According to one embodiment of the invention, a method of increasing a phase resolution of an array antenna (10; 110; 210; 310), comprises providing an array antenna having a plurality of rows (70; 170) of antenna elements (60; 160; 260; 360), each antenna element (60; 160; 260; 360) having a first phase resolution; for at least one row (70; 170) of the array antenna (10; 110; 210; 310), positioning each of the antenna elements (60; 160; 260; 360) to one of first and second phases, the first and second phases separated by at least the first phase resolution; for the at least one row (70; 170) of the array antenna (10; 110; 210; 310), a number of antenna elements (60; 160; 260; 360) positioned to the first phase is the product of a number of antenna elements (60; 160; 260; 360) in the at least one row (70; 170) of the array antenna (10; 110; 210; 310) and a desired row phase angle divided by the first phase resolution; and for the at least one row of the array antenna (10; 110; 210; 310), a number of antenna elements (60; 160; 260; 360) positioned to the second phase is the number of elements (60; 160; 260; 360) in the at least one row (70; 170) of the array antenna (10; 110; 210; 310) minus the number of antenna elements (60; 160; 260; 360) in the at least one row (70; 170) positioned to the first phase.
