Analytical model for miniaturized patch antenna on metaferrite-like substrate

Abstract

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.
