  • Patent number: 9337544
    Abstract: A reflector support system is provided that includes a backing structure having a plurality of struts. The backing structure may have a plurality of hubs, each of the plurality of hubs may be configured to couple to two or more of the plurality of struts, each of the plurality of hubs may be configured to couple to another one of the plurality of hubs using one of the plurality of struts, each of the plurality of struts is configured to couple to at least two of the plurality of hubs. The backing structure may have a plurality of feet, each of the plurality of feet configured to couple to a corresponding one of the plurality of hubs, the plurality of feet are configured to couple to a reflector. In addition, a synthesis for mechanical adjustment of the reflector support system is provided.

  • Patent number: 8212734
    Abstract: An antenna system comprises a first reflector and a second reflector including one or more radiating elements disposed on a side of the second reflector facing the first reflector. The one or more radiating elements are configured to illuminate the first reflector. The antenna system further comprises a dual reflector feed configured to illuminate the second reflector. The antenna system may further include a beamforming network configured to feed the radiating elements, and to provide amplitude weighting and/or phase control to the antenna system.

  • Patent number: 7579995
    Abstract: An antenna system is provided. The antenna system comprises a first antenna with a first operating frequency and a second antenna with a second operating frequency. The second antenna has a first near field with a first near region in which the first antenna is disposed and a second near region. The second antenna has a first gain in the first near region which is lower than a second gain in the second near region. The first gain and the second gain are both at a same one of the first operating frequency and the second operating frequency.
