无人机（UAV）正在被考虑用于要求高带宽、低延迟通信的场景，以进行视频和传感器数据传输以及实时控制。UAV还可以用作移动的空中基站（BS），用于在紧急情况下维持通信。毫米波（mmWave）频带（包括100 GHz以上的亚太赫兹频率）是用于高数据速率UAV连接的有吸引力的技术，这是由于在这些频率下可用的宽带宽。本文研究了天线和码本设计的无人机通信在28和140 GHz的现实天线模拟和飞行模式。分析表明，多阵列配置与适当的码本设计是必要的均匀的球形覆盖，并成为在远程应用中尤为重要。因此，本文提出了一个四阵列设计与贴片天线。仿真表明，该设计可以在1公里范围内实现超过1 Gbps的数据速率，具有合理的功率水平和适度的雨衰。一个真实的公共安全使命飞行的模拟表明，即使在无人机高度移动和旋转的情况下，也可以保持光束跟踪。
Unmanned Aerial Vehicles (UAVs) are steadily being considered for scenarios demanding high bandwidth, low latency communications for video and sensor data transfer as well as real-time control. UAVs may also be used as mobile aerial Base Station (BS) for maintaining the communication in emergency scenarios. The millimeter wave (mmWave) bands, including the sub-THz frequencies above 100 GHz, are an attractive technology for high data rate UAV connectivity due to the wide bandwidths available at these frequencies. This paper studies antenna and codebook design for UAV communication at both 28 and 140 GHz with realistic antenna simulations and flight patterns. The analysis shows that multi-array configurations with proper codebook design are necessary for uniform spherical coverage and become particularly important in long range applications. The paper thus proposes a four array design with patch antennas. Simulations indicate that the design can achieve in excess of 1 Gbps data rates at a range of 1 km, with reasonable power levels and moderate rain fades. A simulation with a real public safety mission flight shows that beam tracking can be maintained even under high drone movements and rotations.
