Metarray.nTM is an ultra-compact antenna array for 802.11n MIMO applications. It is composed of metamaterials, a new class of materials that exhibit properties not found in natural materials. These unique properties enable a 20x reduction in MIMO antenna and array size with no trade-offs in performance. Rayspan's MTM TechnologyTM ensures that each compact antenna element delibers efficiencies similar to free space while simultaneously providing high MIMO gain - with drastically reduced spacing between the antenna elements.
