增强标签反向散射能量的装置及方法
Abstract:
射频识别标签的输入电能被监控。基于所述监控到的输入电能，所述标签的输入阻抗被调节，以增强所标签反向散射能量。本发明的一个实施例中，监控整流装置的输出电压。基于所述监控到的输出电压，确定所述标签的输入电能。基于所述输入电能，调节所述标签的输入阻抗，以增强所标签反向散射能量。
Abstract(English):

An input power on a tag is monitored. An input impedance of the tag is adjusted based on the monitored input power to increase a backscatter level of the tag. In one embodiment, an output voltage of a rectifier device is monitored. An input power to the tag is determined based on the output voltage. An input impedance of the tag is adjusted based on the input power to increase the backscatter level of the tag.
