Patent ID: 7250908

Claim:
A phased array flat panel antenna comprising: a plurality of M sets of radiating elements, wherein each of said M sets is spaced apart and aligned in a first direction; a plurality of N sets of radiating elements, wherein each of said N sets is spaced apart and aligned in a second direction that is in a substantially quadrature relationship with said first direction; a plurality M of phase shifters, each of said M phase shifters directly supplying signals of a near similar, but different, phase to at least one of said sets of N radiating elements; a plurality N of phase shifters, each of said N phase shifters directly supplying signals of a near similar, but different, phase to at least one of said sets of M radiating elements; and wherein each radiating element is concurrently fed by a first feedline and a second feedline in which the first feedline and the second feedline are independent of each other.
