Abstract
A method and apparatus for forming satellite transmission beams are disclosed. A beamforming network in accordance with the present invention comprises an array of antennas and primary and secondary dividing networks. The array of antennas comprises at least a first subarray having a first number of elements and a second subarray having a second number of elements. The primary dividing network divides a beam signal into a plurality of panel signals, wherein a number of panel signals is substantially equal to a number of subarrays. The secondary dividing network divides a first panel signal into a first plurality of element signals substantially equal in number to the first number of elements and for dividing a second panel signal into a second plurality of element signals substantially equal in number to the second number of elements.
