AN-SOF 9.50 Release: Streamlining Polarization, Geometry, and EMF Calculations

We’re thrilled to announce AN-SOF 9.50, packed with user-requested enhancements. Improved geometry input, simplified polarization analysis, and new EMF compliance tools make antenna design easier and more precise than ever. Upgrade your design process with AN-SOF 9.50!

We’re excited to announce the release of AN-SOF 9.50, featuring enhancements requested by our valued users. We’ve listened to your feedback and made key improvements to streamline your antenna design process, particularly in polarization analysis, geometry input, and EMF compliance calculations.

What’s New in AN-SOF 9.50?

Enhanced Geometry Input

• Helix Primitive Updates: Design axial mode helices and QHAs (Quadrifilar Helical Antennas) more easily by entering values for Diameter, Pitch Angle, and Wire Length.
• New “GB” Command: Import and export wire arcs using this new command, which is more versatile than the traditional “GA” command and simplifies the modeling of curved structures—no more complex coordinate transformations! It’s perfect for advanced antenna designs, like those in our Omni Double Bi-Quad post for 2.4 GHz.
• Improved Wire Recognition: Wire numbers from the Tabular Input window are now shown directly on the workspace, making editing faster and more intuitive for former NEC users.
• Advanced Editing Options: With enhanced Scale Wires and Copy Wires commands, you can easily stretch, compress, or duplicate wire groups. These features simplify the creation of designs like LPDAs and circular arrays.

Simplified Polarization Analysis

• All radiation pattern metrics—power density, directivity, gain, etc.—are now easily decomposed into Vertical (VP), Horizontal (HP), Right-Handed (RHCP), and Left-Handed (LHCP) components.
• A new toolbar on all graphs lets you quickly toggle between these polarization components, making analysis more intuitive than ever.

New Features for EMF Compliance Calculations

• Power Density Calculations: Power density is now calculated in the near-field region, displayed in both 2D and 3D, helping to determine exclusion zones around antenna installations. Stay tuned for a complete tutorial on this feature.
• Time-Averaged Power Settings: In the Tuner tab, you can now set Transmit Mode, Duty Cycle, and Time Transmitting parameters, allowing for more accurate calculations of EIRP, E-field, H-field, and power density. These settings help ensure compliance with exposure regulations.
