Microstrip grid array fed against an EBG

A new way to use an electromagnetic band gap structure for a particular antenna application is presented. A prototype microstrip grid array is shown to be capable of being fed against the surface of an electromagnetic band grap structure such that the array and feed are kept separate from the ground plane that is typically required for feeding. The array can then be placed on any surface suitable enough to act as a ground plane. Simulations of the baseline and prototype are presented.
