Abstract
An antenna device includes a dual polarized quad-ridge antenna horn having an electrically conductive conduit with first and second opposite ends along a horn axis. Four electrically conductive ridges are carried on an inner side of the electrically conductive conduit. A printed wiring board including a dielectric substrate is connected across the first end of the dual polarized quad-ridge antenna horn and transversely to the horn axis. Furthermore, an electrically conductive pattern is formed on the dielectric substrate and defines feed elements for the dual polarized quad-ridge antenna horn.
