摘　　要：提出一种新型的频域无芯片编码方法,将用于编码的多谐振器在空间排列上进行了水平偏移。在频率2.65~3.75 GHz范围内,长度为50 mm、宽度为30 mm的RT/duroid 5880基板上设计并实现了12位的无芯片编码,仿真和测试结果都表明该方法能够有效减小无芯片RFID标签各谐振器之间的电磁耦合,提高雷达散射截面(RCS)响应,从而显著提高无芯片RFID标签识别的可靠性。In this paper, a novel chip-less coding method in frequency domain is proposed, and the multi-resonator used for coding is offset horizontally in the spatial arrangement. In the frequency range of 2.65-3.75 GHz, 12 bit chip-less tag is designed and implemented in the RT/duroid 5880 substrate with the length of 50 mm and width of 30 mm. Simulation and test results show that the method can effectively reduce the electromagnetic coupling between the chip-less RFID tag resonator and improve the radar cross section(RCS) response, thus greatly improving the reliability of the chip-less RFID tag recognition.
