摘要

提出了一种紧凑的宽带负折射率在线传输(NRI-TL)超材料天线，该天线由传统印刷单极子组成，以左旋方式加载。超材料负载允许天线被建模为5.5 GHz左右的短折叠单极子，同时作为3.55 GHz左右的地平面的平衡器，因此使地平面能够在该频率上辐射。因此，由于这两种辐射模式之间的正交性，超材料负载单极子天线具有非常宽的阻抗带宽。NRITL超材料单极天线在模拟-10 dB回波损耗带宽为3.84 GHz的同时，保持了高达90%的高效率，在3.3 ~ 3.8 GHz WiMax和5.15 ~ 5.85 GHz WiFi频段均实现了正交方向图分集。

A compact and broadband NRI-TL metamaterial monopole antenna

A compact and broadband negative-refractive-index transmission-line (NRI-TL) metamaterial antenna is proposed, which consists of a conventional printed monopole loaded in a left-handed fashion. The metamaterial loading allows the antenna to be modeled as a short folded monopole around 5.5 GHz, and simultaneously acts as a a balun for the ground plane around 3.55 GHz, therefore enabling the ground plane to radiate at this frequency. Consequently, the metamaterial-loaded monopole antenna exhibits a very wide impedance bandwidth by virtue of the orthogonality between these two radiating modes. The NRITL metamaterial monopole antenna has a simulated -10 dB return-loss bandwidth of 3.84 GHz while maintaining a very high efficiency in the order of 90%, and achieves orthogonal pattern diversity in both the 3.3 - 3.8 GHz WiMax and 5.15 - 5.85 GHz WiFi bands.
