摘要

提出了一种能够增加无源RFID系统工作范围的多读卡器系统。这种范围增益是通过使用阅读器射频波的建设性叠加获得的。设计了一个由两个读写器单元和一个中心单元组成的相干多读写器演示系统。演示系统在UHF频段运行，并允许其单元的任意分布放置。仿真结果和室内测量结果表明，与单读卡器相比，多读卡器系统的范围明显更大。

A coherent multi-reader approach to increase the working range of passive RFID systems

A multi-reader system is presented which is capable of increasing the working range of passive RFID systems. This gain in range is obtained by using constructive superposition of the readers' RF waves. A coherent multi-reader demonstrator system has been designed that consists of two reader units and one central unit. The demonstrator system operates in the UHF band and allows for an arbitrary distributed placement of its units. Simulation results and indoor measurements are presented, which show a significant larger range of the multi-reader system in comparison to a single-reader.
