Abstract
A magnetically-loaded artificial magnetic conductor surface provides enhanced bandwidth. The structure includes in one embodiment a thumbtack structure with a spacer layer that is loaded with a barium-cobalt hexaferrite based artificial magnetic material. Specifically, the geometry consists of a ground plane covered with thinly sliced ferrite tiles that are metallized and stacked. Each tile has a metal via running through its center that is electrically connected to the plated metallized surfaces. A foam spacer layer resides above the ferrite tiles. Atop the foam spacer layer rests a capacitive surface, which can be realized as a single layer array of metal patches, a multiple layer array of overlapping patches or other planar capacitive geometry.
