  • Tailorable dielectric material with complex permittivity characteristics
    Patent number: 8790773
    Abstract: A dielectric material includes a network of nanosubstrates, such as but not limited to nanotubes, nanosheets, or other nanomaterials or nanostructures, a polymer base material or matrix, and nanoparticles constructed at least partially of an elemental metal. The network has a predetermined nanosubstrate loading percentage by weight with respect to a total weight of the dielectric material, and a preferential or predetermined longitudinal alignment with respect to an orientation of an incident electrical field. A method of forming the dielectric material includes depositing the metal-based nanoparticles onto the nanosubstrates and subsequently mixing these with a polymer matrix. Once mixed, alignment can be achieved by melt extrusion or a similar mechanical shearing process. Alignment of the nanosubstrate may be in horizontal or vertical direction with respect to the orientation of an incident electrical field.
    Type: Grant
    Filed: July 16, 2008
    Date of Patent: July 29, 2014
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
    Inventors: Kenneth L. Dudley, Holly A Elliott, John W. Connell, Joseph G. Smith, Sayata Ghose, Kent A. Watson, Donavon Mark Delozier
  • Antenna with dielectric having geometric patterns
    Patent number: 8508413
    Abstract: An antenna includes a ground plane, a dielectric disposed on the ground plane, and an electrically-conductive radiator disposed on the dielectric. The dielectric includes at least one layer of a first dielectric material and a second dielectric material that collectively define a dielectric geometric pattern, which may comprise a fractal geometry. The radiator defines a radiator geometric pattern, and the dielectric geometric pattern is geometrically identical, or substantially geometrically identical, to the radiator geometric pattern.
