  • Patent number: 10090602
    Abstract: A steerable beam antenna includes a rotatable drum having a diffraction grating surface, and a waveguide feed including first and second conductive metal bases extending axially along the length of the drum, each of the bases having an inner surface spaced from and opposed to the inner surface of the other base, and a proximal surface spaced from the drum surface by a gap. First and second parallel conductive metal plates extend distally from the first and second bases, respectively, the first and second plates having respective inner surfaces separated by an inter-plate space. First and second dielectric strips are flush-mounted on the inner surfaces of the first and second conductive metal bases, respectively, the first dielectric strip extending longitudinally along the inner surface of the first base, and the second dielectric strip extending longitudinally along the inner surface of the second base, opposite the first dielectric strip.

  • Patent number: 9698478
    Abstract: An electronically-controlled steerable beam antenna with suppressed parasitic scattering includes a feed line defining an axis x; and first and second arrays of electronically-controlled switchable scatters distributed along the axis x, each of the scatterers in the first and second arrays being switchable between a high state and a low state to scatter an electromagnetic wave propagating through the transmission line so as to form a steerable antenna beam. Each of the scatters of the second array is configured to be 180°-phase-shifted relative to a corresponding scatter of the first array. The switchable scatterers of the first and second arrays are configured into high states and low states relative to each other so as to suppress parasitic scattering of the electromagnetic wave without suppressing the steerable antenna beam.

  • Patent number: 9577342
    Abstract: A waveguide includes a dielectric substrate having first and second opposed surfaces defining a longitudinal wave propagation path therebetween; and a conductive grid on the first surface of the substrate and comprising a plurality of substantially parallel metal strips, each defining an axis. The grid renders the first surface of the substrate opaque to a longitudinal electromagnetic wave propagating along the longitudinal wave propagation path and polarized in a direction substantially parallel to the axes of the strips. The grid allows the first surface of the substrate to be transparent to a transverse electromagnetic wave having a transverse propagation path that intersects the first and second surfaces of the substrate and having a polarization in a direction substantially normal to the plurality of metal strips. A diffraction grating on the second surface allows the waveguide to function as an antenna element that may be employed in a beam-steering antenna system.

  • Patent number: 7864112
    Abstract: A beam-forming antenna for transmission and/or reception of an electromagnetic signal having a given wavelength in a surrounding medium includes a transmission line electromagnetically coupled to an array of individually controllable antenna elements, each of which is oscillated by the signal with a controllable amplitude. The antenna elements are arranged in a linear array and are spaced from each other by a distance that does not exceed one-third the signal's wavelength in the surrounding medium. The oscillation amplitude of each of the individual antenna elements is controlled by an amplitude controlling device, such as a switch, a gain-controlled amplifier, or a gain-controlled attenuator. The amplitude controlling devices, in turn, are controlled by a computer that receives as its input the desired beamshape, and that is programmed to operate the amplitude controlling devices in accordance with a set of stored amplitude values derived empirically for a set of desired beamshapes.

  • Patent number: 7777286
    Abstract: A microwave switch array includes a plurality of microwave slotlines, each of which is controlled by a semiconductor switch including a first PIN junction formed by a primary P-type electrode and a primary N-type electrode separated by the slotline. The switches inject a plasma into the slotline in response to a potential applied across the first PIN junction. Each of the switches includes a second PIN junction between the primary P-type electrode and a secondary N-type electrode, and a third PIN junction between the primary N-type electrode and a secondary P-type electrode. Metal contacts connect the primary P-type electrode and the secondary N-type electrode across second PIN junction, and the primary N-type electrode and the secondary P-type electrode across the third PIN junction. The secondary electrodes extract plasma that diffuses away from the first PIN junction, thereby minimizing the performance degrading effects of plasma diffusion.

  • Patent number: 7667660
    Abstract: A scanning antenna with an antenna element having an evanescent coupling portion includes a waveguide assembly including a transmission line, adjacent the coupling portion, through which an electromagnetic signal is transmitted, permitting evanescent coupling of the signal between the transmission line and the antenna element. First and second conductive waveguide plates, on opposite sides of the transmission line, define planes that are substantially parallel to the axis of the transmission line, each plate extending distally from a proximal end adjacent the antenna element, whereby the propagated signal forms a beam that is confined to the space between the plates and thus limited to a plane that is parallel to the planes defined by the plates. The signal coupled between the transmission line and the antenna element is preferably polarized so that its electric field component is in a plane parallel to the planes defined by the plates.
