To widen a range of an angle in which the directivity of an antenna is controllable to be high. An antenna includes a sheet-shaped laminated body that includes a conductive pattern layer, a first dielectric layer, a conductive ground layer, and an antenna pattern layer, the antenna pattern layer including element rows arranged in parallel, the element rows each including even-numbered radiation elements that are connected in series and linearly aligned at an interval in a direction orthogonal to a parallel alignment direction of the element rows, the conductive pattern layer including feed lines for feeding power to the center of each or the element rows, the element rows being divided into groups using a bending line as a boundary, by bending the laminated body along the bending line.

Antenna

A dielectric loss when a signal wave is transmitted between a feed line and an antenna element via a slot is reduced. An antennaincludes: a dielectric substrateincluding a recess; a conductive ground layerthat is bonded to the dielectric substrateto cover the recess, and includes slots-arranged on an inner side relative to the recess; a dielectric layerbonded to the conductive ground layeron a side opposite to the dielectric substraterelative to the conductive ground layer; antenna elements-formed on a bottomof the recessat positions facing the slots-; and a feed linethat is formed on a side opposite to the conductive ground layerrelative to the dielectric layer, and is to be electromagnetically coupled to the antenna elements-via the slots-

To improve a gain of an antenna. An antennaincludes a dielectric layer, a conductive ground layerbonded to the layerand including active slots-aligned at regular intervals, aligned active elements-formed facing the active slots-, respectively, first passive elementsaligned with and extending from one end of a row of the active elements-, second passive elementsaligned with and extending from the other end of the row, a feed lineformed on a side opposite to the layerwith respect to the layer, to be electromagnetically coupled to the active elements-via the active slots-. The second passive elementsare arranged in line symmetry with the first passive elementswith respect to a linepassing through the center of the row and perpendicular to the row.
