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.

In this article, we provide an overview of various numerical methods used in Computational Electromagnetics (CEM), with a special focus on antenna simulation methods such as FDTD, FEM, MoM, CMoM, FMM, MLFMM, FVTD, GO, GTD, UTD, PO, PTD, and DDM.

Revolutionize antenna modeling with our simplified method. Accurately simulate 2.4 GHz wheel antennas for optimal performance.

Discover a simple yet precise method for modeling microstrip antennas on ungrounded dielectric substrates.

AN-SOF introduces an innovative method based on James R. Wait theory to accurately compute ground losses, improving monopole antenna design. Explore the validated model for LF/MF radio masts.

Discover the vital role of historical theoretical results alongside advanced numerical calculations in accurately approximating current distribution on linear antennas.

We explore the concepts of absolute wave impedance and wave matching coefficient (WMC) as practical alternatives to determine a useful boundary between the near and far field regions of an antenna.

This article validates AN-SOF’s results against the IEC FDIS 62232 standard by replicating an RBS panel antenna model with nine dipole radiators. The successful validation highlights AN-SOF’s ability to deliver highly accurate results, even with relatively simple models.

This article presents a comprehensive comparison between AN-SOF's dipole antenna simulations and the renowned King-Middleton second-order solution. Through rigorous analysis and numerical experiments, we validate the accuracy and reliability of AN-SOF in predicting dipole antenna input impedance.
