摘要

针对读写器高功率载波信号干扰弱标签信号的问题，提出了一种基于多端口反射计端口响应测量频率下变频的全自动网络分析仪。这种方法不需要载波信号读取器补偿。得到了新仪表的基本测量方程。讨论了所提出的电表的优点。讨论了基于多通道矢量电压表的射频识别读写器的测量和标定算法。在只考虑多探头传输线反射计响应的情况下，标定算法建立在对入射波和反射波复幅的初始估计基础上。给出了该方法的基本方程。给出了测量和校准过程的计算机模拟结果，证实了理论结论。

A RFID reader based on combined multi-port reflectometer

A use automatic network analyzer based on down conversion of measuring frequency of multi-port reflectometer ports' responses is proposed to overcome the problem of weak tag signal blocking by a high-power carrier signal from reader. This approach does not require the carrier signal reader compensation. The basic measuring equations of the new meter are obtained. The advantages of the proposed meter are discussed. Measurement and calibration algorithms of radio frequency identification reader based on a multi-channel vector voltmeter are discussed in the paper. The calibration algorithm is founded on initial estimation of incident and reflected wave complex amplitudes when only the responses of multi-probe transmission line reflectometer are considered. The basic equations of the method are given. The results of computer simulation of measuring and calibration processes confirming the theoretical conclusions are given.
