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