LENS FOR SCANNING ANGLE ENHANCEMENT OF PHASED ARRAY ANTENNAS

摘要

A method and apparatus for a negative index metamaterial lens. The method is used for creating a negative in-dex metamaterial lens for use with a phased array antenna. A de-sign is created for the negative index materials lens that is capa-ble of bending a beam generated by the phased array antenna to around 90 degrees from a vertical orientation to form an initial design. The initial design is modified to include discrete compo-nents to form a discrete design. Materials are selected for the discrete components. Negative index metamaterial unit cells are de-signed for the discrete components to form designed negative in-dex metamaterial unit cells. The designed negative index meta-material unit cells are fabricated to form fabricated designed neg-ative index metamaterial unit cells. The negative index metamate-rial lens is formed from the designed negative index metamaterial unit cells.
