  • 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.

  • Publication number: 20190067831
    Abstract: A superluminal antenna element having a transmission line feed, and an array comprising a plurality of such antenna elements, is presented. In one example, the antenna element includes a dielectric base portion having a cutout area, a mode transition element coupled to the cutout, a stripline transmission line connected to the mode transition, and a dielectric radiator element disposed within the cutout. The cutout of the dielectric base portion has first and second pluralities of steps arranged in opposing pairs. The mode transition element is located below and coupled to the cutout area of the dielectric base portion. The dielectric radiator element is mounted within the cutout area in an opposing pair of steps. Imposing a time-varying signal on the dielectric radiator element by way of the transmission line, mode transition element, and stepped cutout induces a polarization current in the dielectric radiator element.

  • Patent number: 9548536
    Abstract: An antenna may include a volume polarization current radiator and a feed network. The volume polarization current radiator, includes a dielectric solid (such as a dielectric strip), and a plurality of closely-spaced excitation elements (24), each excitation element (24) being configured to induce a volume polarization current distribution in the dielectric solid proximate to the excitation element when a voltage is applied to the excitation element. The feed network is coupled to the volume polarization current radiator.
