Abstract
A subscriber module of a fixed wireless access communication system comprises an offset Gregorian antenna arrangement, an array of antenna elements arranged as a feed, a beamforming network and a processor. The processor is configured to provide, to the beamformer, a pre-determined plurality of antenna weight vectors configured to form a plurality of beams, the orientations of the plurality of beams being arranged in a grid comprising a plurality of rows, each of the pre-determined plurality of antenna weight vectors being configured to form a respective beam from the primary reflector dish of the Gregorian antenna arrangement by forming a respective feed beam from the array of antenna elements. The relationship between the azimuth and elevation direction of each feed beam and the azimuth and elevation direction of the respective beam from the primary reflector dish is a non-linear function of azimuth and elevation.
