A phased array antenna having a plurality of independent antenna modules which are arranged in a manner to significantly improve cross polarization isolation of the antenna. The antenna modules are arranged in rows and columns to form a grid arrangement. Each antenna module has a pair of radiating elements, and each module is rotated 90° from its adjacent antenna modules in each column. In this manner, the worst case cross polarization isolation performance of each module is not summed together at the same azimuth scan angle as every other module but rather is broken up over the entire azimuth scan angle.
