AN-SOF Antenna Simulation Software

The image below shows my preliminary results experimenting with DeepSeek-V3 to assist in designing a 3-element Yagi-Uda array for the 10 m band. I requested an output file in NEC format to import into AN-SOF Antenna Simulator. The image displays three iterations where I requested modifications to improve the Front-To-Back (F/B) ratio.

Key Takeaways So Far:

✅ It’s important to start with general requests about the antenna design before refining them with more specific requirements.

✅ In this example, I began with broad prompts:
📏 What are the recommended element lengths and spacings for a Yagi-Uda antenna?
📏 Could you recommend the element lengths and spacings for a 3-element Yagi-Uda antenna for the 10 m band?

✅ Finally, I prompted the AI to generate a complete NEC model 📝.

I’ll be sharing more details soon!

Dive deep into the world of RF compliance with our latest article: Evaluating EMF Compliance – Part 2: Using Near-Field Calculations to Determine Exclusion Zones. Discover practical methods and insights on ensuring safe RF exposure. Perfect for DX enthusiasts and RF safety professionals!

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.

These online RF calculators assist with conversions (like frequency to wavelength, Watts to dBm, VSWR to reflection coefficient, etc.) and offer easy calculations for antenna power density, near-far field boundary, line of sight, radio horizon, and more.

The calculators are organized into three categories: 

• Conversion Calculators >
• Antenna Propagation Calculators >
• Antenna Component Calculators >

Just fill in the fields, hit Calculate, and you’ll get your results instantly.

We hope you find these tools useful as a complement to AN-SOF!

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.

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!
