Abstract
The analytical expressions for the fields at the earth surface due to a satellite-borne horizontal dipole are derived for an idealized model in which the Earth's magnetic field is vertical and the medium is divided into plane, parallel slabs. Although nonlinear phenomena in the neighborhood of the antenna are not analyzed, the problem is circumvented by defining an equivalent infinitesimal dipole whose external fields are the same as those of the actual antenna. Finally, a numerical example is given in which the fields of such a horizontal dipole are compared with those of a vertical dipole operating in the same conditions.
