The guides describe how to set up a simulation, draw wires, run the calculations, and display the results.

Quick Start Guide

An antenna model is a representation of a real-world antenna in a computer program. This kind of model should not be confused with a scale model that sometimes is built to measure the radiation characteristics of an identical antenna with a larger physical size...

AN-SOF Overview

AN-SOF is a comprehensive software tool for the modeling and simulation of antenna systems and radiating structures in general. AN-SOF is intended for solving problems in the following areas...

Preferences

Preferences include the unit system to be used for showing input and output data, the workspace appearance, and several miscellaneous options. Preferences can be accessed via...

Tools in the Workspace

The background of the workspace can be white or black. When a white (black) background is chosen, all wires will default to black (white) unless a different color is specified for certain wires. The workspace color can be set by going to...

File Formats

When a project is saved in AN-SOF, multiple files that have the same name as the project are saved. Each file has a unique extension that...

Conformal Moment Method

In the traditional Method of Moments (MoM) the structures to be modeled are divided into straight wire segments. Straight segments fit well the shape of linear antennas like dipoles and arrays constructed using dipoles. However, there are many antennas...

The Setup Tab

The simulation parameters can be set in the Setup tabsheet. This page has the following panels: Frequency, Environment, Far-Field, Near-Field, Excitation, and Settings...

Specifying the Frequencies

The Frequency panel has three options: Single, List and Sweep. By choosing one of these options the simulation can either be performed for a single frequency, for frequencies taken from a list or for a frequency sweep...

Defining the Environment

Go to the Setup tab in the main window and select the Environment panel. The relative permittivity and permeability of the surrounding medium can be set in the Medium box, Fig. 1. Four options are available for the ground plane...

Far Field Parameters

The far field can be computed after having calculated the current distribution previously. Thus, the parameters set in the Far-Field panel have no effect in the determination of the currents and can be modified at any time. However, the far field must be...

Near Field Parameters

The near field can be computed after having calculated the current distribution previously. Thus, the parameters set in the Near-Field panel have no effect in the determination of the currents and can be set at any time. However, the near field must be recalculated every...

The Settings Panel

Go to the Setup tab in the main window and select the Settings panel, Fig. 1. The accuracy of the integrals involved in the calculations can be set in the Settings panel. The Quadrature Tolerance is the error in the evaluation of...

Types of Wires

AN-SOF has different types of wires. Each wire type has its own geometrical parameters, attributes and materials that can be set in a specific Draw dialog box. This dialog box allows us...

Wire Attributes

The Attributes page belongs to the Draw dialog box of the chosen wire type, Fig. 1. In the Attributes page the following attributes can be specified...

Wire Materials

The Materials page belongs to the Draw dialog box of the chosen wire type, Fig. 1. In the Materials page the following attributes can be specified...

Enabling/Disabling Resistivity

If wires with non-zero resistivity have been drawn previously and the whole structure must now be considered as a perfect electric conductor, all resistivities can be disabled...
