My interest in magnetic loop antennas began in 2020. After reading numerous theoretical articles online, I realized that one of the key challenges with these antennas is their very narrow bandwidth, which requires precise tuning.

Motivated by this challenge and drawing on my background as a mechanical engineer, I decided to build one myself.

This endeavor was fantastic and required expertise in 3D design, electronics, and, last but not least, coding in different languages and on various platforms. It also involved utilizing polynomial mathematics—a subject I learned in school 40 years ago but had rarely used since then.

Some of you might say that my system is overengineered and full of non-value-adding features, or even that I am crazy. You are probably right, but as Steve Jobs once said

“Here’s to the crazy ones, the misfits, the rebels, the troublemakers, the round pegs in the square holes…the ones who see things differently.”

It brings a lot of joy to be crazy—believe me!

This site was created to share my learnings and results with all enthusiastic radio hams who have already built or are planning to build their own magnetic loop antenna.

Happy reading and good luck with your projects!
