Patent number: 11462825Abstract: 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.Type: GrantFiled: March 25, 2019Date of Patent: October 4, 2022Assignee: FUJIKURA LTD.Inventors: Kaushal Shailendra, Ning Guan

Patent number: 11387561Abstract: A dielectric loss when a signal wave is transmitted between a feed line and an antenna element via a slot is reduced. An antenna 21 includes: a dielectric substrate 28 including a recess 28b; a conductive ground layer 27 that is bonded to the dielectric substrate 28 to cover the recess 28b, and includes slots 27a-27d arranged on an inner side relative to the recess 28b; a dielectric layer 26 bonded to the conductive ground layer 27 on a side opposite to the dielectric substrate 28 relative to the conductive ground layer 27; antenna elements 29a-29d formed on a bottom 28d of the recess 28b at positions facing the slots 27a-27d; and a feed line 24a that is formed on a side opposite to the conductive ground layer 27 relative to the dielectric layer 26, and is to be electromagnetically coupled to the antenna elements 29a-29d via the slots 27a-27d.Type: GrantFiled: March 25, 2019Date of Patent: July 12, 2022Assignee: FUJIKURA LTD.Inventors: Kaushal Shailendra, Ning Guan

Patent number: 11342676Abstract: To improve a gain of an antenna. An antenna 1 includes a dielectric layer 6, a conductive ground layer 7 bonded to the layer 6 and including active slots 7c-7f aligned at regular intervals, aligned active elements 9c-9f formed facing the active slots 7c-7f, respectively, first passive elements 9b, 9a aligned with and extending from one end of a row of the active elements 9c-9f, second passive elements 9g, 9h aligned with and extending from the other end of the row, a feed line 4a formed on a side opposite to the layer 7 with respect to the layer 6, to be electromagnetically coupled to the active elements 9c-9f via the active slots 7c-7f. The second passive elements 9g, 9h are arranged in line symmetry with the first passive elements 9b, 9a with respect to a line 9z passing through the center of the row and perpendicular to the row.Type: GrantFiled: March 25, 2019Date of Patent: May 24, 2022Assignee: FUJIKURA LTD.Inventors: Kaushal Shailendra, Ning Guan
