Abstract

A model for a cylindrical antenna consisting of a n-wire cage in a multilayer medium is presented for the computation of the current distribution along and around the antenna. A moment-method treatment based on the thin wire approximation and the mixed potential integral equation is employed for the new model. The vector potential is represented by a dot product of a dyadic kernel with the vector current density and the scalar potential by a double dot product of a dyadic kernel with the dyadic charge distribution. One of the antenna configurations presented in the paper is a horizontal antenna above a dielectric half-space
