  • Highly-sensitive mushroom metal-dielectric sensor backed by a metal ground plane for refractive index sensing
    Patent number: 10856789
    Abstract: A nano antenna for refractive index sensing is provided that includes a silica substrate, a gold nanodisk sensor element on a first side of the substrate, where the gold nanodisk sensor element includes a silica disk disposed on the substrate and a gold disk disposed on the silica disk, where a diameter of the gold disk is greater than a diameter of the silica disk, where a height of the silica disk is greater than a height of the gold disk, and a gold layer disposed on a second side of the substrate opposite the first side, where the gold layer covers an area as large as said gold nanodisk sensor element.
    Type: Grant

  • Wide frequency band planar antenna
    Patent number: 6278410
    Abstract: The present invention provides a planar antenna having a first, outer planar conductive element and a second planar conductive element located in a hole in the outer element. At least 75% of the boundary between the hole and the first outer planar conductive element is a continuous concave smooth curve. The second planar conductive element is substantially coplanar with and surrounded by the first outer planar conductive element. At least 75% of the outer boundary of the second planar conductive element is a continuously convex smooth curve.
