INFLUENCE OF A SECTOR GROUND SCREEN ON THE FIELD OF A VERTICAL ANTENNA

Abstract

The field of a short vertical antenna on a homogeneous ground is shown to be modified by the presence of a metallic screen. The screen is taken in the form of a circular disc and a concentric sector. The modification of the field is expressed in the form of surface integrals over the disc and the sector. Extensive numerical results for these basic integrals are given and a number of applications are illustrated.
