The Radiation Characteristics of VLF Horizontal Wire Antennas over Multi-layered Earth
Abstract— In this paper, the influence of the earth resistivity characteristics on the radiant field excited by a very low frequency(VLF) horizontal wire antenna is studied, and a 1D isotropic model of the horizontal layered earth is established. Theoretical formulas for the apparent resistivities of the layered ground and the electromagnetic field of antennas are derived for the case of observation points being on both of the site of antennas and far areas. The effects of different earth resistivity and multilayered earth on the radiation performances of the VLF horizontal antenna are simulated and analyzed. From the derivations and analyses, it is pointed out that the VLF horizontal antennas built on a region of high resistivity is conducive to radiant electromagnetic field effectively.
