skin antenna achieves stable communication at 50 kilometers

        Recently, the unmanned aerial vehicle (UAV) skin ultra-thin integrated RF sensor developed by the research team of Dalian University of Technology was successfully launched at the Pucheng Flight Test Center in Shaanxi Province, marking the practical application of China's curved antenna full 3D printing technology. The antenna serves as the "perception center" of the drone, using a poly (arylene ether) light cured resin substrate containing multiple fluorine structures. Through independent innovative curved surface manufacturing methods, it seamlessly integrates with the drone skin, solving the pain points of large volume and poor surface adaptation of traditional planar antennas. Tests have shown that its signal transmission efficiency exceeds 95%, with a gain doubled compared to traditional products. It can stably receive signals within a 50 kilometer line of sight and can be adapted to various fields such as ships and ultra high speed aircraft. The relevant achievements have been published in the Journal of Chemical Engineering and have been tested and verified by China Electronics Technology Group Corporation and China Shipbuilding Industry Corporation.
