The Automated Identification System (AIS) was originally developed as a terrestrial system tracking vessels near the coastline. Dedicated channels were allocated within the spectrum historically reserved for maritime applications in the very high frequency (VHF) band, enabling long range communications, up to a few kilometers. There have been various initiatives in the last decade that extended this system with a space segment, enabling global monitoring of vessels beyond the range of terrestrial stations. Recently, the World Radiocommunication Conference has allocated frequencies for the extension of this system to a two-way VHF Data Exchange System (VDES) via satellite. This requires to adapt spaceborne antenna solutions previously developed for AIS, particularly for missions using small satellites and CubeSats. This paper provides a timely review of existing VHF antenna solutions and new concepts under development which could be applicable to VDES missions. Some key metrics are identified to provide a comparative study between various candidate solutions. Considering the range of possible missions, from secondary payloads on-board larger satellites to dedicated constellations, it is believed that a number of antenna products can find application in future VDES space-based infrastructure.

甚高频数据交换系统天线技术回顾

自动识别系统 (AIS) 最初是作为陆地系统跟踪海岸线附近的船只而开发的。在历史上为甚高频 (VHF) 频段的海事应用保留的频谱内分配了专用信道，可实现长达几公里的远程通信。在过去十年中，有各种举措将该系统扩展到空间部分，从而能够对地面站范围之外的船只进行全球监测。最近，世界无线电通信大会为通过卫星将该系统扩展到双向 VHF 数据交换系统 (VDES) 分配了频率。这需要采用以前为 AIS 开发的星载天线解决方案，特别是对于使用小型卫星和 CubeSat 的任务。本文及时回顾了现有的 VHF 天线解决方案和正在开发的可适用于 VDES 任务的新概念。确定了一些关键指标，以提供各种候选解决方案之间的比较研究。考虑到可能的任务范围，从大型卫星上的次要有效载荷到专用星座，相信许多天线产品可以在未来的 VDES 天基基础设施中找到应用。
