[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flat antenna integrated with a vehicle warning light, which is a combination of a flat antenna and a high mount stop lamp, which constitutes a microstrip antenna suitable for the UHF band.

[0002]

[Prior Art]

 Conventionally, various antennas have been studied in various vehicles such as automobiles used in the UHF band, telephones for aircraft, and satellite communication fields. In particular, as an antenna used in a system that uses a GPS satellite signal to detect the position of an automobile, a planar antenna has been proposed in which an antenna conductor is formed on one surface of a resin or ceramic substrate and a ground conductor is formed on the other surface. There is. Further, in vehicles such as automobiles, a high mount stop lamp has been proposed in which a light-emitting body composed of a light source such as an LED is installed near a rear parcel shelf or a rear glass in a vehicle compartment for the purpose of ensuring safety such as collision prevention.

However, the planar antennas and high mount stop lamps that have been proposed so far are separately installed on the vehicle body inside or outside the vehicle compartment, so that the mounting productivity is poor and the interior of the vehicle interior is poor. It occupies the space and has a design problem.

[0004]

[Problems to be solved by the device]

 The present invention is intended to eliminate the above-mentioned drawbacks of the prior art, and newly provides a previously-known planar antenna integrated with a vehicle warning light.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and includes a dielectric substrate having at least one hole, an antenna conductor provided on at least a part of one surface of the dielectric substrate, and a dielectric substrate. A planar antenna integrated with a warning light for a vehicle, comprising a grounding conductor provided on at least a part of the surface, and a light source for emitting warning light disposed in the hole.

【Example】

 Hereinafter, embodiments will be described in detail with reference to the drawings. FIG. 1 is a front view of the planar antenna of the embodiment, and FIG. 2 is a sectional view taken along line AA of FIG. In FIGS. 1 and 2, 11 is a dielectric substrate and 12 is an antenna conductor. Reference numeral 13 is a power feeding portion, 14 is a ground conductor, and 15 is a light source including an LED.

As shown in FIGS. 1 and 2, the configuration of the planar antenna according to the embodiment is as follows. An antenna conductor 12 is formed on one surface of the dielectric substrate 11, and a ground conductor 14 is formed on the other surface. Further, the dielectric substrate 11 is provided with at least one hole. A light source 15 for emitting a warning light is arranged in this hole.

In the embodiment, the antenna conductor 12 is printed on one surface of the dielectric substrate 11 made of soda lime glass, and the ground conductor 14 is printed on the other surface of the dielectric substrate 11 in a grid pattern using an Ag-based thick film conductor. The feeding portion 13 is provided with a hole in the dielectric substrate 11, is sealed with a conductor, and is connected to an amplifier arranged on the surface of the ground conductor 14. This amplifier is not needed if the antenna conductor 12 is sufficiently sensitive.

An LED is used as the light source 15. Here, the line width of the lattice-shaped antenna conductor 12 is 2 mm and the line width of the ground conductor 14 is 3 mm, but the present invention is not limited to this. As the dielectric substrate 11, a fluororesin or a ceramic may be used instead of the glass plate. Further, when the tip of the light source 15 does not project from the surface of the antenna conductor 12 of the dielectric substrate 11, the dielectric substrate 11 can be directly bonded to the rear glass plate of a vehicle or the like.

[0010]

[Effects of the Invention] The present invention has a microstrip antenna and a high mount stop lamp integrated with each other to expand the space inside the vehicle interior. Also, by bonding the dielectric substrate to the rear glass plate, the installation becomes easy and the production is improved. It is possible to improve the sex.
