Patent number: 11799196Abstract: An antenna apparatus has a sleeve antenna. The sleeve antenna has an internal conductive member, an external conductive member, an insulating member, and a mountain-shaped conductive member that is electrically connected to the external conductive member. The mountain-shaped conductive member expands radially from an upper edge towards a lower edge. The internal conductive member protrudes higher than the external conductive member above the upper edge of the mountain-shaped conductive member.Type: GrantFiled: November 18, 2021Date of Patent: October 24, 2023Assignee: Yokowo Co., Ltd.Inventors: Tomohiko Yamase, Satoshi Iwasaki, Kazuya Matsunaga

Patent number: 10476144Abstract: A vehicle includes a roof panel and a vehicle antenna device. The roof panel includes a roof portion and an antenna cover portion that protrudes from the roof portion and has an internal space. The vehicle antenna device includes a base portion and an upright portion that extends from the base portion into the internal space in the antenna cover portion. An outer imaginary plane is assumed to extend along a boundary line on a boundary portion between an outer surface of the roof portion and an outer surface of the antenna cover portion. In a state where the vehicle antenna device is mounted on the vehicle, at least part of the base portion is located below the outer imaginary plane.Type: GrantFiled: February 23, 2016Date of Patent: November 12, 2019Assignees: KABUSHIKI KAISHA TOYOTA JIDOSHOKKI, YOKOWO CO., LTD.Inventors: Yuichi Mizutani, Tomohiko Yamase, Seiji Go
