摘要
电磁超材料是指一种具有与常规材料不同的电磁特性的人工电磁媒质,近零折射率电磁超材料是电磁超材料的一种,以其等效折射率接近为零作为主要特征,在覆层天线方面有广泛的应用.主要研究近零折射率材料作为天线覆层时,不同的覆层与天线距离对天线的影响,为实际应用提供一定的参考.
Abstract
Metamaterials are a kind of artificial electromagnetic medium with different novel properties from conventional materials.As a kind of metamaterial,near-zero refractive index media has been widely used in super-strate antennas because its equivalent refractive index is close to zero.The effect of different distance between the superstrate and antennas when the near-zero refractive index metamaterials are used as antenna superstrates is studied,which can provide some reference for the practical application.
