Pagination or Media Count:
A phased array antenna is disclosed including a central reference element. This is surrounded by a plurality of sub-elements which form the adaptive elements of the array and have no feed networks. Each adaptive element is essentially an L stub, with the adaptive elements oriented such that the L top loading is circumferential around the reference element. The plurality of adaptive elements, all with different orientations of the linear top loading allows the complex weights and adaptive nulling algorithm to generate any required polarization, and form an adaptive null to any arbitrary polarized interfering signal as required. Keywords Position finding, and Global positioning system.
