  • Composite substrate for a waveguide and method of manufacturing a composite substrate
    Patent number: 11394097
    Abstract: Composite substrate for a waveguide for RF signals having a signal frequency, wherein said composite substrate comprises at least a first layer of dielectric material and a second layer of dielectric material, and at least one conductor layer of an electrically conductive material arranged between said first layer and said second layer, wherein a layer thickness of said at least one conductor layer is smaller than about 120 percent of a skin depth of said RF signals within said electrically conductive material of said conductor layer.
    Type: Grant
    Filed: April 27, 2018
    Date of Patent: July 19, 2022
    Assignee: NOKIA SOLUTIONS AND NETWORKS OY
    Inventors: Senad Bulja, Rose Fasano Kopf, Pawel Rulikowski, Majid Norooziarab
  • Electrochromic reflectarray antenna
    Patent number: 10903568
    Abstract: An antenna element includes a patch antenna and a microstrip line separated by an electrochromic material to tune the element. A reflectarray of a plurality of antenna elements is formed on a substrate. The dielectric permitivities of the electrochromic material may be controlled both during manufacture and during operation of the antenna to provide a phase shift to the antenna elements and beamform a signal radiated by the antenna. A bias line may be used to change a shape, direction or circular polarity of a beam radiating from the antenna.
