20120194399 | Surface scattering antennas - Surface scattering antennas provide adjustable radiation fields by adjustably coupling scattering elements along a wave-propagating structure. In some approaches, the scattering elements are complementary metamaterial elements. In some approaches, the scattering elements are made adjustable by disposing an electrically adjustable material, such as a liquid crystal, in proximity to the scattering elements. Methods and systems provide control and adjustment of surface scattering antennas for various applications. | 08-02-2012 |
20140154895 | HIGH DENSITY HIGH SPEED DATA COMMUNICATIONS CONNECTOR - An outlet that includes first and second substrates, and a plurality of electrical contacts. The first substrate includes an electrical circuit adjacent to and spaced apart from a first ground plane. Each of the electrical contacts is connected to the circuit. The second substrate includes a second ground plane electrically connected to the first ground plane. The circuit is spaced apart from the second ground plane. The electrical contacts are positioned adjacent to the first and second substrates. Together the first and second ground planes may form a localized, electrically floating, isolated ground plane. The outlet may be connected to a cable and/or configured to be mounted to a panel for use with a rack. The outlet may be implemented as a Category 7A and/or Next Generation type outlet having an overall height that allows two rows of twenty-four like outlets to be mounted within one rack unit (“1RU”). | 06-05-2014 |

20150222014 | WAVEGUIDE FEED STRUCTURES FOR RECONFIGURABLE ANTENNA - A reconfigurable holographic antenna includes a waveguide and a metamaterial layer. The metamaterial layer includes an array of tunable slots. In one embodiment, the array of tunable slots is configurable to generate holographic diffraction pattern(s) to steer received communication signals. | 08-06-2015 |
20150222021 | RIDGED WAVEGUIDE FEED STRUCTURES FOR RECONFIGURABLE ANTENNA - A reconfigurable holographic antenna includes a metamaterial layer and a waveguide with at least one ridge. The metamaterial layer includes an array of tunable slots configurable to form holographic diffraction patterns. A reactance of each tunable slot in the array of tunable slots is individually tunable. The at least one ridge influences coupling between tunable slots in the array of tunable slots. The holographic diffraction patterns formed by the array of tunable slots generate a desired antenna wave in response to a received feed wave. | 08-06-2015 |
