  • Patent number: 10658756
    Abstract: An earth coverage antenna system includes a reflector, a feed horn and a strut. The reflector has a circularly symmetric reflector surface. The feed horn is positioned on the symmetry axis of the reflector and is attached to the strut. The feed horn transmits RF microwave energy toward the reflector surface. The antenna system further includes two cables that prevent side-ways movement of the strut. The antenna system further includes a lens assembly that directs microwave energy away from the central region of the reflector. The antenna system further includes a microwave energy scattering device disposed at the center of the reflector to scatter microwave energy away from the feed horn. The reflector surface is defined by a perturbed parabolic geometrical shape that is swept around the symmetry axis. The reflector reflects most microwave energy towards the earth's horizon, but diverts enough microwave energy towards the regions closer to nadir so as to maintain an isoflux of energy on the earth's surface.

    Abstract: A steerable antenna architecture, or configuration, for optimal steering of transmitting and/or receiving beam over wide scan angles, is capable of steering the beam on a full hemisphere (2? steradians), with no singularity or key-hole within a coverage area and with only one RF rotary joint. The architecture includes a dual-reflector assembly defining an antenna focal point located close to a main reflector surface and a signal feed chain having a signal source located adjacent to the antenna focal point and defining a feed axis substantially pointing towards a sub-reflector intersection point. A first actuator rotates the feed chain and the dual-reflector assembly about a first rotation axis generally perpendicular to the feed axis and not intersecting with the coverage area. A second actuator rotates one of the main reflector and the dual-reflector assembly about a second rotation axis aligned with the feed axis.

  • Patent number: 9093737
    Abstract: An assembly includes a self-contained, adjustable shrouding for a MIMO or SISO, or combination thereof, retransmission system enclosure. The enclosure ensures proper coverage areas of small to large facilities. The proper coverage is achieved through cake layer pie designs that previously often resulted in capacity and sector overlay issues. The antenna enclosure has a directional nature that allows for dividing stadiums, arenas, tracks, (or other large groups) into manageable smaller coverage areas through controlled directional zoning.

  • Publication number: 20150097743
    Abstract: System for positioning a reflector includes a base (112), yoke (104) and a reflector in the form of a lens mirror assembly (10). A motor (120) is mounted and remains substantially stationary with respect to rotation about a first axis while the yoke rotates about the first axis. A connecting rod (152) actuated for movement by the motor is mechanically coupled to the reflector so that movement of the connecting rod in relation to the yoke imparts rotation to the reflector about the second axis when the reflector is supported by the yoke. A mechanical drive system couples an output shaft of the motor to the connecting rod. The mechanical drive system is arranged so that it varies an angular position of the reflector at a rate which is linearly related to the rotation of the output shaft.

  • Publication number: 20140218248
    Abstract: Devices and systems, and methods of using them, for point-to-point transmission/communication of high bandwidth signals. Radio devices and systems may include a pair of reflectors (e.g., parabolic reflectors) that are adjacent to each other and configured so that one of the reflectors is dedicated for sending/transmitting information, and the adjacent reflector is dedicated for receiving information. Both reflectors may be in a fixed configuration relative to each other so that they are aligned to send/receive in parallel. In many variations the two reflectors are formed of a single housing, so that the parallel alignment is fixed, and reflectors cannot lose alignment. The device/systems may be configured to allow switching between duplexing modes. These devices/systems may be configured as wide bandwidth zero intermediate frequency radios including alignment modules for automatic alignment of in-phase and quadrature components of transmitted signals.

  • Patent number: 8797221
    Abstract: A reconfigurable antenna that utilizes liquid metal to achieve dynamic antenna performance is disclosed. The reconfigurable antenna may utilize one or more liquid metal sections that can be variably displaced. Utilizing liquid metal may reduce certain undesirable effects associated with more conventional mechanical reconfigurable antennas including mechanical failure due to material fatigue, creep, and/or wear. Precise microfluidic techniques may be utilized in the design of a reconfigurable antenna that utilizes liquid metal. The reconfigurable antenna may utilize a circular Yagi-Uda array design and include movable parasitic director and reflector elements implemented using liquid metal (e.g., mercury (Hg)). The parasitic elements may be placed and rotated in a circular microfluidic channel around a driven antenna element utilizing a flow generated and controlled by a piezoelectric micropump.

  • Patent number: 8789116
    Abstract: The satellite television antenna device receives a set of desired satellite identifications (IDs) from a set top box (STB). The antenna device scans the sky and locks onto a satellite candidate by measuring microwave radiation. The antenna acquires identification of the satellite candidate from a set top box (STB), if ID is possible. Then, if the candidate was identifiable, the antenna system compares the candidate's ID to the set of desired satellite IDs. If the candidate ID is a member of the set, then the satellite antenna's dish orientation is stored in memory. The antenna then attempts to acquire the remaining members of the set of desired satellite IDs until all members are acquired or no further candidates remain. If the candidate is not identifiable, or not a member of the set, then the antenna proceeds to the next satellite candidate.
