A small structure for chipless RFID tag is proposed; it is inspired by a C-shaped structure and based on HCSRR. This structure has curved strips, which are obtained by fine cutting the substrate from the symmetry of the C-shaped structure as base structure, and then missing part of the path is compensated by creating the PMC boundary condition in the cut-off point according to the image theory. Hence, the resonant frequencies of the proposed structure remain the same as those of the base structure. The substrate is Rog4003 with ϵ_r =3.55 and dimensions of 30×15×0.8 mm³, the ratio of area to lambda for the first resonant in 2.4 GHz is 0.073, and the average distance between two resonances is 300 MHz Half the structure without adding any other element reduces the production cost by 50%. Moreover, the structure can be printed on flexible substrates due to its simple design and non-complexity.

提出了一种用于无芯片RFID标签的小型结构。它的灵感来自C形结构，并基于HCSRR。该结构具有弯曲的条带，这些条带是通过从作为基础结构的C形结构的对称性中精细切割基板而获得的，然后通过根据切点在切点处创建PMC边界条件来补偿路径的缺失部分。图像理论。因此，所提出的结构的共振频率保持与基础结构的共振频率相同。衬底是用Rog4003 ε _{- [R} = 3.55和30×15×0.8 mm尺寸³，在2.4 GHz的第一次谐振中，面积与λ之比为0.073，两次谐振之间的平均距离为300 MHz，无需添加任何其他元素的一半结构将生产成本降低了50％。此外，由于其简单的设计和非复杂性，该结构可以印刷在柔性基板上。
