Description

Integrated antenna module for vehicle < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an integrated antenna module for an automobile, and more particularly, to an integrated antenna module for an automobile in which an integrated antenna module integrated with an antenna module and a transmission / reception module can be easily mounted on a roof panel.

An AVN (Audio, Video, Navigation) system mounted on a vehicle, that is, a 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. Not only provides user-friendly operation, but also provides the advantage of efficiently utilizing space such as instrument panel and center fascia of a vehicle.

GPS for Navigation, UMTS (Universal Mobile Telecommunications System) for Telematics, Digital Multimedia Broadcasting (DMB), Digital Audio Broadcasting (DAB), and Satellite Digital Audio Radio Service (SDARS) An external loop antenna is installed in the roof panel of the vehicle.

1, the external loop antenna 11 is mounted and fixed to the roof panel 10 so that it can exchange signals with the transmission / reception unit 14 included in the head unit 13 by the coaxial cable 12 .

As shown in FIG. 2, the external loop antenna 11 is inserted into the loop hole 16 of the roof panel 10 such that the bolt 15 formed integrally or attached to the bottom surface of the loop antenna 11 is inserted And then the nut 17 is fastened to the lower side of the roof panel 10.

Thus, the service signal detected by the external loop antenna is transmitted to the transmission / reception unit included in the head unit through the coaxial cable, and the navigation of the head unit, the telematics, and the broadcast information are acquired.

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

First, although the external loop antenna and the transmitting / receiving unit of the head unit are connected by a coaxial cable for providing each service, it is possible to use two or more such as Long Term Evolution (LTE) or Vehicle-to-X (Vehicle or Infrastructure) In order to apply a system requiring an antenna, more coaxial cables are required, and accordingly, there is a possibility that deterioration due to signal attenuation and signal attenuation due to adoption of a large number of coaxial cables may occur.

Second, in order to assemble the external loop antenna to the roof panel, since the bolt formed on the antenna base of the external loop antenna is inserted into the loop hole and then mounted on the vehicle body using the nut inside the vehicle body, It is necessary to attach a separate pad to the antenna and then tighten the nut. Therefore, the assembling workability is deteriorated and the waterproof performance of the pad deteriorates.

Thirdly, since the entire antenna module needs to be developed according to the design and color specifications of the external loop antenna, it is necessary to develop various loop antenna specifications for each vehicle type, and the number of coaxial cables increases according to radio specifications. There is a disadvantage that the scalability is poor.

Fourth, since the head unit includes the transmitting / receiving unit, there is a disadvantage that not only the signal attenuation due to the coaxial cable connection between the external loop antenna and the transmitting / receiving unit, but also the degree of freedom in designing and internal designing of the head unit is deteriorated.
