This common aperture dual polarization antenna array (30) includes an antenna aperture (36) and a plurality of centered slot arrays (32) positioned within the antenna aperture (36). A plurality of notch dipole arrays (34) are positioned within the antenna aperture (36) and positioned substantially orthogonal to the plurality of centered slot arrays (32). A first feed guide (46) is coupled to the plurality of centered slot arrays (32) and a second feed guide (56) is coupled to the plurality of notch dipole arrays (34). | |
