Summary:为了实现无芯片射频识别标签的低成本、小型化和大容量设计要求，提出了一种单面紧凑、可完全印制并基于导体自然谐振的无芯片射频识别（RFID）双极化标签的设计。利用谐振体的极化特性，在垂直极化和水平极化的两种平面波激励下，通过极化复用，该标签在固定的超宽带频段内容纳的数据位数提高了1倍，在22．48×22．48mm。的尺寸内可实现18位编码容量。通过仿真，得到标签的雷达散射截面（RCS）曲线，验证了标签结构的可行性。

In order to realize the low cost, miniaturization and large capacity design requirements of chipless RFID tag, this paper presents a design of chipless radio frequency identification（RFID） dual polarized label which is compact and can be printed com- pletely based on conductor natural resonance. Using the polarization characteristics of the resonator, the number of bits of data stored in the fixed UWB band is doubled by polarization multiplexing under two kinds of plane wave excitation of vertical polarization and horizontal polarization. The 18 bit encoding capacity can be achieved within 22.69×22.69 mm^2 size. Through the simulation, the radar cross section（RCS） curve of the tag is obtained, and the feasibility of the tag structure is verified.
