Abstract
Wiring and a wiring path of a feed line for feeding power to a radiation element is simplified. An array antenna includes a first conductive pattern layer, first dielectric layer, conductive ground layer, second dielectric layer, second conductive pattern layer, third dielectric layer, and radiation element pattern layer that are layered in this order. The radiation element pattern layer includes radiation element pairs arranged in a two-dimensional array pattern. Each of the radiation element pairs includes a first radiation element and a second radiation element arranged side by side with an interval therebetween. The second conductive pattern layer includes branch feed lines arranged in a two-dimensional array pattern to correspond to the radiation element pairs, respectively. The first conductive pattern layer includes feed lines corresponding to the branch feed lines, respectively.
