摘要

本文认为，采用方向图可重构天线器件是利用环境(或杂散)无线通信WiFi信号进行人体尺度无源无线电传感的新机遇。方向图可重构天线允许将天线辐射方向图动态地引导到预定的感兴趣方向。这些天线是即将推出的5G设备和下一代WiFi无线电中必不可少的射频组件。讨论了被动运动检测的信号建模、波束导向技术集成和自适应。还考虑了智能工作空间中的第一个案例研究和性能分析。

Pattern reconfigurable antennas for passive motion detection: WiFi test-bed and first studies

The paper considers the adoption of pattern reconfigurable antenna devices as a new opportunity for human-scale passive radio sensing using ambient (or stray) WiFi signals designed for wireless communications. Pattern reconfigurable antennas allow to dynamically channelize the antenna radiation pattern to pre-defined directions of interest. These antennas are essential RF components both in forthcoming 5G devices and next generation WiFi radios. We discuss signal modeling, beam-steering technology integration and adaptation for passive motion detection. First case studies and performance analysis inside a smart workspace are also considered.
