Device and method for reducing interference with adjacent satellites using a mechanically gimbaled asymmetrical-aperture antenna

An antenna for mounting on a mobile vehicle for communicating with a satellite, the antenna comprising:

• a radiating surface to produce a beam having an asymmetric beam pattern with a narrow-beamwidth direction and a wide-beamwidth direction, the radiating surface comprising a plurality of radiating elements;
• one or more control elements to adjust an offset angle of the beam from a perpendicular of the radiating surface in the narrow-beamwidth direction by adjusting a plurality of signals communicated with the plurality of radiating elements;
• an azimuth adjustment to rotate the radiating surface about a first axis;
• an elevation adjustment to rotate the radiating surface about a second axis;
• and
• control circuitry to provide first commands to the one or more control elements to adjust the offset angle of the beam, the control circuitry further to provide second commands to the azimuth adjustment and the elevation adjustment to control the azimuth adjustment and the elevation adjustment to point the beam in a direction toward the satellite, wherein the first and second commands are based at least in part on a location of the mobile vehicle.
