The estimate of Hertz dipole patterns using finite difference time domain (FDTD) simulation for case a layered-inhomogeneous underlying surface

Abstract

Abstract The directional characteristics of horizontal Hertz dipole obtained at the result of the modeling process are presented. The elementary emitter was situated near the vertically layered dielectric surface. The vertical heterogeneity corresponded to frozen soil covered with a layer of snow. The modeling considered two types of soils: sandy and loamy clay. We used the finite difference time domain method for modeling. It was found that snow and soil’s properties affect the directional characteristics of the dipole. These results can be used to assess the influence of the underlying surface on the directional characteristics of antennas located on the territory with season snowfall.
