Embodiment Construction

[0051] Embodiments of the present disclosure will be described below with reference to the drawings. In addition, deviations are allowed in directions such as parallel, right angle, horizontal, vertical, orthogonal, up and down, left and right, which do not impair the effect of the present invention. In addition, the X-axis direction, the Y-axis direction, and the Z-axis direction represent directions parallel to the X-axis, directions parallel to the Y-axis, and directions parallel to the Z-axis, respectively. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other. The XY plane, YZ plane, and ZX plane respectively represent a virtual plane parallel to the X-axis direction and the Y-axis direction, a virtual plane parallel to the Y-axis direction and the Z-axis direction, and a virtual plane parallel to the Z-axis direction and the X-axis direction.

Abstract

The present invention ensures the reception sensitivity in an arrangement region of an antenna conductor and an AM broadcast band region. A trunk door includes a resin outer plate having an opening formed therein, a resin inner plate, a metal reinforcing material disposed between the outer plate and the inner plate, and a rear window glass covering the opening. The rear window glass includes a first antenna conductor capable of receiving radio waves in a frequency band of AM broadcast waves, the first antenna conductor has a first power supply unit, and a first antenna element connected to thefirst power supply unit and having a total length of 100 mm-1800 mm. The first antenna element extends along a first outer edge of upper, lower, left, and right outer edges of the demister at an interval of 3 mm-60 mm, and is located at a distance of 10 mm or more from the reinforcing material, or located at the side where the reinforcing material is not present with respect to the first outer edge in a plan view of the rear window glass.

Description

technical field [0001] The present invention relates to tailgates and rear windows. Background technique [0002] The rear window of a vehicle is equipped with various functional components such as defoggers and antennas on the premise that the field of view can be ensured. However, in a vehicle (for example, a hatchback) with a relatively narrow size (area) of the rear window, it is difficult to secure a space for an antenna for an AM broadcast band region if a space for a defogger is secured. Therefore, in the arrangement of the antenna for the AM broadcast band region, it is necessary to study the relationship with the arrangement of the defogger. As an antenna for such an AM broadcast band area, an antenna provided on the rear window glass of a resin tailgate with a metal reinforcing material and provided along the four sides of the defogger, up, down, left, and right is disclosed. An antenna with conductors on at least three sides (for example, refer to Patent Documen...
