传统的射频标签因含有芯片而导致价格高、功率需求大，使得射频标签无法广泛使用。基于导体结构的自然谐振特性，本文提出了一种新型无芯射频标签，该标签除了散射体本身不包含任何芯片和电路，可以大幅降低标签成本。仿真结果表明该标签谐振特性明显，通过改变标签的物理参数使不同标签在不同频率点产生谐振，这样可以用来实现编码。利用矩阵束算法提取出的极点可以识别出该标签结构，表明该标签结构具有可行性。

Due to its high price and power demand, traditional chipped RFID tags couldn't be widely used. And thus a new chipless RFID tag based on natural resonant characteristics of conductors is proposed. This tag contains no chip and circuit but contains only a scattering body, and as a result, the cost of tag is sub-stantially reduced. Simulation results indicate that the resonance characteristics of this tag are evident,and tags with different physical parameters resonate at different frequencies, and these features can be used to realize data encoding. Poles extracted by the matrix pencil method can indentify the tag structure, this in-dicates the feasibility of this tag structure.
