...The use of an EBG AMC structure as a substrate for a low-profile conformal antenna is one particular application of interest, and by aligning the resonant frequency of the antenna with the band gap of the EBG surface it is possible to improve antenna performance and reduce surface waves within the substrate [15]–[17]....

...The AMC structure has also been shown to reduce the effects of unwanted surface waves, thereby providing a means for achieving more desirable antenna radiation patterns and reduced coupling in an array environment [15]–[17]....
