无人机 (UAV) 辅助无线通信有望提供高速且经济高效的无线连接，而无需固定基础设施覆盖。它们是第六代（6G）无线网络的关键技术推动者，其中将部署包括太空、航空和地面网络在内的三维覆盖，以保证无缝服务的连续性和可靠性。由于空气动力学的要求，非常需要采用能够跟随无人机形状的共形天线，以减少额外的阻力和燃料消耗。为了实现 6G 网络的百吉比特每秒 (Gb/s) 数据速率和大规模连接，毫米波和更高频率范围的通信需要具有高增益和波束扫描/多波束功能的共形天线阵列。然而，在无人机平台设计和实现高增益共形阵列方面存在新的挑战。在本文中，我们概述了基于无人机的无线通信的共形发射阵列的最新进展，介绍了新的设计方法并强调了可利用的新机会。
Unmanned aerial vehicles (UAVs) aided wireless communications promise to provide high-speed cost-effective wireless connectivity without needing fixed infrastructure coverage. They are a key technology enabler for sixth generation (6G) wireless networks, where a three-dimensional coverage including space, aero and terrestrial networks are to be deployed to guarantee seamless service continuity and reliability. Owing to the aerodynamic requirements, it is highly desirable to employ conformal antennas that can follow the shapes of the UAVs to reduce the extra drag and fuel consumption. To enable hundred giga-bits-per-second (Gb/s) data rates and massive connectivity for 6G networks, conformal antenna arrays featured with high gains and beam scanning/multiple beams are demanded for millimeter-wave and higher-frequency-range communications. However, new challenges exist in designing and implementing high-gain conformal arrays for UAV platforms. In this article, we overview the recent advances in conformal transmitarrays for UAV-based wireless communications, introducing new design methodologies and high-lighting new opportunities to be exploited.
