How to make Fractal Antennas

Fractal Antenna Design


Fractal Antennas

Fractal antennas are aerials whose design is based on the fractal geometric shape, typically generated by computer programs, feature a compact size, wideband and good performances.

These antennas are usually flat and are used mainly in very high frequencies, therefore are ideal for use in mobile, military and security applications.

Chip Cohen W1YW (N1IR) one of the first to implement fractals in antenna modelling, patented the design and founded the Fractal Antenna Systems company.

HF Fractal antennas offer a very compact size, a good performance and a large bandwidth, but are very unusual aerials. According to our investigation, the web does not offer much information on home-brewing these kind of antennas, especially for high frequency bands.

According to those who experienced home-brewing this antenna, it’s considered a heavy antenna, with a large diameter boom and  wind-load issues to be considered.

If you want to make your own fractal antenna for HF bands, or simply learn more on this particular design, you might want to have a look at these projects.


fractalA fractal is a never-ending pattern. Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop.
