PHASED ARRAY ANTENNA WITH REDUCED PHASE QUANTIZATION ERRORS

摘要

Docket R4069 PHASED ARRAY ANTENNA WITH EAO:lhw REDUCED PHASE QUANTIZATION ERRORS A phased array antenna includes a coupling network which is arranged to supply signals to pairs of elements located on opposite sides of the array center with a phase difference which is an odd-integral multiple of one-half the smallest phase step of the array phase shifters. This coupling network arrangement reduces antenna beam pointing errors which arise from a phase quantization of the array phase shifters.
