Abstract

PURPOSE:To prevent the external appearance of a car body itself from being lost or to obstruct the view while keeping a function receiving a broadcast radio wave by providing an antenna pattern to the circumferential ridge of a window pane for a vehicle covered by a car body. CONSTITUTION:The circumferential ridge of a quarter glass 1 is covered by a car body 5 and an antenna pattern 2A of a desired shape made of a proper material is adhered to the circumferential ridge. The end of a lead wire 4A is connected to a proper position of the antenna pattern 2A and the proper position of the car body 5 and a reception signal is sent to a receiver in the car body. The antenna pattern 2A is provided to the circumferential ridge of the window pane 1 for the car body covered by the car body 5. Thus, the possibility of the obstructed view or the external appearance of the car body itself is precluded and excellent reception of a broadcast radio wave is attained.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a vehicle antenna device.
The present invention relates to a vehicle antenna device that can satisfactorily receive various types of broadcast radio waves such as FM, Vl(F, and UHF').

[Prior Art] FIG. 2 is a schematic configuration diagram showing a conventional vehicle antenna device. In this figure 2, the quarter glass (1)
is provided at a suitable location on the vehicle body (5), and a conductor H (2) of a desired shape made of a suitable conductive material is attached to the quarter
A slit (3) of a predetermined width is provided between the conductor film (2) and the vehicle body (5). A coaxial line (4) is connected to a suitable location on the conductor film (2), and the received signal is transmitted to a receiving device (not shown) in the vehicle.

In the conventional vehicle antenna device described above, FM
, VHF, UHF, etc., by the potential difference generated on both sides of the pickpocket 71-(3) provided between the conductor film (2) on the quarter glass (1) and the vehicle body (5). The signal is received as a signal and transmitted to a receiving IU in the vehicle via a coaxial line (4) connected to a conductive film (2).

Although this conventional vehicle antenna device does not pose any particular problem in receiving broadcast radio waves, it is an eyesore because the conductor film (2) is provided on the quarter glass (1) in a position that can be seen from the outside. There was a risk that the vehicle would become damaged or the beauty of the vehicle itself would be damaged.

[Problems to be Solved by the Invention] The above-mentioned conventional vehicle antenna device has a conductor film provided in a position visible from the outside through the quarter glass, so it is particularly difficult to receive broadcast radio waves. Although this does not cause any problem, there is a problem that it may become an eyesore or spoil the beauty of the vehicle itself.

This invention was made to solve the above-mentioned problems, and the window glass part of the vehicle is no longer visible from the outside, and while retaining the function of receiving broadcast radio waves, it is no longer an eyesore. To obtain an antenna device for a vehicle that has no fear of causing damage to the vehicle or spoiling the beauty of the vehicle itself.

[Means for Solving the Problems] A vehicle antenna device according to the present invention includes an antenna pattern provided on the peripheral edge of a vehicle window glass covered by a vehicle body.

[For f-ya] According to the present invention, an antenna installed in a part of the window glass of a vehicle that cannot be seen from the outside is used in a manner that does not cause an eyesore or impair the beauty of the vehicle itself. Good reception of broadcast waves is achieved.

[Example] Next, the present invention will be described based on an example shown in the accompanying drawings.

FIG. 1 is a schematic configuration diagram showing a vehicle ambusher device which is an embodiment of the present invention. In this figure, a quarter glass (1) is provided in place on a vehicle body (5). (1^) is an end of the quarter glass (1), and the peripheral edge of the quarter glass (1) including this end (1^) is covered by the vehicle body (5). An antenna pattern (2^) of a desired shape made of a suitable material is attached to this peripheral edge.

In addition, lead wires (the ends of four stations are connected to appropriate places on the antenna pattern (2^) and on the vehicle body (5), so as to transmit the received signal to a receiving device (not shown) in the vehicle. It is being done.

” In the vehicle antenna device of the embodiment, FM,
Various broadcast radio waves such as VITF and UHF are transmitted to the vehicle body (
5), and is connected to the vehicle body (5) and antenna pattern (2^). Thus, according to the above embodiment, the antenna pattern is placed on the periphery of the quarter glass that is not visible from the outside. Since it is provided, there is no fear that it will become an eyesore or spoil the beauty of the vehicle itself, and the desired broadcast waves can be received well. In the above embodiment, the antenna pattern is attached to the periphery of the quarter glass; however, the antenna pattern is not limited to this, and may be attached to the periphery of the windshield, rear glass, etc. Fortunately, the same effects as in the above embodiment can be obtained also by this method.

[Effects of the Invention] As explained above, the vehicle antenna device according to the present invention is configured such that the antenna pattern is not provided on the peripheral edge of the vehicle window glass covered by the vehicle body,
By using an antenna installed in a part of the vehicle's window glass that cannot be seen from the outside, it is possible to receive broadcast waves in a manner that does not obstruct the eyes or spoil the beauty of the vehicle itself. The effect is produced.
