In computational electromagnetics, ‘one size does not fit all.’ The transition between a ground acting as a good dielectric versus a good conductor is governed by the Loss Tangent. This article provides a practical guide with embedded calculation and selection tools to select the most appropriate real ground plane model below an antenna elevated or connected to ground in AN-SOF.

The Inverted V antenna is a cornerstone of HF communication, providing a space efficient and single mast supported alternative to the horizontal dipole. This guide examines the critical influence of the antenna height above ground on its radiation pattern. Furthermore, we demonstrate how to use AN-SOF to accurately model the feedpoint at the antenna apex, enabling precise VSWR and gain predictions, an advantage often absent in traditional simulation tools.

In this article, we dive deep into near-field calculations to establish RF exclusion zones. By understanding near-field and far-field regions, occupational vs. public exposure, health impacts, and practical methods, we ensure compliance with EMF guidelines and safeguard human health.
