    Abstract: Wireless radio apparatuses for point-to-point or point-to-multipoint transmission/communication of high bandwidth signals having dual receivers and transmitters. Radio devices and systems may include a pair of reflectors separated by an isolation choke boundary. The device may be configured to operate in any appropriate band (e.g., a 5 GHz band, a 24 GHz band, etc.) and may simultaneously transmit and receive with minimal crosstalk. The isolation choke boundary may have ridges that extend between the first and second parabolic reflectors to a height that may be tuned to the band. The isolation choke boundary provides greater than 10 dB isolation between the first and the second parabolic reflectors may be in a fixed configuration relative to each other so that they are aligned to send/receive in parallel. The two reflectors may be formed of a single housing, with fixed parallel alignment.

  • Patent number: 8860626
    Abstract: A radome for covering an open end of a reflector dish of a reflector antenna has a generally planar portion of twin-wall extruded polymer material dimensioned to cover the open end of the reflector dish. A periphery of the planar portion is provided with a plurality of slits, the slits defining a plurality of tabs. The tabs are dimensioned for folding around a rim of the reflector dish. The tabs may be retained in the folded position by, for example, a band clamp or directly coupling a portion of the tabs to the planar portion.

  • Patent number: 8854275
    Abstract: An antenna apparatus includes an electrically conductive section having peripheral edges, an antenna element coupled to the electrically conductive section, which transmits or receives electromagnetic signals, and an electromagnetic absorbing carbon material component. The carbon material component is generally disposed adjacent to the electrically conductive section, and includes a border region extending beyond the peripheral edges of the electrically conductive section. The carbon material component can be constructed of a carbon fiber fabric in which the carbon fibers are arranged to increase the effective signal to noise ratio of the antenna apparatus and enhance antenna performance without increasing the baseline power consumption level. The carbon fibers can be coated with silicone to insulate them externally while enhancing their lengthwise conductivity.

  • Patent number: 8854271
    Abstract: This invention is directed toward a data signal receiving means including an antenna and a plurality of Low Noise Blocks (LNB's). A reflective filtering means is provided and located with respect to the LNBs and antenna such that data signals received at a first frequency or frequency range pass through the reflective filter means to a first LNB and data signals at second frequency or frequency range are deflected by the reflective filtering means and do not pass therethrough and pass to the second LNB. In this way a single antenna can be used to receive and process multiple data signals received at different frequencies or frequency ranges.

  • Patent number: 8810468
    Abstract: A beam-shaping element is provided to shape RF feed energy for reflector-based antennas. The RF beam-shaping element is located between the primary reflector and the antenna feed and configured to direct RF energy from the feed away from a blockage created by the feed itself towards unblocked regions of the primary reflector. The beam-shaping element allows for a simplified feed design. The feed may comprise one or more feed elements, each comprising a radiating element and a feed to the radiating element such as a cavity-backed slot radiator and stripline trace. In a monopulse tracking system, each quadrant may include only a single feed element. In common aperture systems, the RF beam-shaping element may be formed on only the rear surface of the secondary reflector that allows transmission at the predefined RF wavelength while reflecting energy of a second predetermined wavelength to another sensor.

    Abstract: In certain embodiments, a segmented reflector and an antenna having a segmented reflector are disclosed. In certain embodiments, the segments of the reflector are held in side-by-side relationship by the antenna transceiver. In certain other embodiments, the segments of the reflector are held in side-by-side relationship by magnets in each of the segments that are attracted to magnets in adjacent segments. In some embodiments, interengaging male and female detents are provided in the segment endwalls in order to resist shear forces once the segmented reflector is assembled. Other embodiments are also disclosed.

  • Publication number: 20140218256
    Abstract: An antenna device includes a reflector which forms an offset antenna with a portion of a rotational paraboloid being cut out, and a primary radiator which radiates a beam having an elliptical cone shape to an aperture plane of the reflector. A reflector contour of the aperture plane of the reflector is formed in an elliptical shape along an isolux line of an elliptical beam radiated from the primary radiator. Accordingly, a loss due to spillover of the reflector is compensated for in a space in which the reflector contour of the present embodiment protrudes from a general reflector contour having a virtual elliptical shape formed to be perpendicular to an axis of a beam incident on an aperture plane of the reflector. In a space in which the general reflector contour protrudes from the reflector contour of the present embodiment, degradation of illuminance efficiency of the reflector is compensated.
