A dual polarized array antenna is disclosed. The array antenna includes a plurality of electrically conductive elements or posts, arranged in rows and columns. Multiple parallel slots are formed that intersect different rows and columns of electrically conductive elements. The slots receive feed elements that include a linear array of feed points. The feed points within each linear array alternate between a feed point associated with a first polarization and a feed point associated with a second polarization.

Dual-polarized array antenna

A dual-polarized antenna array is disclosed. The antenna array includes a plurality of self supporting, electrically conductive members. Tapered elements of neighboring electrically conductive members define tapered slots that form part of radiating structures. The radiating structures additionally include a slot line in communication with the tapered slot. A back cavity can be included as part of a BALUN structure that is integral to an electrically conductive member.
