Learn the essentials of the antenna near field! This guide explains key concepts for ham radio operators, from reactive fields to EMF safety, helping you better understand antenna radiation and ensure compliance. Ideal for both beginners and experienced hams alike!

In today's wireless world, ensuring Electromagnetic Field (EMF) compliance is crucial for protecting individuals from potential harmful effects of RF exposure. Join us as we explore the influence of antenna configurations, ground planes, and feed lines on far-field EIRP values, ensuring you possess the tools to navigate the complexities of EMF compliance effectively.

In this article, we dive deep into near-field calculations to establish RF exclusion zones. By understanding near-field and far-field regions, occupational vs. public exposure, health impacts, and practical methods, we ensure compliance with EMF guidelines and safeguard human health.

Discover how the Wave Matching Coefficient (WMC) redefines near-far field boundaries. Using a 20 dB threshold, we uncover new distances for elementary antennas and a consistent method to define non-spherical boundaries for antennas of any size or complexity relative to the wavelength.

Unleash the power of your AN-SOF simulations! This article explores the software's data export features, enabling you to seamlessly transfer results to spreadsheets for further analysis, report generation, and clear communication of your antenna design findings.

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 […]

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: http://www.g3tvu.co.uk/Antenna_Plots.htm Versions 1 (azimuth) and 3 (azimuth and elevation) described in the link above have been implemented in AN-SOF. Exporting an Azimuth […]

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.

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.
