摘要

本文研究了超水汽对60GHz微带天线辐射方向图的影响。采用砷酸镓辩证衬底,设计了一种新型的基于超材料天线的方形劈裂环谐振器和传统微带贴片天线,研究了天线比例图的影响。超材料天线是利用印刷在砷化镓电介质上的方形分裂环谐振器阵列设计的单层超材料反射面制成的。通过调整反射面高度来提高辐射方向图性能。结果表明,在不影响天线谐振频率的情况下,具有超材料反射面的天线辐射方向图的增益比没有超材料覆盖层的传统贴片天线提高了1.2dB。利用高频结构模拟器(HFSS)对超材料衬底和天线结构进行了仿真分析。

Modeling and Simulation Metamaterail Effects on Radiation Pattern Of Micro strip Antenna
This paper presents effect of metamater ail on the radiation pattern of microstrip antenna at 60GHz band. A new design of metamaterial antenna based Square Split Ring Resonator and a conventional microstrip patch antenna both designed using gallium arsenate dialectical substrate to study the effect of ration pattern of antenna. The metamaterial antenna is made by using a single layer of metamaterial reflecting surface which is design from array of squared split ring resonator (SRR) printed on a GaAs dielectric. The height of reflecting surface is adjusted to improve the radiation pattern performance. The results show that the gain of the antenna radiation pattern with metamaterial reflecting surface is increased by 1.2dB compared with conventional patch antenna without the metamaterial superstrate without distorting the antenna resonance frequency. High Frequency Structure Simulator (HFSS) was used to simulate and analysis the metamaterial substrate and antenna configurations.
