Highly concentrated energy signal antenna jammer

Antenna jammer radiate jamming signals at opponents, blocking receivers with highly concentrated energy signals. The main disadvantage of this technique is that the jammer spreads its power over multiple frequencies, making it relatively weak on a single frequency.

While “interference” generally describes unintentional forms of disruption during wireless communications, “jamming” describes the deliberate interference with or blocking of such communications.

Currently, there are several countermeasures against interference. Similar to jamming techniques, these countermeasures have varying degrees of effectiveness. In addition, specially designed anti-jamming antennas are already available. EW developments continue to evolve as new radio frequency technologies become available.
