The dipole radiation of a charged particle moving along a closed fractal trajectory with constant velocity is studied. It is found that the spectrum intensity of the radiation is displaced to the high frequency region when reducing the spatial scale

In recent years, the electromagnetic environment has radically changed worldwide because of numerous sources of high-power electromagnetic signals, which interfere with information-carrying signals and, thereby, considerably distort them. As a result
