Abstract :
Electromagnetic bandgap (EBG) material is applied in the design of reflectarray, hoping that the surface-waves could be suppressed by the frequency bandgap, and therefore, the mutual couplings between different elements in the reflectarray could be greatly reduced. To testify the benefits of the importing EBG, the phase adjusting characteristics of the array element with slots on the ground as well as the electromagnetic field distribution with and without the EBG are both presented in this paper
