Methods and apparatus for dual polarized super-element phased array radiator

Methods and apparatus for a dual polarization super-element radiator assembly. In one embodiment, an assembly comprises a first waveguide, a series of slot couplers formed in the first waveguide, first and second conductive strips, a second waveguide adjacent to the first waveguide, a series of notches formed in a conductive material extending along or parallel to the longitudinal axis of the second waveguide, the notches having respective throats, a series of slots located proximate the notch throats, and a third conductive strip disposed over and aligned with the notches, wherein the slot couplers and the notches provide a dual polarization super-element radiator.
