The present invention relates to a vehicle integrated receiver integrated antenna, and more particularly, to a vehicle integrated receiver integrated antenna that can eliminate the RF (RF) coaxial cable connecting the receiver and the antenna.

Recently, with the rapid expansion of vehicle electronic systems and the development of information and communication, kinds of vehicle multimedia systems have been fortunate.

In conventional FM / AM and analog TV broadcasting, as well as broadcasting of DMB (Digital Multimedia Broadcasting), digital TV, satellite radio, etc., ETCS (Electronic Toll Collection System) or CDM (CDMA, Code Division Multiple) Devices that use RF (Radio Frequency) to transmit / receive information such as access are being installed in vehicles.

A schematic configuration diagram of a conventional vehicle multimedia system is shown in FIG. 1.

Conventional vehicle multimedia system is a control unit for controlling to display the information on the display unit 150 based on the antenna 101, the receiver 120 for receiving a signal from the antenna 101, and the signal from the receiver 120 ( 140).

The antenna 101 includes a radio antenna unit, a DM antenna unit, a GSM antenna unit, a CD antenna unit, etc. corresponding to each of the tuners 120a, 120b, 120c, and 120d.

At this time, each tuner (120a, 120b, 120c, 120d) is connected to the antenna 101 by RF coaxial cables (130a, 130b, 130c, 130d) so that the external signal received by the antenna 101 is RF It may be transmitted to the receiver 120 through the coaxial cable (130a, 130b, 130c, 130d).

However, these coaxial cables 130a, 130b, 130c, and 130d are considerably more expensive than ordinary cables used for signal transmission, and the length of the vehicle is increased or the structure of the vehicle is accompanied by a loss of a signal as the carrier frequency increases. As a matter of fact, when the lengths of the cables 130a, 130b, 130c, and 130d are increased, not only the cost increases but also the signal loss increases.

Accordingly, an object of the present invention is to provide a vehicle integrated receiver integrated antenna that can reduce the manufacturing cost by eliminating the RF coaxial cable, as well as reduce the signal loss by the cable.

According to an object of the present invention, a vehicle receiver integrated integrated antenna includes: an antenna substrate, and an antenna unit including at least one antenna mounted on the antenna substrate; A receiver unit provided at one side of the antenna unit and including a receiver substrate and at least one tuner mounted on the receiver substrate; An antenna output terminal connected to the antenna substrate; It is achieved by a receiver input terminal connected to the receiver substrate and directly connected to the antenna output terminal.

Here, the antenna substrate transmits a signal received from the antenna to the receiver substrate, and an amplifier circuit is patterned on the receiver substrate to amplify the signal.

In this case, the antenna unit further forms an exterior of the antenna substrate and the antenna, and further includes an antenna case having guide protrusions formed on a lower surface thereof, and the receiver unit forms an exterior of the receiver substrate and the tuner, It is preferable to further include a receiver case having a guide groove into which the guide protrusion is fitted.

The receiver substrate is composed of a plurality, it is preferably disposed in the receiver case up and down.

As described above, according to the present invention, since the antenna unit and the receiver unit are integrally formed, the conventional RF coaxial cable can be eliminated, thereby reducing manufacturing costs and reducing the signal loss by the cable as much as possible. A receiver integrated integrated antenna is provided.

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

Figure 2 is a separate cross-sectional view showing a vehicle integrated receiver integrated antenna according to the present invention, the vehicle integrated receiver integrated antenna 1 according to the present invention is a conventional coaxial RF (RF) to the antenna unit 10 and the receiver unit 20 It is characterized by the fact that the terminals 15 and 25 are directly connected to each other by having an antenna output terminal 15 and a receiver input terminal 25 without a cable connection. As a result, the problem of signal loss and increase in manufacturing cost, which occurred when the RF coaxial cable is long, can be solved.

The configuration of the receiver integrated integrated antenna 1 will be described in detail below.

The receiver integrated integrated antenna 1 is connected to the antenna unit 10 having a large external signal, a receiver unit 20 having various tuners 23a, 23b, 23c, and 23d provided therein, and an antenna unit 10.

The antenna unit 10 includes an antenna case 11 forming an external appearance, an antenna substrate 12 provided inside the antenna case 11, and an antenna 13 mounted on the antenna substrate 12.

The antenna case 11 functions to protect the antenna substrate 12 and the antenna 13 from external shocks, and a guide protrusion 11a for fitting into the guide groove 21a to be described later protrudes from the bottom surface. And a ground connection bolt 11b for fitting to the ground connection nut 11c.

The antenna 13 is formed in plural and connected to the antenna substrate 12, and more specifically, the FM / AM / DMB antenna 13a, the CDA antenna 13b, and the GPS antenna (GPS) 13c) and a satellite radio antenna 13d or the like. At this time, the position and type of each of the antennas 13a, 13b, 13c, and 13d may be changed without being limited thereto.

The antenna substrate 12 functions to transmit a signal received from the antenna 13 to the receiver substrate 22, and at this time, the antenna output terminal 15 is connected to the antenna substrate 12.

The antenna output terminal 15 is directly plugged into the receiver input terminal 25 so that a signal received from the antenna unit 10 is transmitted to the receiver unit 20 through the antenna output terminal 15 and the receiver input terminal 25. Can be. As described above, since the antenna unit 10 and the receiver unit 20 are not connected with the RF coaxial cable unlike in the related art, the length of the vehicle body or the structural problem of the vehicle may cause problems between the antenna unit 10 and the receiver unit 20. The problem that the loss of signal or the increase in manufacturing cost that occurred when the RF coaxial cable for connecting the cable is increased can be solved.

The receiver unit 20 is integrally coupled to the receiver unit 20 at the lower side of the antenna unit 10.
