A dual-polarized ultra-wideband array prototype operating from 2 to 8 GHz is designed, manufactured, and tested. The array consists of 8 × 16 connected slot elements per polarization, with artificial dielectric layers placed above the slots. The design exploits a feed concept based on parallel plate waveguides, with the goal of improving the manufacturability of the printed circuit board realizing the array. One-to-eight corporate feeding networks are also designed to reduce the number of coaxial connectors. Measured results of the matching and radiation performance are shown to be in good agreement with simulated predictions.
