Dual-polarized array antenna

摘要

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.

1. An antenna, comprising:
a plurality of electrically conductive posts, wherein the electrically conductive posts are arranged in rows and columns; a plurality of feed elements,
wherein the feed elements are arranged along parallel lines,wherein at least some of the feed elements intersect a plurality of rows and a plurality of columns of the plurality of electrically conductive posts,wherein a first feed element in the plurality of feed elements includes a plurality of feed points,wherein each feed point in the plurality of feed points of the first feed element at least one of occupies or is adjacent a gap between two adjacent electrically conductive posts,wherein feed points included in a first subset of the plurality of feed points of the first feed elements are interconnected to a first feed network,wherein feed points included in a second subset of the plurality of feed points of the first feed element are interconnected to a second feed network, andwherein the feed points included in the first subset of the plurality of feed points of the first feed element alternate with feed points included in the second subset of the plurality of feed points of the first feed element.
