Abstract

An array antenna device (100) is provided with: a first layer (10) in which a plurality of antenna elements (11) are arranged in a grid shape; and a second layer (20) that overlaps the first layer (10). The second layer (20) has: an IF signal main line (21) and an LO signal main line (22) that extend in the orthogonal direction to each other; an IF signal branch line (23) and an LO signal branch line (24) that extend in the orthogonal direction of the IF signal main line (21) and the LO signal main line (22); and a plurality of mixers (29) that are arranged in the same grid shape as the plurality of antenna elements (11) at the intersections of the branch lines (23, 24), and electrically connected to the branch lines (23, 24) and the antenna elements (11). Phase shifters (25, 26, 27, 28) are provided between the connection points of the branch lines (23, 24) in the main lines (21, 22) and/or between the connection points of the mixers (29) in the branch lines (23, 24). The first layer (10) and the second layer (20) vertically overlap such that the arrangement region (110) of the plurality of antenna elements (11) in the first layer (10) and the arrangement region (290) of the plurality of mixers (29) in the second layer (20) overlap in a plan view.
