In this study, a 2-D mathematical model of a high-directive microwave antenna with a miniaturized volume profile is developed analytically. The antenna is a rectangular patch antenna on a metaferrite substrate. The substrate is a parallelepiped-shaped dielectric matrix with periodically embedded thin cylindrical ferromagnetic inclusions of a circular cross section. It is assumed that the inclusions are fully or partially magnetized by an external DC bias magnetic field. It has been shown that the use of such a metamaterial substrate, instead of a dielectric one with the same values of permittivity and permeability, leads to a miniaturization of the volume profile of the antenna and an increase in its efficiency and power gain. The commercial electromagnetic software is used in the study to validate the proposed antenna model.

在这项研究中，分析开发了具有小型化体积剖面的高指向性微波天线的二维数学模型。天线是在超铁氧体基板上的矩形贴片天线。基板是平行六面体形状的介电矩阵，具有周期性嵌入的圆形横截面的薄圆柱形铁磁夹杂物。假设夹杂物被外部直流偏置磁场完全或部分磁化。已经表明，使用这种超材料基板，而不是具有相同介电常数和磁导率值的电介质基板，会导致天线体积分布的小型化，并提高其效率和功率增益。研究中使用商业电磁软件来验证所提出的天线模型。
