摘要

本文介绍了毫米波射频识别(MMID)系统通信信道测量活动的分析和结果。选择测量设置是为了满足mid应用程序场景的需求。利用矢量网络分析仪和定制的yagi-uda天线，在55 - 65 GHz的频率范围内测量了该信道。利用功率延迟曲线对测量数据在频域和延迟域进行分析。功率延迟曲线显示了多径传播和延迟色散的影响。通道传递函数随距离增加的变化可以用自由空间损失模型来近似。

Measurements and analysis of MM-Wave RFID channels

In this paper, the analysis and the results of a measurement campaign for the communication channel of a mm-wave radio frequency identification (MMID) system are presented. The measurement setup was chosen to meet the requirements of a MMID application scenario. Using a vector network analyzer and custom made yagi-uda antennas, the channel was measured in the frequency range of 55 - 65 GHz. The measurement data was analyzed in the frequency domain and in the delay domain using the power delay profile. The power delay profile shows an influence of multipath propagation and delay dispersion. The variation of the channel transfer function over increasing distances can be approximated by the free space loss model.
