Abstract (en)
[origin: WO2009120237A1] A tunable passive direction finding and anti-jamming antenna array system and method for determining a location of an electromagnetic interference signal source while minimizing the effects of electromagnetic interference in radio frequency antenna systems. The system and method utilize an external array of passive open circuited antennas strategically arranged between an intended receiving antenna unit or system and interfering signals to disrupt the interference signals and reduce the electromagnetic energy, interference, and noise reaching the intended receiving antenna unit or system, as well as determine the direction of an interference signal.
