摘　　要：We present the design and analysis of a novel modified H-shaped split ring resonator （SRR） metamaterial. It has negative permeability and permittivity characteristics with multi-band resonance for the X, Ku, and Ka frequency bands. Different configurations of the patch antenna have been analyzed with different orientations and positions of the metamaterial. Optimized performance was achieved with the new shape of the metamaterial antenna with an appreciable 9 dB gain, 77 GHz bandwidth, 100% radiation efficiency, and 65% reduction in active area. The second-order fractal metamaterial antenna achieves high miniaturization on the order of 1/21. This is truly a boon in the communications world, as a sharp beam with smaller physical di- mensions is urgently required.本文设计并分析了一种改进H形裂环谐振器(split ring resonator,SRR)的新型超材料。它具有负磁导率和负介电常数特性,且在X,Ku和Ka频带内具有多频共振特性。本文就超材料方向和位置的变化对不同配置下的贴片天线进行了分析。结果表明,新型超材料天线实现了性能优化,表现为9 d B的可观增益,77 GHz的带宽,100%的辐射效率,以及有源区65%的面积缩减。二阶分形超材料天线尺寸降至1/21,从而实现了高度小型化。该研究为急需小尺寸尖波束的通信领域提供了一种解决方案。
