Since its inception, multiple-input multiple-output (MIMO) has become a magical technology that continues to break new grounds and deliver the needed upgrades in mobile communications. The emerging 5G systems are also being labelled by many as the massive MIMO generation. This somewhat oversimplified view is perhaps a reflection of the great impact MIMO has had on our generation of mobile communication networks. Although the technologies have evolved in the past decades, the principle remains the same—to exploit the diversity of different copies of signals at independent locations for reducing the degree of fading and randomness of wireless channels. Through signal processing and coding, the diversity has been translated successfully into capacity gain and enhancement in other forms of the quality-of-service. This article identifies “fluid” antenna as a trending technology that may succeed MIMO and become a reality to transform wireless communications to a new height. Fluid antenna is a radical approach that advocates software-controlled position-flexible shape-flexible antenna. The concept liberates antennas to unleash massive diversity inherent in the small space of a mobile device and makes possible new opportunities that were previously unthinkable. This article attempts to be imaginative and aims to take readers on a short journey of what fluid antenna might bring in future-generation mobile communications systems and speculate on its impact.

用于 6G 的流体天线系统：当李小龙启发无线通信时

自问世以来，多输入多输出 (MIMO) 已成为一项神奇的技术，它不断开拓新领域并提供移动通信所需的升级。新兴的 5G 系统也被许多人称为大规模 MIMO 一代。这种有些过于简单化的观点可能反映了 MIMO 对我们这一代移动通信网络产生的巨大影响。尽管这些技术在过去几十年中有所发展，但原理仍然相同——利用独立位置不同信号副本的多样性来降低无线信道的衰落程度和随机性。通过信号处理和编码，多样性已成功转化为其他形式的服务质量的容量增益和增强。本文将“流体”天线确定为一种趋势技术，可能会接替MIMO，成为将无线通信提升到新高度的现实。流体天线是一种激进的方法，提倡软件控制的位置灵活的形状灵活的天线。这一概念解放了天线，以释放移动设备狭小空间内固有的大量多样性，并使以前无法想象的新机会成为可能。本文试图富有想象力，旨在让读者短途旅行，了解流体天线可能为下一代移动通信系统带来什么，并推测其影响。流体天线是一种激进的方法，提倡软件控制的位置灵活的形状灵活的天线。这一概念解放了天线，以释放移动设备狭小空间内固有的大量多样性，并使以前无法想象的新机会成为可能。本文试图富有想象力，旨在让读者短途旅行，了解流体天线可能为下一代移动通信系统带来什么，并推测其影响。流体天线是一种激进的方法，提倡软件控制的位置灵活的形状灵活的天线。这一概念解放了天线，以释放移动设备狭小空间内固有的大量多样性，并使以前无法想象的新机会成为可能。本文试图富有想象力，旨在让读者短途旅行，了解流体天线可能为下一代移动通信系统带来什么，并推测其影响。
