Equivalent Circuit of a Balun in AN-SOF.

The Equivalent Circuit of a Balun

A balun can be implicitly modeled in AN-SOF using an equivalent generator, as the figure below shows. Since voltage sources admit an internal impedance, we can adjust its resistance value to match the antenna input resistance.

Radiating towers or radio masts can be modeled in AN-SOF with a high degree of detail, as shown in the figure below. Since we already know the omnidirectional shape of the radiation pattern, what interests us is to calculate electric field values at ground level for a given input power.

How to Merge Projects

Wires can be imported into AN-SOF from another AN-SOF project, so wire structures of different projects can be merged in a single project.

To discover errors in the wire structure we can use the following functions in the AN-SOF main menu > Tools option.

Yagi-Uda antenna analysis via element spacing script.

Element Spacing Simulation Script for Yagi-Uda Antennas

Categories: Modeling Guidelines, Scripts

This guide explains how to run a script in Scilab to simulate a 3-element Yagi-Uda antenna and get the results as a function of the spacing between the elements. A second script allows us to plot the antenna gain versus element spacing.
