Abstract
A tunable passive anti-jamming antenna array system and method for 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 and interfering signals to disrupt the interference signals and reduce the electromagnetic energy, interference, and noise reaching the intended receiving antenna unit.
Claims20
A passive antenna system for suppressing electromagnetic interference signals comprising:
- an electromagnetic energy source;
- a receiving antenna electrically connected to a receiver or transceiver for receiving electromagnetic energy from said electromagnetic energy source;
- and
- at least one passive open circuited antenna positioned between said receiving antenna and the electromagnetic interference signals, wherein said at least one passive open circuited antenna is not electrically connected to said receiving antenna other than via an electrical ground.
A method for suppressing electromagnetic interference signals comprising:
- utilizing an electromagnetic energy source and a receiving antenna connected to a receiver or transceiver to transmit electromagnetic signals between the electromagnetic source and the receiver or transceiver;
- and
- placing at least one passive open circuited antenna between the receiving antenna and the electromagnetic interference signals, wherein the at least one passive open circuited antenna is not electrically connected to the receiving antenna other than via an electrical ground.
