Reconfigurable Dielectric Waveguide Antenna

View page
US Patent:
7151499, Dec 19, 2006
Filed:
Apr 28, 2005
Appl. No.:
11/116792
Inventors:
Aramais Avakian - Pasadena CA, US
Alexander Brailovsky - Irvine CA, US
Mikhail Felman - Tarzana CA, US
Irina Gordion - Irvine CA, US
Victor V. Khodos - Torrance CA, US
Vladimir I. Litvinov - Aliso Viejo CA, US
Vladimir Manasson - Irvine CA, US
Lev Sadovnik - Irvine CA, US
International Classification:
H01Q 13/00
US Classification:
343785, 343700 MS
Abstract:
A reconfigurable directional antenna for transmission and reception of electromagnetic radiation includes a transmission line aligned with and adjacent to a metal antenna element with an evanescent coupling edge having a selectively variable electromagnetic coupling geometry. The shape and direction of the beam are determined by the selected coupling geometry of the coupling edge, as determined by the pattern of electrical connections selected for physical edge features of the coupling edge. The electrical connections between the edge features are selected by the selective actuation of an array of “on-off” switches that close and open electrical connections between individual edge features. The selection of the “on” or “off” state of the individual switches thus changes the electromagnetic geometry of the coupling edge, and, therefore the direction and shape of the transmitted or received beam. The actuation of the switches may be accomplished under the control of an appropriately-programmed computer.

Beam-Forming Antenna With Amplitude-Controlled Antenna Elements

View page
US Patent:
7456787, Nov 25, 2008
Filed:
Aug 11, 2005
Appl. No.:
11/201680
Inventors:
Vladimir A. Manasson - Irvine CA, US
Lev S. Sadovnik - Irvine CA, US
Assignee:
Sierra Nevada Corporation - Spark NV
International Classification:
H01Q 3/22
H01Q 3/00
G01S 1/00
H04B 7/185
US Classification:
342375, 342372, 34235702
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.

Electronically-Controlled Monolithic Array Antenna

View page
US Patent:
7609223, Oct 27, 2009
Filed:
Dec 13, 2007
Appl. No.:
11/956229
Inventors:
Vladimir Manasson - Irvine CA, US
Vladimir I. Litvinov - Aliso Viejo CA, US
Lev Sadovnik - Irvine CA, US
Mark Aretskin - Irvine CA, US
Mikhail Felman - Tarzana CA, US
Aramais Avakian - Pasadena CA, US
Assignee:
Sierra Nevada Corporation - Sparks NV
International Classification:
H01Q 3/24
US Classification:
343876, 343700 MS
Abstract:
An electronically controlled monolithic array antenna includes a transmission line through which an electromagnetic signal may be propagated, and a metal antenna element defining an evanescent coupling edge located so as to permit evanescent coupling of the signal between the transmission line and the antenna element. The antenna element includes a conductive ground plate; an array of conductive edge elements defining the coupling edge, each of the edge elements being electrically connected to a control signal source, and each of the edge elements being electrically isolated from the ground plate by an insulative isolation gap; and a plurality of switches, each of which is selectively operable in response to the control signal to electrically connect selected edge elements to the ground plate across the insulative isolation gap so as to provide a selectively variable electromagnetic coupling geometry of the coupling edge.

Scanning Antenna With Beam-Forming Waveguide Structure

View page
US Patent:
7667660, Feb 23, 2010
Filed:
Mar 26, 2008
Appl. No.:
12/056132
Inventors:
Vladimir Manasson - Irvine CA, US
Vladimir I. Litvinov - Aliso Viejo CA, US
Lev Sadovnik - Irvine CA, US
Mark Aretskin - Irvine CA, US
Mikhail Felman - Tarzana CA, US
Aramais Avakian - Pasadena CA, US
Assignee:
Sierra Nevada Corporation - Sparks NV
International Classification:
H01Q 13/00
US Classification:
343785, 343781 R, 343781 P
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.

Monolithic Semiconductor Microwave Switch Array

US Patent:
7777286, Aug 17, 2010
Filed:
Nov 13, 2007
Appl. No.:
11/939385
Inventors:
Vladimir Manasson - Irvine CA, US
Vladimir I. Litvinov - Aliso Viejo CA, US
Lev Sadovnik - Irvine CA, US
Aramais Avakian - Pasadena CA, US
Assignee:
Sierra Nevada Corporation - Sparks NV
International Classification:
H01L 21/329
US Classification:
257428, 333103, 257E21352, 438128
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.

US Patent:
8059051, Nov 15, 2011
Filed:
Jul 7, 2008
Appl. No.:
12/168728

Vladimir Manasson - Irvine CA, US
Victor Khodos - Torrance CA, US
Lev Sadovnik - Irvine CA, US
Aramais Avakian - Pasadena CA, US

International Classification:
H01Q 13/00
US Classification:
343785, 343700 MS, 343772, 343776, 343853
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.
