Architectures and Methods for Novel Antenna Radiation Optimization via Feed Repositioning

Novel beam shaping techniques for satellite antennas featuring transmission and reception radiation patterns via element re-positioning comprising:

• a plurality of antenna elements forming an a satellite antenna array,
• a plurality of beam forming networks to produce both optimized transmit and received radiation patterns by repositioning said array elements, and
• a transmitting and/or receiving beam-forming architecture of said array antennas which alters element positions and spacing at least in one dimension as parameters to shape said radiation patterns of said array antennas, when all element weights are fixed and may be identical.

A novel satellite ground terminal featuring prescribed radiation patterns with a single directional beam for both reception and transmission functions by optimizing array element positions comprising:

• a plurality of antenna elements,
• a plurality of beam forming networks with fixed element weightings, and
• a transmit and/or receiving beam beam-forming method based on at least one-dimensional array element positioning of the ground array antennas to achieve directional beam peak and nulls for both transmitting and receiving functions.
