Modeling of an ultra-wideband GHz range antenna with recursive topology

For decades the development of telecommunications devices shows an inspiring progress. Nowadays, a wide range of multifunctional wireless telecommunications devices with small weight and size characteristics is being developed, since these are portable devices. One of the most important elements of such a device is the antenna. The antenna has a number of conflicting requirements: a wide frequency band, compact size, simple manufacturing technology, low price, the ability to work in several frequency bands, etc. One of the promising types of ultra-wideband antennas with a high gain is fractal antennas with a recursive topological pattern.
