Abstract :
The bi-static radars consist of transmitting antenna and receiving antenna. The antennas are placed side by side. However transmitted pulse from transmitting 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 are observed to 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 proposed novel bi-static radar antenna that inserting EBG structures between the transmitting antennas.
