Get Ready for the Next Level of Antenna Design.

Folded Dipoles, 20m Tuning, and Optimization in Action

Welcome to a new edition of Antennas and Beyond! In this issue, we break down the folded dipole—its structure and impedance behavior.
We walk through a complete workflow for modeling, feeding, and tuning a dipole for the 20-meter band—ideal for getting on the air with precision.
And we apply the Nelder-Mead method to optimize antenna designs using AN-SOF and Scilab, showing how smart algorithms can fine-tune your results.

Let’s get started!
