Metarray.wTM is an ultra-compact antenna array for WiMax MIMO applications. A version of the product also includes 802.11n bands. 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 Technology TM ensures that each compact antenna element delivers efficiencies similar to free space while simultaneously providing high MIMO gain - with drastically reduced spacing between the antenna elements.
