1. A phased array circuit comprising:
a first beam forming network;
a first dual-polarized radiating element;
a second dual-polarized radiating element;
a first polarization control circuit coupled to the first dual-polarized radiating element;
a second polarization control circuit coupled to the second dual-polarized radiating element;
a first phase shifter coupled between the first polarization control circuit and the first beam forming network for phase shifting a first composite signal communicated between the first polarization control circuit and the first beam forming network; and
a second phase shifter coupled between the second polarization control circuit and the first beam forming network for phase shifting a second composite signal communicated between the second polarization control circuit and the first beam forming network, wherein the first beam forming network is configured to convert between: (1) a first beam signal; and (2) the first composite signal and the second composite signal.
