SHADE BAND ANTENNA SET IN A VEHICLE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shade band antenna, and more particularly, to a shade band antenna that forms a radiator in a shade band to block sunlight and also acts as an antenna.

Since there are many communication devices such as radio, DMB, navigation, etc. in a vehicle, installation of antennas for the communication devices is essential. Therefore, antennas are installed inside and outside the vehicle.

An internal antenna may be a sticker film antenna or a glass antenna installed in a window of a vehicle, and an external antenna may be a shark antenna.

In recent years, the number of communication devices installed in a vehicle is rapidly increasing, so more antennas are required, but there are many restrictions due to the limitation of the installation space. Particularly, in order to realize low frequency bands such as AM / FM bands, the radiator should have a sufficient length, but there are practically no methods to secure them due to the limitation of vehicle space. Therefore, when providing an actual AM service, there is often a problem that the AM band is not sufficiently satisfied in a foreign country.

Therefore, there is a need to utilize existing devices installed in a vehicle in order to increase space utilization, and in particular, a method capable of sufficiently securing the length of a radiator is required.

SUMMARY OF THE INVENTION An object of the present invention is to provide an antenna, preferably a shade band antenna, which can sufficiently secure the length of a radiator to increase space utilization of a vehicle and to implement a low frequency band.

In order to achieve the above object, a shade band antenna installed in a vehicle according to an embodiment of the present invention comprises a first radiator; And a plurality of shade members arranged to intersect with the first radiator.

According to another embodiment of the present invention, a shade band antenna installed in a vehicle includes: first shade members arranged on a window of the vehicle; Second shade members formed to intersect the first shade members; And a radiator formed outside the region where the first shade members and the second shade members are formed.

Shade band antenna according to another embodiment of the present invention is a substrate; A first radiator formed on the substrate; And a plurality of shade members arranged on the substrate to intersect with the first radiator.

Shade band antenna according to another embodiment of the present invention is a substrate; First shade members arranged on the substrate; Second shade members formed to intersect the first shade members; And a radiator formed outside the region where the first shade members and the second shade members are formed.

According to another embodiment of the present invention, a shade band antenna may include a first substrate; A first radiator arranged over the first substrate; A second substrate arranged vertically in parallel with the first substrate; And shade members arranged on the second substrate. Here, the first radiator and the shade members are arranged to intersect.

According to another embodiment of the present invention, a shade band antenna may include a first substrate; A first radiator arranged over the first substrate; A second substrate arranged vertically in parallel with the first substrate; And a second radiator arranged over the second substrate. Here, the first radiator and the second radiator are arranged to intersect.

Since the shade band antenna according to the present invention is formed in the shade band existing in the vehicle, the shade band antenna may function as an antenna while increasing the space utilization of the vehicle.

In addition, since the radiator and the shade members of the shade band antenna form a mesh structure, for example, the shade band antenna may serve as an existing shade band that blocks sunlight.

In addition, since the shade band antenna may have two or more radiators, the shade band antenna itself may implement a multi-band.

In addition, since the shade band antenna may not be directly formed on the window of the vehicle but formed as a separate element and then attached to the window as an after-sales service, the utilization of the shade band antenna may be increased.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a shade band antenna according to an embodiment of the present invention.

Referring to FIG. 1, the shade band antenna according to the present embodiment is an antenna implemented in a shade band formed on the front windshield 100 of the vehicle, and the first shade band antenna 104a formed on the windshield 100. And / or a second shade band antenna 104b.

The first shade band antenna 104a is formed at the upper end of the window 100 to operate as an antenna that implements a specific frequency band while blocking direct sunlight from the sun.

The second shade band antenna 104b is formed at the upper end of the glass window 100 to block sunlight and cover the entire room mirror 102 so that the room mirror 102 is not visible from the outside, and implements a specific frequency band.

That is, the shade band antenna 104a or 104b operates not only as a general shade band installed in a vehicle (sunlight blocking) but also as an antenna. To this end, the shade band antenna 104a or 104b includes a corresponding radiator.

Hereinafter, various structures of the shade band antenna 104 of the present embodiment will be described with reference to the accompanying drawings. However, for convenience of description, only the second shade band antenna 104b will be considered.

2 is a diagram illustrating a structure of a shade band antenna according to a first embodiment of the present invention.

Referring to FIG. 2 (A), the shade band antenna 104 of the present embodiment is formed on the outer surface or the inner surface of the window 100, the radiator 200, the shade members 202 and the feed point 204 ).

According to an embodiment of the present invention, the shade band antenna 104 may be formed on the glass window 100 as shown in FIG. 2 (B) through a pad printing or silk screen printing method using a pad as a printing medium. Can be. When the shade band antenna 104 is implemented through the printing method as described above, since the shade band antenna 104 may be implemented through one printing process, the process may be simplified.

The radiator 200 may be made of copper as a conductor, and may be implemented as a meander type, as shown in FIG. Of course, the radiator 200 structure is not limited to the meander type.

The shade members 202 are formed to intersect the radiator 200 as a non-conductor, and are preferably formed to have a mesh structure.

That is, since the radiator 200 and the shade members 202 form a mesh structure, direct radiation may be blocked as in a general shade band. In addition, since the shaded band antenna 104 includes the radiator 200, the radiator 200 may output a radiation pattern of a specific frequency band when feeding the radiator 200 through the feed point 204. For example, the shade band antenna 104 may implement a TDMB band, an AM band, or an FM band. In particular, since the shade band antenna 104 of the present embodiment can fully utilize the space of the shade band, the radiator 200 can be implemented with a sufficient length in the shade band. Accordingly, the shade band antenna 104 may implement the AM / FM band, which is a low frequency band, better than an antenna installed in a conventional vehicle.

