Systems and methods of controlling signal polarization for an antenna system are provided herein. The antenna system includes an ultra wide band or greater array of dual linear polarization elements. The antenna system also includes polarization synthesis networks. Each of the polarization synthesis networks is coupled to the first differential interface of the first element of a respective dual linear polarization element of the dual linear polarization elements and the second differential interface of the second element of the respective the dual linear polarization element of the dual orthogonal linear polarization elements. Each of the polarization synthesis networks has a flat response for phase shift and amplitude over the ultra wide bandwidth.
