Summary:A planar, low-profile, very wide frequency bandwidth, wide-scan, dual-linear or circular-polarized phased array antenna (90) using integrated stacked-disc radiator tiles (10). The stacked-disc radiator configuration comprises a lower active radiator (64) fed by a pair of probes (63) for each polarization state, and a parasitic radiator (66) separated from the active radiator by dielectric material (61). The stacked-disc radiator is integrated with its multi-layer feed circuits (41, 50) in a very compact package. The feed circuits include 90 DEG hybrid coupler circuits (32, 33) and 180 DEG hybrid coupler circuits (53) that couple dual linear or dual circular polarized energy to and from the disk radiators.
