Patents by Inventor Hussain Al-Rizzo

Hussain Al-Rizzo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Nano and micro based antennas and sensors and methods of making same
    Patent number: 8692716
    Abstract: A method of fabricating an antenna. In one embodiment, the method includes the steps of providing a substrate treated with a plasma treatment, providing a nanoparticle ink comprising nanoparticles, painting the nanoparticle ink on the substrate to form an antenna member in which the nanoparticles are connected, determining a feed point of the antenna member, and attaching an feeding port onto the substrate at the feed point to establish a contact between the feeding port and the antenna member.
    Type: Grant
    Filed: February 16, 2009
    Date of Patent: April 8, 2014
    Assignee: Board of Trustees of the University of Arkansas
    Inventors: Alexandru S. Biris, Hussain Al-Rizzo, Taha Elwi, Daniel Rucker
  • Circularly polarized microstrip antennas
    Patent number: 8466838
    Abstract: The present invention in one aspect relates to a circularly polarized antenna having a conductive ground layer, a conductive patch and a dielectric substrate formed between the conductive ground layer and the conductive patch. The conductive patch formed in a square shape with four equal sides and has four square slots with each formed in the central portion of each side, and two rectangular slots orthogonally formed in the central area of the square such that one rectangular slot is aligned with one diagonal of the square, the other rectangular slot is aligned with the other diagonal of the square, and the junction of the two rectangular slots is coincident with the geometrical center of the square.
