Abstract

The problem of radiation of the coupled horizontal wire antennas with a specified current distribution, located near to a planar interface between two media is considered. Expressions for evaluation of a mutual impedance, mutual radiation resistance and mutual resistance of losses between dipoles above the ground are obtained. The results of numerical evaluations of the mutual resistances between two half-wave dipoles as functions against a distance between them are presented in graphical form.
