ABSTRACT:
A method and apparatus including, in some embodiments, a first conductor plane, a first array of periodically distributed co-planar conductive patches, each patch in the first array being connected to the first conductor plane, a second conductor plane separated from and parallel to the first conductor plane, and a second array of periodically distributed co-planar conductive patches, with each patch in the second array being connected to the second conductor plane, and where the first array and second array of periodically distributed co-planar elements are distributed in an overlapping and alternating adjacency.
