Abstract: Methods and apparatus for a radiator assembly having a feed circuit with an air interface to a quadridge feed structure to excite an antenna, such as a stacked patch antenna. Embodiments of the assembly can provide enhanced bandwidth, scan angle performance, and coincident phase centers for dual-linear polarizations.
