We are thrilled to announce the release of AN-SOF Antenna Simulator Version 11. This landmark update introduces major advancements in our core electromagnetic solver, significantly expands the modeling CAD toolbox, and delivers highly requested visualization tools for RF engineers, academic researchers, and antenna design enthusiasts.

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.
