  • Patent number: 10986636
    Abstract: A wireless communication system includes frequency reuse between terminals in common coverage regions using a multiple satellite architecture with spatial diversity. Different terminals may be associated with different ones of the satellites such that a common frequency can be reused by the different terminals. A gateway may communicate with a first satellite using a feeder beam having an overlapping geographic coverage region with a user beam used for communication between a set of user terminals and a second satellite. Spatial diversity is provided between the satellites, and the feeder beam and the user beam operate at common frequencies within the overlapping coverage region. In this manner, the bandwidth of both satellites at the common coverage region is used to increase the available capacity.

  • Publication number: 20030025646
    Abstract: The present invention is directed to, in a first aspect, an antenna array stimulation system. In one embodiment the system comprises an array of radiating elements, a conductive layer adjacent the array of radiating elements adapted to receive electrical energy from, or couple electrical energy to, the array, and at least one connection device adapted to couple the electrical energy between the conductive layer and a test unit, wherein antenna performance degradation due to potential losses in coupling the energy between the conductive layer and the test unit are minimized.