In short, the shade band antenna 104 of this embodiment not only functions as a shade band but also functions as an antenna. Here, the radiator 200 and the shade members 202 included in the shade band antenna 104 may form a dense mesh structure to effectively block direct sunlight. Of course, the shade band antenna 104 may be variously modified as long as it can block sunlight without being limited to the mesh structure, and the radiator 200 may also be variously modified without being limited to the meander type.

Although not described above, an internal conductor of a cable extending from the interior of the vehicle may be electrically connected to the feed point 204, and thus power is supplied to the radiator 200 through the cable. In particular, in recent years, a high-pass or the like is attached to the room mirror 102 so that a specific cable is provided to the room mirror 102, so that the power supply can be implemented using the cable.

In addition, although only the structure of the second shade band antenna 104b is shown above, the first shade band antenna 104 may be similarly implemented.

In addition, although the radiator 200 and the shade members 202 are illustrated as being directly formed on the glass window 100 by, for example, a printing method, the radiator 200 and the shade members 202 may be formed in the glass window ( 100) or may be arranged on a particular substrate or film formed thereon. Of course, in this case, the shade band antenna 104 may be previously mounted in the vehicle, or may be separately attached after the shipment as an after-sales service.

3 is a diagram illustrating a shade band antenna according to a second exemplary embodiment of the present invention.

Referring to FIG. 3A, the shade band antenna of the present embodiment includes a first radiator 300, a second radiator 302, and shade members 304.

The second radiator 302 may be arranged along the first radiator 300, and the radiators 300 and 302 may form a mesh structure with the shade members 304.

The first radiator 300 is fed through the first feed point 306, and the second radiator 302 is fed through the second feed point 308. Here, separate cables may be connected to the feed points 306 and 308, respectively. Of course, one cable may be fed to the first radiator 300 only through the first feed point 306, for example, and the second radiator 302 may be implemented to be fed in a coupling manner from the first radiator 300. It may be.

Referring to FIG. 3B, the shade band antenna of the present embodiment includes a first radiator 310, a second radiator 312, and shade members 314.

The second radiator 312 may be arranged in parallel with the first radiator 310 while being spaced apart from the first radiator 310 by a predetermined distance. Of course, the radiators 310 and 312 may form a mesh structure with the shade members 314.

In short, the shade band antenna of the present embodiment may include two or more radiators. Here, the radiators implement different frequency bands, that is, the shade band antenna may implement a multi-band by itself. Of course, since the radiators and the shade members form a mesh structure, they may also serve as shade bands.

In the above, although the structure of the radiators are two examples, the structure of the radiators may be variously modified without being limited to the above structure.

4 is a diagram illustrating a structure of a shade band antenna according to a third embodiment of the present invention.

Referring to FIG. 4, the shade band antenna of the present embodiment includes first shade members 400, second shade members 402, a radiator 404, and a feed point 406.

The first shade members 400 and the second shade members 402 form a mesh structure to block sunlight.

The radiator 404 is arranged outside the region where the shade members 400 and 402 are formed, ie electrically separated from the shade members 400 and 402. Of course, a particular cable is electrically connected to feed point 406, and power supplied from the cable is provided to radiator 404 via feed point 406.

In other words, the shade band antenna of the present embodiment is implemented in such a way that the radiator 404 does not intersect the shade members 400 and 402 unlike other embodiments. Of course, even in this case, the shade members 400 and 402 and the radiator 404 may be formed at once through a printing method.

In the above, although the shade members 400 and 402 have a mesh structure, other radiators other than the radiator 404 may be implemented to form the mesh structure with the shade members 400 or 402. In this case, the shade band antenna may implement a multi band by itself.

5 is a diagram illustrating a shade band antenna according to a fourth embodiment of the present invention.

Referring to FIG. 5, the shade band antenna according to the present embodiment is a separate element attached to the glass window, and the substrate 500, the radiator 502, the shade members 504, the feed point 506, and the cable 508 are attached. Include.

The substrate 500 may be FPCB, FR4, or the like, or may be implemented in a film form. That is, the substrate 500 is a concept including both a circuit board and a film.

The radiator 502 is implemented, for example, in the meander type on the substrate 500.

Shade members 504 intersect radiator 502 and preferably cross vertically to form a mesh structure.

An internal conductor of cable 508 may be connected to feed point 506 to provide specific power to radiator 502 through feed point 506.

The cable 508 may extend directly into the vehicle while the shade band antenna is attached to the window of the vehicle to be directly or indirectly connected to a power supply element.

In other words, the shade band antenna of the present embodiment, unlike other embodiments, may be attached to the inner surface of the window as an after-sales service after being present as a separate member instead of being formed directly on the window. Of course, since the shade band antenna should be attached to the glass window, for example, a transparent adhesive may be applied to the lower surface of the substrate 500 so that the substrate 500 may be attached to the glass window.

The arrangement and structure of the radiator and the shade members in the shade band antenna are not limited to FIG. 5, and the arrangement and structure of other embodiments may be applied to the shade band antenna of the present embodiment.

That is, in other embodiments, the radiator and the shade members exist on the same plane, but in the shade band antenna of the present embodiment, the radiator 602 and the shade members 612 exist on different planes. In detail, as shown in FIG. 6A, the radiator 602 is arranged on the first substrate 600 and the shade members 612 are arranged on the second substrate 610. In this state, the first substrate 600 may be arranged on the second substrate 610 as shown in FIG. 6B. Of course, the second substrate 610 may be arranged on the first substrate 600.

Even in this shade band antenna, the radiator 602 and the shade members 612 form a mesh structure, for example, to function as a shade band.
