Patent ID: 7327313

Claim:
A method of increasing a phase resolution of an array antenna, the method comprising: providing an array antenna having a plurality of rows of antenna elements, each antenna element having a first phase resolution and emitting a signal; and for at least one row of the array antenna, manipulating the signal of each of the antenna elements to one of first and second phases, the first and second phases separated by at least the first phase resolution, wherein: for the at least one row of the array antenna, a number of antenna elements with signals manipulated to the first phase is the product of a number of antenna elements in the at least one row of the array antenna and a desired row phase angle divided by the first phase resolution, and for the at least one row of the array antenna, a number of antenna elements with signals manipulated to the second phase is the number of elements in the at least one row of the array antenna minus the number of antenna elements with signals manipulated to the first phase in the at least one row.
