Abstract :
The bistatic radars consist of transmitting antenna and receiving antenna. There antennas are placed side by side. However transmitted pulse from transmiting antenna is directly received by the receiving antenna. Therefore, if the radar and the target are close, transmitted pulse and wave which reflected from the target overlap each other and artificial image occurs. On the other hand, EBG (Electromagnetic Band-Gap) structure that is one of metamaterial reduces the electromagnetic coupling in specific frequency. This study shows that inserting EBG structures between the transmitting antenna and the receiving antenna reduce the artificial image.
