On the radiation from a vertical dipole with an inductive wire-grid ground system

The far field of a vertical electric dipole on a sectionally homogeneous ground plane is considered. The specific model used is a dielectric-like ground which is modified by using an inductive wire grid or mesh screen in a region surrounding the dipole. Attention is focused on the modification of the radiation pattern resulting from the presence of the inductive ground screen. It is demonstrated that the low-angle radiation may be greatly enhanced by a ground screen which extends out to 15 or more wavelengths.
