Abstract
An antenna assembly minimizes reflection from a proximate reflective surface over a wide band and over a wide range of incident angles as a multi-layer diffuser. The planar structure includes first and second planar layers, each layer having first areas that are more conductive than second areas. Each area has a periphery that extends along a grid of first and second sets of parallel lines so that each area comprises one or more contiguous elements defined by the lines. The first and second areas are configured and arranged so that the planar layer can communicate electromagnetic energy wirelessly in a specific direction to the planar layer when an electrical connection is made to the first area(s). The first planar layer is positioned on top of the second planar layer. The respective second areas of second planar layer aligned with a corresponding second area of the first planar layer.
