Abstract: An antenna includes a dielectric layer, a conductive ground layer formed on a first main surface of the dielectric layer, and radiation elements formed on a second main surface of the dielectric layer and are conductive. The first radiation element includes a first non-uniform width part that has a width in a direction parallel to a first side in a linear shape opposed to a first vertex, and the width of the first non-uniform width part gradually decreases in a direction from the first side to the first vertex. The second radiation element includes a second non-uniform width part that has a width in a direction parallel to a second side in a linear shape opposed to a second vertex, and the width of the second non-uniform width part gradually decreases in a direction from the second side to the second vertex.

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.
