We’re thrilled to announce AN-SOF 9.50, packed with user-requested enhancements. Simplified polarization analysis, improved geometry input, and new EMF compliance tools make antenna design easier and more precise than ever. Upgrade your design process with AN-SOF 9.50!
Did you know that AN-SOF can be used as a coil inductance calculator?
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.
After the addition of the Feeder and Tuner in AN-SOF 9, I’ve received several inquiries about configuring the various parameters within these tabs. While offering unparalleled flexibility for modeling diverse scenarios, this complexity has presented a challenge in providing clear explanations. Here are frequently asked questions related to the Feeder and Tuner features.
I hope these answers helps clarify these matters.
Thank you for your continuous feedback!

At the request of a client and follower of our section The Ham’s Corner, I’ve been working on a Lazy-H antenna model for the 10m band. The Lazy-H is a 4-element broadside array, offering an estimated gain increase of about 6 dB over a single element. I’ll be publishing an article on this antenna soon.
Stay tuned!

Helping a customer solve a real-world problem is incredibly rewarding!
Recently, we worked with a client building Omni Double Bi-Quad antennas for 2.4 GHz who was facing a mismatch between simulations and real-world performance. The culprit? Rounded corners, not represented in the model. By creating a script that considered rounded corners, we were able to achieve a more accurate simulation, leading to a new AN-SOF command called GB.
‘GB’ simplifies creating rounded corner models, saving time and improving simulation accuracy compared to the older ‘GA’ NEC command. Stay tuned for an upcoming tutorial on this model!
Today marks a significant milestone in the journey of AN-SOF Antenna Simulator – it’s been 12 years since I launched the very first version! 🎉
Back in 2002, I dedicated countless hours (and years) to develop a tool that would empower antenna designers and enthusiasts alike. In 2012, I officially launched version 1.0, and today, I’m excited to share a nostalgic screenshot of that initial version.
As we celebrate this anniversary, I want to extend my heartfelt thanks to each of you for being part of this incredible journey. Whether you’re an RF engineer, radio amateur, professor, or hobbyist, your contributions have helped shape AN-SOF into the powerful tool it is today.
Thank you for your unwavering support!
Best regards,
Tony Golden

AN-SOF DX is tailored to be accessible and affordable for individuals, not businesses.
If you are interested in AN-SOF DX, drop us a message or email to learn more or request a quotation.
Let’s elevate your antenna simulation experience together!
The Extended Double Zepp (EDZ) antenna offers higher gain than a half-wave dipole, but matching to 50-Ohm coax is difficult. This article explores a phased array design using two EDZs for directional radio transmission, achieving good gain and easier impedance matching.
Exciting update! AN-SOF 8.90 is here with features like “Segments per Wavelength,” enhanced wire scaling, TL command import/export, and faster current distribution algorithms. Elevate your antenna simulations!
In today’s wireless world, ensuring Electromagnetic Field (EMF) compliance is crucial for protecting individuals from potential harmful effects of RF exposure. Join us as we explore the influence of antenna configurations, ensuring you possess the tools to navigate the complexities of EMF compliance effectively.
Revolutionize antenna modeling with our simplified method. Accurately simulate 2.4 GHz wheel antennas for optimal performance.
From version 8.20, the AN-SOF calculation engine has successfully completed validation for accuracy in accordance with the standard IEC FDIS 62232. This standard outlines guidelines for calculating radio-frequency field strength and specific absorption rate (SAR) in the vicinity of radiocommunication base stations (RBS) to assess the potential human exposure.
The Front-to-Rear ratio is a crucial factor in determining the directional performance of your antenna. AN-SOF can display this ratio in various forms. Discover the difference between the Front-to-Rear and Front-to-Back ratios in this article.
