Traditional coil inductance calculations often rely on simplified approximations. AN-SOF offers a more accurate approach by considering factors like non-uniform magnetic fields, conductor losses, and complex coil geometries. By using AN-SOF, you can obtain precise inductance values, visualize magnetic field and current distributions, to improve your coil designs.

We are happy to share an interesting project by one of our AN-SOF users: @PoweredMeshtasticEurope. He demonstrates how to build your own helix high gain directional antenna for the Meshtastic frequency range, from theory to reality.

The Quadrifilar Helix (QFH) antenna, with its unique design and circular polarization, ensures efficient NOAA satellite signal reception. This article explores the history, key characteristics, and practical modeling of QFH antennas using AN-SOF, providing valuable insights for RF engineers and enthusiasts.
