Antenna Simulation Software
The simulation class built for the antennas that actually matter
Measurement-Grade Conformal MoM for working RF engineers and consultants who need reliable results on complex wire, helical, and ground-plane structures, without the compromises of legacy tools or the cost of full enterprise platforms.
Most traditional Method of Moments codes still force geometric and numerical trade-offs exactly where professional work gets difficult. AN-SOF was built to remove those trade-offs. The result is higher confidence in the numbers you present and fewer surprises when the design meets the real world.
What This Class of Simulation Is For
AN-SOF is used by professionals who need measurement-grade accuracy on:
- Precision wire antennas: dipoles, monopoles, Yagi-Uda, log-periodic arrays.
- Complex curved geometries: helices, spirals, loops, and fractal structures.
- Real environments: antennas above lossy ground and radial-wire ground screens.
- Planar and hybrid structures: single-layer microstrip patches and passive circuits.
- Broadcast and high-power systems: arrays and non-radiating networks.
These are the geometries where older formulations most often lose accuracy. This is the territory Measurement-Grade Conformal MoM was designed to handle cleanly.
What Professionals Actually Need
Reliable numbers before metal is cut
Validate gain, efficiency, impedance, and patterns with a method that does not introduce unnecessary geometric error.
Realistic ground and site conditions
Model antennas near real (lossy) ground without the diverging impedance problems common in older codes.
Faster, more confident iteration
Change geometry directly, run sweeps, and refine designs without fighting the limitations of the solver.
Clear communication of results
Export clean data and visualizations that stakeholders can understand and trust.
The goal is simple: reduce the gap between simulation and measured performance so you spend less time explaining discrepancies and more time delivering working designs.
The Technical Boundary: Why This Is a Different Class
Most traditional MoM tools still rely on straight-segment approximations and the thin-wire kernel. Those choices create seven well-known limitations:
- No true curved wires: helices, loops, and spirals are forced into straight pieces.
- Spacing restrictions: parallel wires cannot be placed realistically close.
- Poor convergence at bends: right angles and sharp corners often fail.
- Short-segment limits: fine detail and low-frequency behavior become unreliable.
- Thin-wire assumption: thick conductors are treated incorrectly.
- Tapered-wire discontinuities: radius changes create non-physical jumps.
- Unstable results near real ground: horizontal wires and elevated radials produce diverging impedance.
Conformal Method of Moments with Exact Kernel removes these constraints. Geometry follows the real shape. The kernel accounts for finite radius. Ground modeling is stable. The result is higher geometric fidelity and more trustworthy current distributions on the structures professionals actually design.
This is not a minor improvement. It is a different technical class.
How the Work Feels in Practice
- Direct 3D editing. Change wire dimensions without spreadsheet gymnastics.
- Real-time visual feedback on sources, loads, and segmentation.
- Full frequency sweeps of fields, currents, and VSWR.
- Side-by-side 2D data and 3D radiation patterns.
- Scripted optimization when you need to explore many variations systematically.
The interface is built to reduce friction so the numerical advantage can actually be used on real projects.
