Abstract
A phased array antenna is described that groups radiating elements into rows and columns. The radiating elements in a row are fed by a common phase shifted signal and the radiating elements in a column are fed by a common phase shifted signal. As such, each radiating element is fed by two different phase shifters. The overlapping groupings of rows and columns allows the antenna to be electronically steered by varying the phase shift applied to the rows and columns. The overlapped sub-arrays of the phased array antenna reduces the number of required phase shifters for the antenna array.
