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.

Car and car antenna device

An antenna unit includes a base having a base-side fitting portion, antenna elements disposed on the base, an inner case fixed to the base and covering the antenna elements, and an outer case mounted on the base covering the inner case. The outer casehas an outer-case-side fitting portion fitted to the base-side fitting portion.

Antenna unit

A vehicle antenna assembly includes an element coil, a holder, and a retainer. The element coil can have a polygonal configuration in a cross-section taken normal to a coil access. The holder can include rails. The retainer can engage the rails and apply a compressive load on the element coil to fix the element coil with respect to the holder. A method for holding an antenna element is also disclosed.

Vehicle antenna assembly

A core member includes a cylindrical body. An antenna element is disposed on an outer peripheral face of the cylindrical body. A first engagement member is provided on the outer peripheral face of the cylindrical body. A cap member includes a peripheral wall fitted over the core member so as to cover the antenna element. A second engagement member is provided on an inner peripheral face of the peripheral wall to engage with the first engagement member. A restraining member is brought into contact with an outer peripheral face of the peripheral wall of the cap member to prevent the peripheral wall being deformed outward. The restraining member is opposed to at least a position where the second engagement member is provided.

Antenna structure

An insulative member is formed with a hole. An antenna element is provided as a conductive foil adhered onto the insulative member and having a contact section opposing to the hole. A conductive member is fitted into the hole through the contact section of the antenna element, such that a part of the contact section is clamped between an outer face of the conductive member and an inner face of the hole.
