    摘要: A reflector (8) for a reflector antenna is provided for producing a far field pattern with near-zero field strength at a predetermined position, the reflector having a surface comprising a stepped profile for generating the near-zero field strength. The stepped profile may comprise a radial step. The location of the near-zero field strength can be steered by moving the reflector only or by adjusting the amplitude and phase of an additional beam, produced by a further radiator (16), that covers substantially the same region as the main beam reflected by the reflector.

    摘要: A shared beamformer flexibly allocates beams among clusters of beams produced by phased array antenna apertures that are deployed on a satellite (or other type of platform). By sharing the beamformer among the beam clusters, if one beam cluster is not providing useful coverage, the beams may be reallocated to one or more other beam clusters that are providing useful coverage. To share the beamformer among the beam clusters, a selector network is used to select which particular beam cluster (or clusters) is used for producing one or more narrow beams that are constrained to the coverage area of the beam cluster (or clusters).

    摘要: An antenna has a 90-degree polarization separation between at least two antenna elements regardless of how a user adjusts the antenna, and yet enables the user to adjust the antenna for the best signal reception. The antenna has a pivotally adjustable structure that is configured to maintain the antenna elements at substantially a right angle with respect to each other, including a universal joint that enables the antenna to be rotated in mutually orthogonal planes. The user in one step can adjust the antenna for the best reception and simultaneously maintain optimum polarization separation between the main and the diversity antenna elements.

    摘要: A self-correcting mobile antenna control system and method. A method is provided for controlling the direction of an antenna mounted on a vehicle. The method includes determining a position decision based on a direction change signal output from a direction sensor, determining an energy decision based on a signal strength indicator, combining the position decision and the energy decision to produce an antenna control signal, and adjusting the antenna's direction based on the antenna control signal. The system also operates to periodically calibrate itself to offset any sensor errors so that intensive calibration procedures can be avoided.
