Setting the Radiation Pattern Center
From the far field point of view, the whole structure of an antenna and its surroundings is reduced to a single point at the origin (X,Y,Z) = (0,0,0).
H-Field Option in Preferences
We see that most of the time we are interested in calculating only the E-field in antenna projects when we are talking about the near field. For this reason, we have added an option to enable or disable the automatic calculation of the H-Field.

On the Modeling of Radio Masts
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.
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.

Export Radiation Patterns to MSI Planet
AN-SOF allows us to export radiation patterns to a *.msi file which can then be imported into the Planet propagation simulation tool developed by MSI. The antenna pattern files in MSI format are described in this link >. 1. The far-field of an antenna model must be computed previously using the Full 3D option in […]
Plotting Level Curves
The Scilab script shown in this video is ready to use together with AN-SOF. It allows us to plot level curves or isocontours of a field pattern.
Export Radiation Patterns to Radio Mobile
AN-SOF allows us to export radiation patterns to a *.ant file which can then be imported into the Radio Mobile (RM) propagation software. The antenna pattern files recognized by RM are described here: Versions 1 (azimuth) and 3 (azimuth and elevation) described in the link above have been implemented in AN-SOF. Exporting an Azimuth […]
How to Export Data and Plots
It is important to be able to export data so we can write reports and share our progress with colleagues. Simulation results can be exported to CSV (Comma Separated Values) files, where data are saved in tabular format.
Scilab Script for Plotting Level Curves
The Scilab script shown in this video, Isocontours script, is ready to use together with AN-SOF. It allows us to plot level curves or isocontours of a field pattern.
Adjusting the Color Bar in AN-3D Pattern
It is important to have control over the scales of the graphs for a better presentation and interpretation of the results. We can adjust the maximum and minimum values of the color bar in AN-3D Pattern to obtain increments in multiples of 5 or the value we want.
