用于立方体卫星的高增益天线技术与发展趋势

随着MarCO与RainCube的成功在轨验证，立方体卫星已经在深空探测与遥感领域展现出独特的优势。立方体卫星搭载的天线不仅需要提供良好的辐射特性，还必须满足立方体卫星苛刻的体积和重量限制，这种限制条件在设计大口径高增益天线时尤为重要。首先简要介绍了立方体卫星的起源、发展及其应用前景，其次重点介绍了立方体卫星高增益天线的技术特点、研究现状及其在轨验证情况，最后归纳总结了立方体卫星高增益天线技术的未来发展趋势，为我国后续开展立方体卫星研究与应用提供参考。

Development trends of high-gain antennas technology for CubeSats

With the successful on-orbit demonstrations of MarCO and RainCube, CubeSats have demonstrated their outstanding advantages in the areas of deep space communication and remote sensing research. Antennas fitted in CubeSats are required not only to provide excellent radiation performance but also to meet the critical limits on volume and weight, which are especially important for high-gain antennas with large apertures. The origin and advantages of CubeSats technologies are introduced, and then the current status and on-orbit demonstrations of high-gain antennas for CubeSats are presented. Finally, the development trends of high-gain antennas technology for CubeSats are summarized, which provides a reference for the further study and application of CubeSats in China.
