摘要

提出了一种基于平面超材料结构的新型超宽带微带贴片天线。该超材料微带天线具有两层，包括网状的顶部贴片和图案化的接平面。由于地平面和图案辐射贴片耦合的电感和电容导致了超材料的左旋行为。该天线设计在低成本的FR4基板上，尺寸为28×32 mm2，高度为0.794mm。阻抗带宽在3.3 ~ 12ghz范围内工作，s参数小于- 10db。仿真研究结果表明，该天线具有良好的超宽带辐射特性。

A novel compact ultra-wideband metamaterial-based microstrip antenna

A novel compact Ultra-wideband (UWB) microstrip patch antenna using planar metamaterial structures is proposed. The metamaterial microstrip antenna has two layers consists of a meshed top patch and a patterned ground plane. The inductances and capacitances coupled due to the ground plane and patterned radiating patch leads to the left handed behavior of the metamaterial. The proposed antenna which designed on the low cost FR4 substrate has compact size 28×32 mm2 with height 0.794mm. The impedance bandwidth operates from 3.3 to 12 GHz for S-parameter of less than -10 dB level. The results obtained from the simulation studies shows that the antenna has good radiation characteristics for the UWB applications.
