Antenna Simulator


AN-SOF is a comprehensive software tool for the modeling and simulation of antenna systems and general radiating structures. It can be used

- to learn more about antennas
- to get insight into the behavior of a particular antenna
- to design better antennas
- to predict antenna performance
- to tune for performance
- to try several possibilities before building the real model

The program is based on an improved version of the so-called Method of Moments (MoM) for wire structures. The modeling of the structure can be performed by means of the AN-SOF specific 3D CAD interface. Electromagnetic fields, currents, voltages, input impedances, consumed and radiated powers, gain, directivity, and several more parameters can be computed in a frequency sweep and plotted in 2D and 3D graphical representations.

Antenna Modeling & Design

High-end EM Simulations

AN-SOF is intended for solving problems in the following areas:

- Antenna analysis and design, including microstrip and patch antennas.

- Radiated emissions from printed circuit boards (PCB).

- Susceptibility analysis of PCBs.

- Electromagnetic Compatibility (EMC) applications.

- Multiconductor transmission lines.

- Passive circuits and general non-radiating networks.

Easy to use

The main purpose of AN-SOF is making simulation easy and accessible to a wide audience, so the software has been designed for everyone interested in Electromagnetics and Electronics. No previous expertise in electromagnetic simulation is required to begin using this tool. AN-SOF is frequently used by students, teachers, technicians, engineers, amateur radio hams, and everyone involved in the research and design of metallic antennas and passive circuits, from the very low frequency range to microwaves, as well as those dealing with radio engineering, microwaves, radar techniques, electromagnetic compatibility and communications.

The program can also be used for teaching purposes, primarily for research activities at the postgraduate level, but also for demonstration of antenna and scatterer phenomena.

Several features

AN-SOF is an antenna simulation software that allows us

- to describe the geometry of the antenna
- to choose construction materials
- to describe the environment and ground conditions
- to describe the antenna height above ground
- to analize the radiation pattern and front-to-back ratio
- to plot directivity and gain
- to analize impedance and SWR (Standing Wave Ratio)
- to predict bandwidth 

and to get several more parameters and plots.
