We investigate an interference suppression in a system with a conductor wall between two antennas. We evaluated the interference suppression by putting electromagnetic band gap (EBG) structures on the conductor wall and blocking surface waves. A huge calculation cost is required to simulate a large scale propagation model including the EBG structures. In this paper, the Interference between antennas is calculated by using the angular spectrum method and the surface impedance of the EBG structures. In a system with 40 wavelengths square EBG structures, the error between the calculation result and the measurement result is 2.3 dB. We evaluate the relationship between the area of the EBG structures and the interference suppression. It is clarified that increasing the occupied area ratio of the EBG structures between antennas and reducing the loss of the EBG structures are effective to increase the interference suppression. |
