Most varieties of fractal antennas are so-called “fractal element antennas”.

As fractals can be used as counterpoises, loads, ground planes, and filters, all parts that can be integrated with antennas, they are considered parts of some antenna systems and thus are rractales in the context of fractal antennas. With this baseline, he has successfully guided the company through the rapidly changing currents of the wireless industry.
