Abstract
An apparatus, system, and method for a receive function in a phased array including an M by N array of antenna elements, where M and N are the number of rows and columns, respectively, in the array of antenna elements. Each antenna element is provided with a combiner. The phased array apparatus and system includes M row beam-formers plus N column beam-formers. The row beam-formers supply a progressively phase-shifted carrier signal to the combiners where the signal received by the corresponding antenna element is combined with a phase-shifted carrier signal. The outputs of the combiners in each column of antenna elements is sent to a corresponding column beam-former. The outputs of the column beam-formers are combined to recover the signal that is desired to be received.
