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.

摘要： Provided is an antenna device which is less prone to deterioration in radiation characteristics and which can be mounted in a small space. A second antenna element (13) includes a first portion (13a) and a second portion (13b). A first antenna element (12) is disposed on a first plane (P1), the first portion (13a) is disposed on a second plane (P2), and the second portion (13b) is disposed on a third plane (P3). When viewed in a direction orthogonal to the first plane (P1), the second portion (13b) does not overlap the first antenna element (12) except at an end region (13c).
