Description

Integrated antenna module for vehicle

The present invention relates to an integrated antenna module for automobiles, and more particularly, to an integrated antenna module for automobiles in which an integrated antenna module in which an antenna module and a transmission / reception module are integrated can be easily mounted on a roof panel.

The AVN (Audio, Video, Navigation) system mounted on a vehicle, that is, the head unit is a multimedia system in which an audio unit, a video unit, and a telematics unit including navigation are integrated into one unit. In addition to providing user convenience to operate, it also provides an advantage of efficiently utilizing space such as a vehicle instrument panel and a center fascia.

GPS for navigation included in the head unit, Universal Mobile Telecommunications System (UMTS) for telematics, Digital Multimedia Broadcasting (DMB), Digital Audio Broadcasting (DAB), and Satellite Digital Audio Radio Service (SDARS) An external roof antenna is installed on the roof panel of the vehicle to provide services.

As shown in FIG. 1, the external loop antenna 11 is fixed to the roof panel 10 so as to exchange signals with the transmission / reception unit 14 included in the head unit 13 by the coaxial cable 12. Connected.

In the mounting process of the external roof antenna 11, as shown in FIG. 2, a bolt 15 integrally formed or mounted on the bottom of the base of the roof antenna 11 is inserted into the roof hole 16 of the roof panel 10. After that, the nut 17 is fastened to the bottom of the roof panel 10.

Accordingly, the service signal detected by the external loop antenna is transmitted to the transmission / reception unit included in the head unit via a coaxial cable, so that the navigation of the head unit, telematics and broadcasting information, etc. are acquired.

However, the conventional external loop antenna has the following problems.

Second, in order to assemble the external roof antenna to the roof panel, the bolt formed in the antenna base of the external roof antenna is inserted into the roof hole and then mounted on the vehicle body using a nut inside the vehicle body to ensure watertight performance after assembly. In order for the antenna to be equipped with a separate pad and then tighten the nut, assembly workability is lowered, and there is a risk that the waterproof performance of the pad may be degraded due to the aging of the pad.

Third, since the whole antenna module has to be developed according to the design and color specification of the external loop antenna, it is necessary to develop various loop antenna specifications for each vehicle type, and the number of antennas that can be integrated is increased because the number of coaxial cables increases according to the wireless specification. There is a disadvantage in that it is limited in scalability.

Fourth, because the head unit includes a transmission and reception unit, as well as attenuation of signals due to the coaxial cable connection between the external loop antenna and the transmission and reception unit, there is a disadvantage in that the design and internal design freedom of the head unit is inferior.
