空天地一体化网络（SAGIN）集成了具有不同覆盖范围、移动性和载荷约束的异构平台，这对灵活的天线架构产生了强烈需求。可折叠天线阵列（FAAs）通过可控关节或铰链重构阵列几何形状、天线位置和方向，提供了一种有前景的解决方案。然而，现有关于FAAs的研究主要考虑了简单的折叠配置和有限的部署效益，而FAAs的架构及其在SAGIN中的更广泛潜力在很大程度上仍未得到探索。在本文中，我们介绍了FAA的基本原理和架构，包括折叠机制、可折叠性级别和功能能力。然后，我们考察了FAA在地面基站、低空平台、高空平台和卫星上的应用，以及它们潜在的挑战和解决方案。最后，我们强调了开放问题和未来研究方向，并提供了一个案例研究，以展示FAA在SAGIN中实现的通信性能提升。
英文摘要
Space-air-ground integrated networks (SAGINs) integrate heterogeneous platforms with different coverage, mobility, and payload constraints, which creates strong demands for flexible antenna architectures. Foldable antenna arrays (FAAs) provide a promising solution by reconfiguring array geometry, antenna positions, and orientations through controllable joints or hinges. However, existing studies on FAAs have mainly considered simple folding configurations and limited deployment benefits, while FAAs' architectures and broader potential for SAGIN remain largely unexplored. In this article, we present the fundamentals and architectures of FAA, including folding mechanisms, foldability levels, and functional capabilities. We then examine FAA applications for ground base stations, low-altitude platforms, high-altitude platforms, and satellites, together with their potential challenges and solutions. Finally, we highlight open issues and future research directions, and provide a case study to demonstrate the FAA-enabled communication performance improvement in SAGIN.
