| 摘 要： | 提出了一种非均匀排列超材料结构.通过理论计算,该结构在Ku频段内的等效相对介电常数可以控制在0到1之间.该结构可用于天线罩提高天线的增益.分别对单个微带天线、2×2微带阵列天线、4×4微带阵列天线3种情况加载超材料天线罩的效果进行仿真.仿真结果表明:超材料天线罩对提高天线及天线阵增益的效果随着天线单元数的增加而减弱,如单个微带天线增益可提高6dB,而4×4微带阵列天线增益的提高只有1.6dB.

| Abstract: | A kind of metamaterial with inhomogenous structure was designed.Its equivalent relative permittivity in Ku band can be controlled between 0and 1by theoretical calculation.This structure is used as a radome to improve the antenna gain.We put the metamaterial radome on the single microstrip antenna,2×2microstrip array antenna,4×4microstrip array antenna respectively and simulate them in HFSS.The simulation results show that the improvement on the single microstrip antenna and array antenna weaken as the increase of antenna unit,such as the enhancement of gain on the single microstrip antenna is 6dB,while the 4×4microstrip array antenna is only 1.5dB. |
