After decades of professional antenna modeling with tools like HFSS, CST Studio, and FEKO, Gary recently transitioned to part-time work — and needed a more accessible, cost-effective solution.

His search led him to AN-SOF, where he began exploring its capabilities through the free trial.

🗞 Quick Update: Following feedback from several users, we’ve decided to bring forward the release of the Sommerfeld–Norton ground model in the upcoming AN-SOF v10.5.

This model supports the simulation of dipoles and loops above highly dielectric grounds at very low heights—down to 0.005λ—which is sufficient for most practical applications.

Together with the existing Sommerfeld–Wait Asymptotic model (recommended for conductive grounds), AN-SOF now covers a broad range of ground conditions across typical operating frequencies.
