  • Continuous antenna arrays
    Patent number: 11217898
    Abstract: A continuous antenna array includes a plurality of antenna elements whose opposing electrodes create an electric field that excites polarization currents in an enclosed dielectric. Each of the antenna elements comprises one or more stripline feeds configured to provide a flat form factor and apply a signal with controlled phase differences between the plurality of antenna elements.

  • Superluminal antenna
    Patent number: 9948011
    Abstract: A superluminal antenna element integrates a balun element to better impedance match an input cable or waveguide to a dielectric radiator element, thus preventing stray reflections and consequent undesirable radiation. For example, a dielectric housing material can be used that has a cutout area. A cable can extend into the cutout area. A triangular conductor can function as an impedance transition. An additional cylindrical element functions as a sleeve balun to better impedance match the radiator element to the cable.
