为解决贴片天线带宽窄的问题,文章提出了基于超材料和环谐振器耦合模型的解决方案。该模型不仅具有超材料宽频特性,并且通过引入环谐振器,进一步提高了超材料天线的带宽。此外,利用耦合模型的对称特性,研究了该模型在双极化天线中的应用。结果表明,该模型可以应用到现阶段的5G通信系统,完全覆盖5G的N77频段(3.3~4.2 GHz)。

In order to solve the problem of narrow bandwidth of patch antenna,a solution based on the coupling model of metamaterial and ring resonator is proposed.This model not only has the broadband characteristics of metamaterials,but also further improves the bandwidth of metamaterial antennas by introducing ring resonators.In addition,the application of this model in dual-polarized antennas is studied by using the symmetry characteristics of the coupling model.The results show that the model can be applied to the 5G communication system at the present stage and completely cover the N77 frequency band of 5G(3.3~4.2 GHz).
