A unit cell for increasing isolation between antennas makes use of a multi-layer configuration where a top layer is formed into the shape of a notched square with a plurality of vias, positioned atop a solid layer having a lower di-electric constant than the top layer, which in turn is positioned above a metallic layer. In some embodiments, further third and fourth layers are positioned on the other side of the metallic layer to create a symmetric stacking of layers. The first and fourth layers are rotated 180° from each other about an axis of symmetry. When interposed between either cross-polarized or co-polarized antennae, the unit cell absorbs electromagnetic radiation between the antennae to provide a number of different operating frequency bands. The isolation and number of frequency bands may be a function of the number and placement of vias and the size, shape and dimensions of the layers.
