Technological advances and the increasing availability of unmanned aerial vehicles, known as drones, have brought numerous benefits to various sectors, including filming, security, delivery and entertainment. However, at the same time, challenges related to theirs also appeared
misuse, such as privacy violations, unauthorized surveillance, and even security threats. For this reason, devices known as drone jammers have been developed, the purpose of which is to disable communication between the drone and its operator,
forcing it to make an emergency landing or return to its starting point. The drone jammer works on the principle of electromagnetic jamming of radio frequency signals that the drone uses to communicate with the remote control or GPS satellites. Most
modern drones rely on frequencies of 2.4 GHz and 5.8 GHz for communication and video signal transmission, while GPS signals are usually in the range of 1.2 GHz to 1.6
GHz. By allowing strong electromagnetic radiation within these frequencies, a jammer can disrupt communication between a drone and its operator, causing different effects depending on the drone model and its safety protocols.
