QRZ Forums. I believe it was an Amateur radio guy that helped the devolopment of the fractal antenna, which is what every cell phone uses today. Since it is very broadband antenna and can be made multiband also, is it practical for HF work? In theory you could make a 80 meter antenna very small, tiny even, compared to most 80 meter antennas used today. Any thoughts or designs on a practical fractal antenna for HF work. It might just kill the tower biz if a practical HF fractal design can be worked up. W5INC , Aug 14,

A fractal antenna is an antenna that uses a fractal , self-similar design to maximize the effective length, or increase the perimeter on inside sections or the outer structure , of material that can receive or transmit electromagnetic radiation within a given total surface area or volume. Such fractal antennas are also referred to as multilevel and space filling curves , but the key aspect lies in their repetition of a motif over two or more scale sizes, [1] or "iterations". For this reason, fractal antennas are very compact, multiband or wideband, and have useful applications in cellular telephone and microwave communications. A fractal antenna's response differs markedly from traditional antenna designs, in that it is capable of operating with good-to-excellent performance at many different frequencies simultaneously.

Com currently has a very interesting item on fractal antennas. While the idea of applying fractals to the design and construction of antennas has been around for quite some time, very few hams have actually built them, and there are currently no companies building commercial fractal antennas for the ham radio market. The question, of course, is why? These advantages purportedly include wider bandwidth smaller size when compared to traditional antennas, such as verticals and dipoles. For commercial reasons, W1YW has made his articles unavailable.

In it something is. Clearly, I thank for the help in this question.

Si sbaglia. Sono in grado di provarlo. Scrivere a me in PM, ti parla.
