The Precision Engine for Antenna Design

AN-SOF is a specialized simulation environment for the high-fidelity modeling and analysis of complex antenna systems. Built on the Conformal Method of Moments (CMoM) with Exact Kernel, it provides engineers and researchers with a numerically superior tool for validating designs before they reach the prototype stage.

From academic research to industrial RF engineering, AN-SOF provides the accuracy needed to bridge the gap between theoretical modeling and real-world performance.

Core Areas of Application

  • Precision Wire Modeling: Dipoles, Monopoles, Yagi-Uda, and Log-Periodic arrays.
  • Complex Geometries: Helices, Spirals, Loops, and Fractal antennas.
  • Environmental Analysis: Modeling antennas above lossy ground planes and radial wire ground screens.
  • Planar Structures: Single-layer microstrip patch antennas and passive circuits.
  • EMC & PCB Analysis: Evaluating radiated emissions from Printed Circuit Boards (PCBs) and Electromagnetic Compatibility (EMC) compliance.
  • Broadcasting & Telecom: High-power array design and non-radiating network analysis.

The Numerical Edge: CMoM vs. Traditional MoM

Beyond the “Thin-Wire” Approximation

Most traditional MoM (Method of Moments) codes rely on linear approximations and the “thin-wire” kernel, limitations that introduce significant inaccuracies in complex designs. AN-SOF utilizes the Conformal Method of Moments (CMoM) with an Exact Kernel formulation, specifically engineered to overcome the common failures of legacy simulation tools.

Illustration depicting the seven limitations overcome by AN-SOF's Conformal Method of Moments in antenna design.

7 Critical Limitations Solved by AN-SOF:

  1. True Curvature: While traditional codes struggle with curved wires (helices, loops, spirals), CMoM maintains geometric fidelity for superior accuracy.
  1. Precision Wire Spacing: Simulate close parallel wires and transmission lines without the “quarter-segment” separation constraint.
  1. Angular Convergence: Eliminate inaccuracies in wire grids and right/acute bends where traditional MoM fails to converge.
  1. Broad-Spectrum Stability: Model from quasi-electrostatic regimes (60 Hz) to microwave frequencies without “short segment” errors.
  1. Surface Current Fidelity: Move beyond the thin-wire approximation; AN-SOF accounts for surface current on thick wires for real-world precision.
  1. Seamless Tapering: Eliminate non-physical discontinuities in designs with varying segment radii.
  1. Ground Plane Accuracy: Achieve stable input impedance and accurate efficiency for antennas in close proximity to lossy ground.

The Result: Faster Convergence, Absolute Precision.

By implementing a numerically exact formulation, AN-SOF reduces the computational overhead while increasing the reliability of your data.
