Abstract
The transient behaviour of the resistively loaded wire antenna radiating in the presence of a lossy half-space is analyzed in the time domain. The mathematical model is based on a corresponding time domain Hallen integral equation. The influence of a lossy half-space is taken into account via the Fresnel space-time reflection coefficient appearing in the integral equation kernel. The resulting integral equation is then solved by the space-time finite element procedure. Numerical results for the current distribution along the wire are obtained for the case of dielectric half-space.
