    摘要: A very wide-band or dual-band phased array antenna using stacked-disc radiators on stacked-dielectric cylindrical posts to form radiator elements. Each radiator element includes a ground plane, a lower dielectric cylindrical post of a high dielectric material adjacent the ground plane, a lower thin conductive radiator disc formed on the upper surface of the lower dielectric post, an upper dielectric cylindrical post of a low dielectric material disposed on top of the lower post and lower radiator disc, and an upper thin radiator disc or annular ring formed on the upper surface of the upper post. The first radiator disc is excited by two pairs of probes arranged in orthogonal locations. Each pair of probes can be fed by coaxial cables with 180 degree phase reversal. The second radiator disc or annular ring is a parasitic radiator without feeding probes. Depending on the feed arrangement, the radiator elements can achieve single-linear polarization, dual-linear polarization or circular polarization.
